Regional Refinement issue
Posted: Wed Apr 17, 2019 2:35 am
Dear SimVascular community,
I'd like to launch a simulation with both boundary layer meshing and regional refinement. My model is an aorta with a coarctation, and I'd like to refine the mesh in the coarctation region.
I was able to generate the mesh using TetGen successfully. When I attempted to launch the simulation, it finished immediately. The folder "n-procs_case" was correctly creating, but no restart file and svLS_NS.log were created. I performed the boundary layer meshing, setting up the following parameters:
Without the local refinement, it was possible to launch the simulations with different max edge global sizes and setting only boundary meshing refinement. As max edge global sizes, I entered: 0.15, 0.12 (estimated max edge global size), 0.105 and 0.08 and the simulations ran successfully with all of these parameters.
In the attachments, you can see some images of the mesh, obtained setting both boundary layer meshing (as previously indicated and by means the estimated max edge global size) and regional refinement (setting up 0.06 as local size).
Your help would be appreciated.
Thanks in advance,
Maria Nicole.
