DEFINE_INIT UDF Call during Initialization

When is a DEFINE_INIT User-Defined Function called in Ansys Fluent?

The INIT UDF is called after standard or hybrid initialization on host and node processes.

For older versions of Ansys Fluent (prior to 18.2) it was only called on the node processes.

Since a FMG initialization requires a solution initialization the prescribed initialization through a INIT UDF will be accounted automatically.
