NaN results in coronary artery simulation
Posted: Wed Jun 20, 2018 2:51 am
Hi everyone,
I am currently simulating a few coronary geometries and I'm having the following result after mesh partitioning when running the solver in our cluster:
1 4.980E+02 NaN (****) NaN NaN < 2452- 6|****> [ 0 - 0]
1 9.950E+02 NaN (****) NaN NaN < 1664-14|****> [ 0 - 0]
This error occurs in the coronary geometry with the aberrant origin of the right coronary artery (see attached file, left) while the other one works just fine. Boundary conditions have all been taken from the website tutorial. I checked the quality of the meshes with Paraview and everything seems OK. I used radius-dependency in the coronaries and a fixed edge length in the root of the aorta. Different parameters for this meshing scheme derive in the same problem in the solver.
Any hints for the behaviour in this particular geometry?
Many thanks,
Rodrigo
