Hello,
We have recently updated the WE-UQ to V3.1.1, addressing some bugs. Can you now check with:
1. Download the latest version from
https://simcenter.designsafe-ci.org/research-tools/we-uq/.
2. Open WE-UQ, and in the File -> Preference, reset the paths by clicking "Reset" at the bottom.
3. Clean your working directory path from previous simulations.
4. Then run the background mesh and check if everything works.
If this doesn't seem to fix the issue, we can schedule a zoom meeting and take a closer look
Best
Abiy
