I am splitting this issue off from the other thread on problems with the SUPG implementation in ASPECT. I have encountered failures to converge when using the SUPG implementation in ASPECT. These convergence failures happen seemingly randomly and usually after a model has been running for a long time, making them difficult to diagnose. I have been working to provide a simple testcase that fails quickly and believe that I have something that works… err crashes quickly . Because I do not see a way to easily attach files on the forum, I opened an issue report on github related to SUPG issues. It is here:
I would welcome some insight from anyone who is more familiar than I am with the SUPG implementation in ASPECT.
All the best
