share adaptive mesh from master app to sub app

[BoZeng1997]

I am trying to clone the adaptive mesh from master app to sub app. I have set the clone_master_app=true in block [Multiapps] for the sub app in the master.i file. What should I do for the [Mesh] block in sub.i? I tried leaving it empty or add the original mesh file as FileMesh to read. Either way returned with error: Use either FileMesh with an Exodus mesh file or FileMeshGenerator with an Exodus mesh file and with use_for_exodus_restart equal to true

Hi Bo, see the discussion here .

We have some basic capability in the level set module for doing this. Check out the tests here: https://github.com/idaholab/moose/tree/next/modules/level_set/test/tests/transfers/markers
