The integration with OpenRadioss looks amazing, same for Alibre Desing. I think that Alibre + Mecway is the ideal setup for freelancers engineers/analyst. I can't wait to have a moment to try out all these new tools!
-
Did you try to export the CAD from Solidwork (remove small components before) as an STL and import in Mecway? With solid meshes sometimes I export the results to Paraview and then import also the CAD model to compare there. With this kind of struct…

If two or more named selection could be visible at the same time, then would be usefull having the oportunity to define different color for them also.
-
I suffer that problem designing and testing (FEA and physical tests) an engine mount aluminium bracket twenty years ago (or more). For low loads the initial bolt preload was enough to keep the part in place with the bolts centered in the holes (slot…
-
Yes, for models by made several components takes a lot of time to create the TIE bc. Automatic contact detection would be great.
-
I'm sharpening my arguments to propose OpenFOAM support as well :-)
-
Hi @Thomas, it looks like an old feature of NX Nastran where we could compute some unit load cases, and after combining and doing some calculation.
-
@FERNANDO, of course, working outisde Mecway is 10x more complex and time consuming. Still I don´t understand why also in Paraview as in Mecway cannot pick a node and get the field variable as with CCX results. In this example the 2d plot is from a …
-
@FERNANDO , I was able to postrocess in Paraview and request/post energies!
-
@Bcavender for such kind of part the best is to mesh in Salome using structured quads and then extrude to get the requied hexas and length. You could try in Mecway using gmsh also, but will not let you control the quantity of elements in each side a…

@Fatmac we thought CCX had a complicated syntax...OpenRadioss is perverse, that fixed format is breaking my head!!!
-
@FERNANDO, I did a few test yesterday, and even some more variables can be requested as results adding some cards in the custom engine file, for some reason I cannot postprocess as the native or CCX ones, units are fixed and when I choose one node t…
-
Uf, that would be incredible, having Openfoam running natively from Mecway interface. Do you know @FERNANDO that you can prepare Openfoam models in Mecway? But for solving you need the command line, and postprocess in Paraview.
-
Yes, I took the /BCS from the tubes examples and is working, even with symetries. Thanks a lot for bringing OpenRadius to us! Now that there are three solvers available, would be very interesting show the name of the solver in the post view, maybe w…
-
@Victor, in the impact model, in which part of the Openradioss instructions you tell that the lower part is "fixed"? I'm tring to make a new similar model but my lower part flies away when it gets in contact with the impactor as it would be free :-(
-
❤❤❤❤❤ can't wait to start crashing things! Thanks!

If you have access to SW, do the modeling there, including the sewing and partitions. Then export as step to Salome or Mecway. If the surfaces are sewed in Mecway you can get good enough meshes.
-
3rd party mesh tools free or inexpensive...probably Mecway is the unique. There is Salome, Gmsh, Netgen, TetGen that are free (even CGX). Gmsh and Netgen are integrated in Mecway and Salome. On the comercial (from expensive to very expensive) side y…
-
In ANSYS workbench, you model your geometry as a surface? and then in Mechanical you make a shell mesh? If that the case you could model your parts in any standard CAD program as Solidworks, Solidedge, FreeCAD as conected surfaces and then import in…
-
I have recovered an old model of a simple compressor that works similar, I will create another version as soon as possible with even more simplified components, including the con rod bolts, piston rings and cylinder liners, and adding a load on a to…
-
Would be possible to make it dynamic and also include inertial forces due to rotation (at least at constant speed)? The ideal model would include also connecting rods and piston, and an external force in the piston head. There is a recent video on …
-
Another test that you may do is extend the surfaces in SW (away from the target), and then trim the excedent with the other, and finish with a sew command in SW before importing in Mecway.
-
Are you sure that the surfaces are perfectly touching in CAD? Were all generated by the same kind of operation? Some times the extend surface operation gives some degenerated edge that doesn´t allow a connected mesh. If I remember well there is a to…
-
I did something very basic python script to make a kind of bill of material/parts and include material properties, element type, node and element numbers last years, but using the Mecway API functions. It gives a raw text file that can be easily cop…
-
There is also an issue related to the number of the nodes, if I rememeber well the size in memory of the problem depends not only in the quantity but also in max number of nodes, so if you have deleted or imported parts with no correlative nodes num…
-
Interesting problem, normally I do that on the CAD by spliting surfacces, but in an orphan mesh... My first try was create a hole with the Menu/Mesh Tool/Hole (using the washer diameter), and then select all the faces around the hole with the Edge …
-
@Victor , Alibre assembly support will be a great advance. Will use native or step files created by the application?
-
Normally I create first named selections with names following a simple naming convention. This selections can be based on geometry or sometimes directly on meshes. Then the bc are applied to these named selections, and the name of the selection help…
-
If the parts are in contact and perfectly modeled in CAD, you can export the assembly to Salome and mesh there with coincident nodes and avoid the bondad contact issue. Then export the mesh as unv with groups of elements for every component and impo…
