I have imported the dxf over an empty new file in Mecway, and the error appears. If I try open in place of import, I can import it and see in the tree that there are x elements (the number of lines of the dxf), but nothing in the model display area …
-
Have checked with other files (solid steps), and I was able to import the 3d model, but is not visible. After meshing the same error appear, so probably is a problem with this particular Windows installation. One interesting thing that I found was …

Have imported the lines in Salome (as igs), then mesh as 1D element and export as UNV and import in Mecway with the same error
-
Have uninstall/reinstall the new version and still cannot open dxf, the error is the same
-
Thanks for checking, I will try to re-install, as I have the same version as you. A very weird thing because last week the dxf importing was working ok on this machine. Regards

You could solve the problem as no lineal with lineal material properties. "If you want to control the sequence in which loads are applied or ramp them up gradually, check the Quasi-static box and specify the Time period and Time step size under Ana…
-
If you upload the steps incuded in the model I could give a look later. Take a look on the forum, there is another thread with something very similar.

Jola, do first a 2d quad dominant mesh on all the geometries, and then just extrude the faces that you need to create the hexas/wedges. Then you can delete all the rest 2d elements
-
Hi Jolan, welcome on board! One of the mantra of my first FEA mentor (a venerable French guy also) was... "Sergio, remove all the unnecessary areas of the model" and he was very right! Removing the features and volumes that will not help you on the …

You can separate the faces on your CAD leaving only the cross section and just export this faces, then mesh with cuads and revolve it and create the holes using the specific tool. For meshing with coincident nodes you can mesh it on Salome, or Gmsh…
-
One thing that I do in some cases is reduce the quatity of datasets that CCX saves, so by example 1 every 2, or 1 evry 5 in some cases or less. This reduce the global size of the result file. Use the FREQUENCY parameter on the NODE FILE card: "FRE…
-
Nice model! Can you post an animation of the results? Regards
-
I would reorient the geometry in the CAD program to the real position before meshing in order to avoid such problem.
-
If you will use hyperelastic materials then will be a no lineal analysis, with several (lots) increments. Pay attention to create the more efficient mesh in order to have a model that can be solved in a short time. With that you can make several tri…
-
To replace the TIE you can try to mesh with coincident nodes in Salome, but for that you need the geometry in stp format.
-
Hi Swaraj, welcome then! I'm working on a similar project. Have sense to include in the model such a soft tissue? I meant, jaw bone will be several orders of magnitud stiffer than the PDL. Check this article about Jacobian error, maybe you could tr…
-
You can insert those cards directly using the Mecway inteface (custom CCX data) and see the results on Mecway directly. I don´t have experience with results with the coordinated system changed, I use the TRANSFORM to apply cilindrical bondary condit…
-
Hi Tim, in CCX with the *TRANSFORM card you can create a new coordinate system (rectangular or cilindrical, related to an specific node set), don't know if t will serve to your matters. Also the *NODAL FILE card (used to store the nodal results in t…
-
In CCX you can use the card NODE PRINT and ask for the RF (reaction forces) on the node (must be a node set). CCX will write reaction forces and reaction moments in a separated text file (extension .dat). Read the CCX documentation about that card.
-
Probably you are applying two different restrains to the same node. Sometimes happens on the simmetry planes. Upload the model and maybe we could understand it quicker and give a better answer.
-
Can you share the .liml files with the associated steps files?
-
The part must be well positioned in the CAD before exporting to Mecway. You could move it in Mecway, but the CAD will be quicker, easy and more accurate than moving/reorienting the mesh.
-
You can hide/unhide components of the assembly in CGX directly, you must open the .frd and .inp files from the command line. Check the CGX documentation or look in the CCX Yahoo list, I remember that this question was answered there.
-
The part of the calculus that do the loading.
-
If I had undertood well, you need to model the plate first without interescting the cuboid, and then by means of a static step move it (including contacts) in X direction to the final position to see the stress on the assembly. After the plate is on…

The iterative scaling option doesn't work. Have tested with 2.11 and 2.13.

Hi, I have tested other comercials solvers on the same machine (Intel i7-3632QM @2.2Ghz / 8GB RAM), with the same model/bc, and found that while was unnable to solve with CalculiX, even with half of the resources (cores and memory) the other ones so…

Victor, for CCX and no lineal models, is possible to implement on next version the FRECUENCY option for saving data every x increment?
