Hi @cashan 1) Yes, using the the CalculiX solver, but the material must be defined using CCX Custom cards, not in the Mecway material definition. Look in the CCX manual how the material is defined at different temperatures. 2) Normally I made a the…

Hi Victor, maybe for future releases, can you add the possibility of grouping componentes in the model tree? Something like subassemblies for easily navigate (by reducing the lenght of the component branch), manipulate (hide/show related sectors of …
-
@prop_desing, that´s means that a CCX version compiled with this new compiler will be fast than the same using other one? And this compiled version (executable) can be distribuited also, or there is some kind of licence that avoid it?
-
Normally for selecting nodes, I hide the element faces, then with box selection the hided nodes (those aligned with one in front) are selected all at once.
-
You can define group of nodes (named selection) before solving, and then in the table result window select the results that you want only in your node group. Regards

@Victor, in the mesh definition, the units once defined are not keeped between parts, so it must be adjusted for everyone. Would be greate to have the mesh definition stored similar to a material, so we could apply it for several parts in the model,…
-
@Victor, have tested a few minuts ago the internal default Netgen mesher against the last standalone version, and activating the multi thread option in the standalone there is a big difference in time to mesh (didn´t measure, but something like 10 t…
-
Don't know what can be wrong on the model, have tested with similar results, anyway the part can be meshed directly in Salome using Netgen algorithm.
-
Hi Victor, can you add the possibility of generate named selection of CAD faces, but with more than one face? Now is possible but limted to groups of one face only. Edited: Actually it´s possible to create named selection of several faces, even fro…
-
@Disla, is very easy to convert a shel mesh into a 3D hexa dominant in Mecway, just extrude the faces towards the thikness direction (+/- element normal), define the thikness and number of layers.
-
Dculp, you can do a mesh refinement based on a node directly, no need to touch the geometry. When you postprocess, select a node with high stress, and then in the contextual menu there is an option to create a mesh refinement in that specific positi…

Is not possible in Mecway, use Paraview fot that.
-
Is a slide control on the icon bar
-
Use the Slice tool on Mecway to slice the view.
-
That was the problem, I start with a modal analysis to check that all the parts of the assembly stay glued, and then change to dynamic response analysis... one hour solving and have finish without velocity results.
-
As far as I know there is no way to save the view in mecway, maybe you can do it in Paraview.
-
A technical report should solve you problem as well :-)
-
I use something similar, by means of the RIGID BODY card to atach the movil nodes to one pilot node, then apply the bc and ask the reactions forces to this single node.
-
If you have the dimentions/material of the oring and groove, I could try to reproduce the simulation and see the force.
-
Dave, the NODE PRINT cards by default gives you all the time increments and steps, there is a modifier to made every n increment. About your problem, guess that you miss to attach the file.
-
Hi @DaveStupple, what I do normally in these cases is define a node set "MOVIL", on the upper surface of the movil part, then create a custom CCX card with *NODE PRINT,NSET=MOVIL, TOTALS=ONLY U,RF CCX will create a separate .dat file with the data…
-
You could try to teach to you CAD team to design with FEA in mind, leaving small features as small radius, chamfers and holes to the end of the model, so is easy then to export a simplified model for FEA without need to further simplification or def…
-
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
