      A: The default Intel MPI library that gets installed at Ansys verison 2019R1 is version 2017.3.210. This has problems initiating a distributed parallel run. There is a newer version in the Ansys installation folders at “C:Program FilesANSYS Incv193commonfilesMPIIntel2018.3.210Windows”. Installing this version on all machines involved in the distributed run should fix the problem.
