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