The licensing environment must be setup in the shell on all machines (Ansys Licensing). If the software is within an Ansys installation folder, and that Ansys installation was set-up with adequate licensing settings, the licensing settings of the installation folder will be used automatically.

The FENSAP-ICE license contains the maximum number of CPUs that can be used with MPI, and a number of seats (simultaneous job executions). For example: A single FENSAP license allowing the use of 16 CPUs can be used in MPI for one 16-CPU job, but cannot be used for two simultaneous 8-CPU jobs.

In order to run parallel Sweep operations in FENSAP or DROP3D, a sufficient number of software licenses is required. A 16-CPU DROP3D Langmuir sweep with 4 CPUs per job requires 4 DROP3D licenses (seats).
