The Moldex3D Mesh plug-in accesses the newly-enhanced and versatile functions of Rhino 5. Moldex3D Mesh supports numerous mesh types, including 2D triangular and quadrilateral meshes and 3D tetrahedral, prismatic, hexagonal, voxel brick , and pyramid meshes. Among the automatic and semi-automatic mesh generators that are available in Moldex3D Mesh, the Boundary Layer Mesh BLM generator is the most powerful one for complex geometries. The BLM generator allows users to firstly generate inward one or two layers of prismatic meshes out of the triangular surface mesh of the object, followed by filling up the internal space with quality-controlled tetrahedral mesh. With this unique BLM, FEA solvers can capture the variable distribution, such as temperature, more accurately with much less number of elements than the isotropic tetrahedral mesh.
In a rectangular frame, the principal axes 1, 2 and 3 correspond to the X, Y and Z axes, respectively. The Euler Create action creates a new coordinate frame through three rotations from an existing coordinate frame. The view vector is the most important aspect of building a composite trimmed surface. The conversion was not perfect as you can imagine Sri escort this was a total nightmare! For more information on using MSC. No notes for slide. If the surface mesh does not contain gaps only the outline and sharp edges should be visible in the preview window.

Software: Patran Forum Patran solid mesh : thread Patran does not recognize them as solids so I can not do a solid mesh. How do you get around this problem? Regards Onda. Hi, I would like to add to that thread. I have a very complexe 3D geometry with a lot of surfaces. Actually, only few of those surfaces are really of some interest to me.
I want to do a 3D FEA. I would like to know if there is any easy way to refine the 3D solid mesh on those specific surfaces without having to mesh each surface individually which would take forever and then mesh with TET10 elements. Also, the surfaces on the solid are usually not biparametric so an isomesh is impossible and then controlling the mesh is harder.
I have heard that Patran was pretty good in terms of 3D meshing, but so far, I can't see why one would think that. Unless I am missing something. Any advices? Thank you very much. Hi, could you post an image of your geometry to better understand? Here is a pictures of the geometry, hope this helps. Hi Francois, If you have your solid model in Catia isn't it? Then Patran should recognize as solid and mesh it without problems. If Patran do not recognize as solid and You don't have any way to do it then: Mesh the model with the sheetbody option using Tria3.
Using sheetbody you could mesh many surface as only one. Seed the mesh where edges are non coincident in way to obtain a closed shell mesh. Then use the previous posted procedure to obtain a solid Tet10 mesh from the shell Tria3 mesh.
I'm afraid that with Patran You couldn't mesh your model with Isomesh. Onda Thanks for the answer. The problem with that model is not that Patran do not recognize the solid. It does and I can mesh it using TET elements without too much problems.
What I am trying to do, is to refine that TET10 mesh on specific surfaces or portion of the geometry since high stresses are found only at some few specific locations. For now, I haven't found any possibility to refine localle a 3D mesh. Is it at all possible? I will try the sheet body option see what I can do with it.
Hi Francois, Sorry, I misunderstood your point. You could try, if you have a solid, to make a mesh seed on borders of surface that you want to refine. In this way you could force the dimensions of elements close to the borders. You should also reduce the Minimum edge length to 0.
If this is not enough you should go for the long way. Mesh using tri elements and then convert to solids. Using shell elements you are able to refine any location you want but for sure it take a lot more time! Red Flag This Post Please let us know here why this post is inappropriate.

Thus, it is recommended that you try to use another format, if possible. Imported and exported models include many common entities in the Nastran bulk data. Abaqus provides a translator plug-in for NX that will generate a geometry file using the Elysium Neutral File.
OBJ is an open file format that describes the geometry in terms of the position of the vertices, the edges between them, and the faces that comprise each polygon in the geometry. Data in OBJ format are saved as a text file.
Parasolid is a library of solid modeling functions developed by UGS. You can import Parasolid-format parts. The STEP AP standard is designed to provide a computer-interpretable representation of a mechanical product throughout its life cycle, independent of any particular system. In addition, you can import and export sketches in STEP format. It is an open, platform-independent, vector-based, three-dimensional modeling language that encodes computer-generated graphics to allow them to be shared easily across a network.
VRML files use meters for all lengths and distances. VRML-format files can be many times smaller than typical model database files.

