Dear, I have two doubts: Dear, I have two doubts: 1st question - According to the example below, I have two volumes and I would like to consider two different types of mtarial in each volume. The model considers the individual volumes in gmsh using BooleanFragments. However, how do I consider ea…

Dear @dokken , Thank you very much for your answer! It would be like the code below: My question was on line 32, do I call dx1? Is correct? I did a test by inverting the materials and the displacement result was the same as if it were all the material with the greater Em. I see that there should …

[image] Rafael_Ferro: My question was on line 32, do I call dx1? Is correct? Its not very clear what you are asking. You are not using dx1 and dx2 in the correct way. Note that your example is far from minimal (as you could have stopped the whole example after generating vm, and visualize i…

Dear @Dokken , Thanks a lot for your help, it works now. What about considering this model as a mechanism? Create a form of contact between the volumes, effectively “separating” the meshes, or even a way to reduce the degrees of freedom between the nodes that are shared between the two volumes, rel…

Dear @Dokken , As I said before the code is working. However, I went to test in parallel mode and there was the following error: Traceback (most recent call last): File "OTE_Two_cantilever_static_3D_two_material.py", line 181, in <module> rho_n = interpolate(Constant(float(Vol)), W) #Control …

What code is throwing this error? I cant help you by just seeing an error message and not a minimal code that reproduces the error.

Dear @Dokken , I’m still working on the code here, I’ll try to simplify it and then I’ll post it here. Taking advantage of the post, another question arose, is there a possibility of isolating or removing one of the two volumes in the final result? Any function via XDMFFile where I show the final r…

[image] Rafael_Ferro: antage of the post, another question arose, is there a possibility of isolating or removing one of the two volumes in the final res You should be able to do that by using MeshView and projecting the solution from the parent mesh onto the submesh.

Well, I don’t use Docker anymore. Is there another way to install this latest version with Meshview using conda or another way to resolve this volume situation using another Fenics feature or even a Paraview feature?
