Currently, I tried two algorithms and I have the same result.<br class=""><br class="">1) Algorithm 1<span class=""> </span><br class="">err = SNESSolve(_snes, bc_vec_test, solution);<br class="">CHKERRABORT(FOX::Parallel::COMM_WORLD,err);<br class="">PetscViewer vtk;<span class=""> </span><br class="">PetscViewerVTKOpen(FOX::Parallel::COMM_WORLD,"solution.vtk",FILE_MODE_WRITE,&vtk);<span class=""> </span><br class="">VecView(solution,vtk);<br class="">PetscViewerDestroy(&vtk);<br class=""><br class=""><br class="">2) Algorithm 2<br class="">err = SNESSolve(_snes, bc_vec_test, solution);<br class="">CHKERRABORT(FOX::Parallel::COMM_WORLD,err);<br class="">PetscViewer vtk;<span class=""> </span><br class="">PetscViewerCreate(FOX::Parallel::COMM_WORLD, &vtk);<span class=""> </span><br class="">PetscViewerSetType(vtk, PETSCVIEWERVTK);<span class=""> </span><br class="">PetscViewerFileSetName(vtk, "sol.vtk");<span class=""> </span><br class="">VecView(solution, vtk);<span class=""> </span><br class="">PetscViewerDestroy(&vtk);<br class=""><br class="">The result seems correct except for the rotation order of the nodes (see the red lines on gmsh and vtk file respectively). Then, I visualized my vtk file with paraview, and I remarked that my geometry is not correct and not conserved when comparing it with my gmsh file. So, I didn’t understand why the rotation order of nodes is not conserved when saving my result to a vtk file?<br class=""><br class="">Other information used:<br class="">- gmsh format 2.2<span class=""> </span><br class="">- Vtk version: 7.1.1<br class="">- Petsc version: 3.13/opt<span class=""> </span><br class=""><br class="">Below my two files gmsh and vtk:<br class=""><br class="">Gmsh file:<br class="">$MeshFormat<br class="">2.2 0 8<br class="">$EndMeshFormat<br class="">$Nodes<br class="">12<br class="">1 0.0 10.0 10.0<br class="">2 0.0 0.0 10.0<br class="">3 0.0 0.0 0.0<br class="">4 0.0 10.0 0.0<br class="">5 10.0 10.0 10.0<br class="">6 10.0 0.0 10.0<br class="">7 10.0 0.0 0.0<br class="">8 10.0 10.0 0.0<br class="">9 20.0 10.0 10.0<br class="">10 20.0 0.0 10.0<br class="">11 20.0 0.0 0.0<br class="">12 20.0 10.0 0.0<br class="">$EndNodes<br class="">$Elements<br class="">2<br class="">1 5 2 68 60 1 2 3 4 5 6 7 8<br class="">2 5 2 68 60 5 6 7 8 9 10 11 12<br class="">$EndElements<br class=""><br class="">Vtk file :<br class=""># vtk DataFile Version 2.0<br class="">Simplicial Mesh Example<br class="">ASCII<br class="">DATASET UNSTRUCTURED_GRID<br class="">POINTS 12 double<br class="">0.000000e+00 1.000000e+01 1.000000e+01<br class="">0.000000e+00 0.000000e+00 1.000000e+01<br class="">0.000000e+00 0.000000e+00 0.000000e+00<br class="">0.000000e+00 1.000000e+01 0.000000e+00<br class="">1.000000e+01 1.000000e+01 1.000000e+01<br class="">1.000000e+01 0.000000e+00 1.000000e+01<br class="">1.000000e+01 0.000000e+00 0.000000e+00<br class="">1.000000e+01 1.000000e+01 0.000000e+00<br class="">2.000000e+01 1.000000e+01 1.000000e+01<br class="">2.000000e+01 0.000000e+00 1.000000e+01<br class="">2.000000e+01 0.000000e+00 0.000000e+00<br class="">2.000000e+01 1.000000e+01 0.000000e+00<br class="">CELLS 2 18<br class="">8 0 3 2 1 4 5 6 7<br class="">8 4 7 6 5 8 9 10 11<br class="">CELL_TYPES 2<br class="">12<br class="">12<br class="">POINT_DATA 12<br class="">VECTORS dU_x double<br class="">2.754808e-10 -8.653846e-11 -8.653846e-11<br class="">2.754808e-10 8.653846e-11 -8.653846e-11<br class="">2.754808e-10 8.653846e-11 8.653846e-11<br class="">2.754808e-10 -8.653846e-11 8.653846e-11<br class="">4.678571e-01 -9.107143e-02 -9.107143e-02<br class="">4.678571e-01 9.107143e-02 -9.107143e-02<br class="">4.678571e-01 9.107143e-02 9.107143e-02<br class="">4.678571e-01 -9.107143e-02 9.107143e-02<br class="">1.000000e+00 -7.500000e-02 -7.500000e-02<br class="">1.000000e+00 7.500000e-02 -7.500000e-02<br class="">1.000000e+00 7.500000e-02 7.500000e-02<br class="">1.000000e+00 -7.500000e-02 7.500000e-02<br class=""><br class="">Thank you in advance and have a good day !<br class=""><br class="">Sami,<br class=""><br class="">--<br class="">Dr. Sami BEN ELHAJ SALAH<br class="">Ingénieur de Recherche (CNRS)<br class="">Institut Pprime - ISAE - ENSMA<br class="">Mobile: 06.62.51.26.74<br class="">Email:<span class=""> </span><a href="mailto:sami.ben-elhaj-salah@ensma.fr" target="_blank" class="">sami.ben-elhaj-salah@ensma.fr</a><br class=""><a href="http://www.samibenelhajsalah.com/" target="_blank" class="">www.samibenelhajsalah.com</a><span class=""> </span><<a href="https://samiben91.github.io/samibenelhajsalah/index.html" target="_blank" class="">https://samiben91.github.io/samibenelhajsalah/index.html</a>></blockquote></blockquote></blockquote></div></blockquote></div><br class=""></div></div></div></blockquote></div><br clear="all" class=""><div class=""><br class=""></div>--<span class=""> </span><br class=""><div dir="ltr" class=""><div dir="ltr" class=""><div class=""><div dir="ltr" class=""><div class=""><div dir="ltr" class=""><div class="">What most experimenters take for granted before they begin their experiments is infinitely more interesting than any results to which their experiments lead.<br class="">-- Norbert Wiener</div><div class=""><br class=""></div><div class=""><a href="http://www.cse.buffalo.edu/~knepley/" target="_blank" class="">https://www.cse.buffalo.edu/~knepley/</a></div></div></div></div></div></div></div></div></div></blockquote></div><br class=""></div></div></blockquote></div><br clear="all" class=""><div class=""><br class=""></div>-- <br class=""><div dir="ltr" class="gmail_signature"><div dir="ltr" class=""><div class=""><div dir="ltr" class=""><div class=""><div dir="ltr" class=""><div class="">What most experimenters take for granted before they begin their experiments is infinitely more interesting than any results to which their experiments lead.<br class="">-- Norbert Wiener</div><div class=""><br class=""></div><div class=""><a href="http://www.cse.buffalo.edu/~knepley/" target="_blank" class="">https://www.cse.buffalo.edu/~knepley/</a><br class=""></div></div></div></div></div></div></div>
