plotMPI, how to get plot display for parallelization hpddm

Thanks for your timely reply.

The installation package I used is:

The testing code I used is:
https://github.com/FreeFem/FreeFem-sources/blob/master/examples/hpddm/stokes-3d-io.edp#L99-L101

The command line:
ff-mpirun -np 4 stokes-3d-io.edp

And I noticed that besides a “.pvd” file, another 4 “.vtu” files have been also generated. Please check the attached .zip file.

In addition, I hope to know the extensibility of hpddm with regards to the adaptive mesh. Would it be possible to use hpddm if the mesh is updated based on level set function with the MMG3d tool. Please see the links: https://www.mmgtools.org/mmg-remesher-try-mmg/mmg-remesher-tutorials/mmg-remesher-mmg3d/mmg-remesher-implicit-domain-meshing
I have realized this updating process without parallelization. But if the hpddm can be integrated into the solver, it will be very helpful to speed up our optimization.
