Dear all,
I am a new user.
When I tried the VCSMapping with test case
(nektar/solvers/IncNavierStokesSolver/Tests/CylFlow_Mov_mapping.xml)
it failed to run in parallel with errors:
"
mpirun -np 8 IncNavierStokesSolver CylFlow_Mov_mapping.xml
Fatal : Level 0 assertion violation
A parallel solver must be used when run in parallel.
"
I had to run it in serial to get the final result. However the mesh
grid and the position of cylinder remain the same as initial
field, even if I have tried different "NumSteps".
I just followed the user guide and used
"FieldConvert CylFlow_Mov_mapping.xml CylFlow_Mov_mapping.fld cyl.vtu"
to get the converted result.
I guess maybe because 'CylFlow_Mov_mapping.xml' only contains initial
mesh data and CylFlow_Mov_mapping.fld only contains
field data, i.e., deformed mesh information is missed by this command.
so I think this problem is about post-processing.
Could you please help to find out what I've missed and fix this problem?
I would appreciate your Help.
Kind regards,
Hanbo
