Hello,

I need to visualize my 3D mesh that is decomposed to n subdomains in a single image, purpose is to show construction of subdomains, I used ‘medit(“Th”+mpirank, MThi);’ but it shows each subdomain separately. how can I show them all in once like in different colors attached together?

Thanks.

It is possible (see e.g. [FreeFEM-tutorial-public/meditMPI.idp at master · fotios-kasolis/FreeFEM-tutorial-public · GitHub](https://github.com/fotios-kasolis/FreeFEM-tutorial-public/blob/master/code/meditMPI.idp)), but I would advise you to simply use savevtk (example: [FreeFem-sources/laplace-adapt-dist-3d-PETSc.edp at master · FreeFem/FreeFem-sources · GitHub](https://github.com/FreeFem/FreeFem-sources/blob/master/examples/hpddm/laplace-adapt-dist-3d-PETSc.edp)) and visualize with paraview.
