- in makeFaMesh, the serial fields are now only read on the master process and broadcast to the other ranks. The read+distribute is almost identical to that used in redistributePar, except that in this case entire fields are sent and not a zero-sized subset. - improved internal faMesh checking for files so that the TryNew method works with distributed roots.

Description
|
|
A mesh generator for finiteArea mesh.
|
|
When called in parallel, it will also try to act like decomposePar,
|
|
create procAddressing and decompose serial finite-area fields.
