I will try to export as 3D DXF as @ehoule says, maybe the Salome meshing could be avoided.
-
Just to share my procedure, have worked months ago with roll cages made of tubes. The best way that I found was to model the assembly as wires in FreeCAD, using standard 2D sketchs for the tubes lying in a plane (most of them), and 3d curves (Dwires…
-
The only solution for this cases that I have found is just finish the work and export the mesh as .unv.
-
Mishal, the customer ask for 3D elements and FEA checking.
-
If your model is made by standard beam profiles, you should mesh in Salome in order to use hexa elements and keep the node/element count low, otherwise using automatic tet mesh and at least two element in thikness would lead to unsannely big mesh. C…

Thanks Victor, will try at least to solve in 2.16. It's incredible, I have working in this issue for at week at least :-(
-
Hi Victor, related to this issue, could it be the solver log be saved within the liml file? Sometimes one want to know why it has failed or time to solve after the window has been closed.
-
I prefer to be plastic strain only to keep in line with CalculiX documentation
-
Looks like the Pastix build has matured, is available compiled for Windows or one must do the procedure?
-
Would be great to have this instruction (install Pardiso and configure multiprocessor) as a stikie post in the forum (very like the welcome post), lot of people ask for them.
-
Hi, maybe you could do the first point using the CCX solver and Cyclic Symmetry boundary condition (you model one slice and you have the result for the whole pizza), about stacking... that could be done on Paraview translating the CCX results to rme…

Have tried SharkCAD and ViaCAD years ago, they are not better than the Alibre basic package. These days have a project where I need to model tubular frames, did the first one with FreeCAD, and start to try Alibre, but they lack some basic feature as…

I add another, in the Stress Linearization feature, can be the SCL visible when is definied? Now is only visible the nodes, and the line appear when the stress linearization window is closed. Also, when the saved SCL is clicked on the model tree, wi…
-
That's the exactly procedure, normally you should mold standard samples (cilinders about 32 diam and 18 in heigh if I remember well) with your specific rubber, then you measure on a dinamometer the load deflection curve in compresion. After that you…

I just trying (suffering) FreeCAD also, but you can take a look at Alibre, they have a basic CAD package for about usd 120 that... has less features than FreeCAD but at least a civilizated interface. You can try also Onshape or Fusion360.
-
There is an option to launch Mecway from command line to solve a problem without opening the GUI. Anyway being able to it directly from the interface would be great, now for big problems take a lot of memory to show it plus to solve it. Look in the …
-
As everybody says, I'm waiting also an inspired hero that compile this new version.
-
Since I installed Pardiso never back to Spooles!
-
Have someone worked with CFD using CCX?
-
Well, there are a lot of steps to get the mesh 1) Be carefull while modeling, keep radius constant and realistics, better to model as surface and then add the thikness to check that also the mesh could be extruded 2) In CAD add extra face divisions…
-
Hi, just to revive this thread, attached is an example of the secuency of modeling (with OnShape) and meshing (using Salome) with quads and then extruded to get hexas of a bracket made in steel sheet, very similar to the one of @JohnM . It takes a l…

This is a very usefull plastic material database, it has properties and stress/strain curves for lot of comercial polymers, and even at different temperatures. https://www.campusplastics.com/

@tk1537 , if I understood well, following the option 4) what you would get is CCX with out of core capacity. The CCX executable available from CalculiX site works inside of core (put all the stiffnes matrix in RAM only), so if your problem is too b…
-
Licences :-(
-
Is there a reason why is not readily available an out of core MKL version of CCX?
-
Is increddible, but I have exactly the opposite experience on your points, I do 90% of my meshes using Netgen, even feel more comfortable with the standalone version of it than Gmsh. And again, I found very usefull Salome, mostly for creating struct…
-
Can you share the geomety? Normally what I do is split the faces in the CAD program available, then export the cad to Salome were I mesh with quads, the extude to create the hexas. Another way would be creating the elements in Mecway directly, but c…
-
For that kind of part I would suggest to use hexa elements, and have at least 2 second order element in thikness.
-
@rwhirley , you can postprocess the results and do the simmetry using Paraview.
-
Congrat, I'm testing mostly the improvements in display performance for big models, and looks very well. One thing, while I was solving a problem, have tried to test the center of mass tool, it open the window but as it doesn't have defined densit…
