It seems that parallel::distributed::SolutionTransfer does not support hp::DoFHandler, how can I transfer solution after mesh changed

[Jack]

Dear all,

 

I’m trying to using hp::DoFHandler to solve my problems. It seems that this type of dof handler does not work for solution transfer during parallel distributed computing. So is there any way to transfer solution after refining and coarsening of mesh when using hp::DoFHandler?

 

Many thanks!

 

Best,

 

Jack

Hi Jack,

The hp::DoFHandler does not work at all for distributed meshes (although I see that this is not explicitly stated in the class documentation or that of parallel::distributed::Triangulation). So you should never be able to attach a parallel::distributed::Triangulation to an hp::DoFHandler (see this line of code: have you run your program in debug mode?). You'll want to use the standard SolutionTransfer class with hp::DoFHandler.

I hope that this helps.

Regards,

Jean-Paul

Hi Jean-Paul,

Thanks for your help. My program failed to compile, so I didn't run it and get such an assertion.  I see that the un-supporting of hp::DoFHandler for parallel distributed calculation in hp namespace. 

Thanks!

Jack
