Write Exodus with add_polygonal_regions in 1.4

[lijingwang]

Dear all,

There is a problem when I try to add a subcatchment to calculate the discharge in the new watersheds workflow 1.4 version. I added my region using

watershed_workflow.regions.add_polygonal_regions(m2, subcatchment, volume = True)

And this adds 'CELL' to the m2. In the previous 1.3 version, it adds 'FACE' to the m2. Q1: Why CELL here?

Second, when we add this region and do the extrusion, the final m3.write_exodus doesn't work because the exodus can not deal with the CELL/elem_set. I think there is a warning comment.

Q2: If we change from FACE to CELL, we can not really write CELL/elem_set in exodus, then we can not make this mesh work. Any suggestions?

Thank you very much!
