Bug with Octree #26

Open BillyTheKidPhysicist opened 4 weeks ago

BillyTheKidPhysicist commented 4 weeks ago

When I run the attached model with "Particles-DSMC-UseOctree = T" I almost always get the error " Negative determinant of Jacobian in calc_df_inv" eventually. I've included the docker file as well. This is with BGK-Flow and version 3.3.0. The error occurs even with DSMC. I just got the model to work by turning off nearest neighbor though.
