Here is a link to my project:
This is my first attempt to use SimScale and my goal is simply to deform a part and measure the total strain.
I have followed the “Aluminum pipe bending” tutorial, and I tried to set my simulation up using the same approach. I 've spent about a day and a half trying to work through this by tweaking boundary conditions, contact settings, material settings, numerical settings (tried most of the different direct and indirect solvers) and geometry, but I cannot get this simulation to solve.
This is the error I’m getting:
- The solution matrix is singular. This may be caused by an unconstrained rigid body motion, a physical contact definition with open gap in a nonlinear static analysis or incoherent material parameters
I believe all my bodies are properly constrained, and there is no gap between parts (line to line contact). My material parameters were taken from a true S-S curve of nitinol wire, and I believe I’ve input things correctly. I’m really not sure where I’ve gone wrong here, so hoping someone who is an expert in SimScale might be able to help me figure this out.
Here is an image illustrating what I want to do. I simply want to deform the part like shown and measure the total strain.