I love to answer questions from the readers of my blog… especially when they are good. Why not writing an article to explain the whole stuff to CAE beginers?
I always remember this clients who sent me the CAD file of a small pleasance boat and then told me:. Time to change the gears and go in the second mode: Finding what happened and why. There was something that the client omitted to mention… the solution often lies in what is NOT told…. The client had his own software to analyze small boats and he was generating himself the shapes and then saving the file into a standard STEP format.
But first to understand that, you have to understand 1 what is a CAD file and 2 how data of a geometric model are saved. Because most of the communication systems and channels that we build are based on text and words , not on visual things. I would take each basic components of my geometry one by one and I would try to describe it using pure geometrical coordinates. A finite element model is much more easy to decompose like that than a pure cad model because it uses only very simple shapes.
Such files are used everywhere and especially in FEA where you need a simple way to make an interface and communicate between the graphical interface, the solver and the results. Because of that companies have all created their own formats which all have their particularities. Because it had been generated by a very non standard process and was including some NURBS curves that are not supported by CAE and cad software in general. The main reasons are that:. The result is often the same than trying to translate english into chinese with google translate and then translating back chinese into french and then into english… your 2 english sentences will probably be totally different… I let you try.
This ICAM Integrated Computer Aided Manufacturing Project was created to develop procedures and processes that would help to integrate all the operations in the Aerospace manufacturing industry.
In short, they wanted to create CAD software that would generate automatically all the procedure required to control machine tools that would manufacture the mechanical parts in the aerospace industry and they succeed by the way ;-. Those images were taken from the wikipedia article here. The geometric data are present in 2 different sections of the file but in different formats. The STEP format started to be developed in as a successor of IGES format…and the main purpose was to represent all the information of a product inside one unique software-independent product model file.
In the following years, the capabilities of STEP were widely extended, primarily for the design of products in the aerospace, automotive, electrical, electronic, and other industries. You can learn more about it from this wikipedia article if you are interested. This geometric modelling kernel can be licensed by other companies to use its functionalities inside their 3D CAD or CAE software products.
The most common extension you will find for a parasoled file is the extension. There is also another binary format. If You want to know more about the parasolid CAD format, you can read this article on wikipedia.
You understood through this article though that there is a difference between different CAD formats. Those formats are great because they are supported by all CAE software as a way to exchange model information they were created for that. Proprietary CAD formats are useful for vendors because it helps them to store data more specific to their software and it is also a way to protect their technology of course….
If you like this article, there are 3 things you can do for me:. I know, but BREP has a better way of handling geometric primitives than most of the other formats so I wondered why it was not addressed in the first article of a series.
Thanks Cyprien for your article and you both for your replies. Hello and thanks for this article. I just have one question since my English is not that great. Thank you again,. Bonjour Charlotte, Vous avez bien compris. Thank you for the detail explanation. I learned that STEP file is better in IGES file, because it is richer in material information, tolerances and topology, but in general, if I understand correctly, IGES file carries geometry information, but not the connection of the geometry.
Any software that reads IGES file has to deduce the connection on its own. Is this understanding correct? Thanks for giving me insight into this which all of us usually ignor.
I never knew the intricacies of the savable formats. Firstly thanks for the clear insights in your articles. Can you give some suggestions on results validation point of view? I am finding difficult in validating my results though i go by process of defining boundary conditions, type of analysis and material selection. Can you provide any source of your articles to understand the back end solution of analysis one performs.
CAD software at the time was unable to save a model in standard types too, like. The conversion was not perfect as you can imagine and this was a total nightmare!
I can imagine… converting formats is really a headaches! Two Extremes…. For example this format is basic on NX and Catia. I am beginner of using FEA. Thank you for this great article. This libraries are very complete and useful. But was very hard do decode the documentation in french. Original: The result is often the same than trying to translate english into chinese with google translate and then translating back chinese into french and then into english… Translated: The result is usually the same as using Google Translate to translate English into Chinese, then Chinese to French, then translate it into English….

Thanks in advance, With regards. By the way. I did the translate chalenge and the result was: Original: The result is often the same than trying to translate english into chinese with google translate and then translating back chinese into french and then into english… Translated: The result is usually the same as using Google Translate to translate English into Chinese, then Chinese to French, then translate it into English… Looks like Google are very eficient in theese translations, lol.
