It worked.
I changed the "Slope of pressure-overclosure curve K" in the contact parameters from 2000 GPa/m to 20000 GPa/m.
The only issue with remeshing is that Netgen/ngmesh says it cant do it, because there are too many trig neighbours or some…
It's a bit difficult to add contacts to the faces since the cylinders are so close to each other, and this is a single model STL mesh, so I can't "hide" individual cylinders.
But I got around the issue. It was quite complicated. Even then, the resu…
This is an image of what I'm getting. It's not what I want. The colourful protrusions are the elements of the most inner cylinder. The pressure applied is only to that cylinder, but all the cylinders have a fixed support.
The outer cylinders should…
The PipeClip.liml example using the Calculix solver worked well. The ddfem version didn't run/install for me, but the bConverged version was easy to setup for solver association.
I'll upload an image of a case using my own Tri6 geometry, since I'm …
They're meant to be initially separated. I'll try the "Nonlinear Static 3D" analysis. But I would like more details on how to proceed. I'm not sure what the convergence criteria should be set to.
Also, since Nonlinear Static 3D requires elements of…
