Models with 2 or more subsystems do not compile

Question

When I try to compile a model with only one SM subsystem, compilation works fine. However, when I try to compile a model with at least 2 subsystems, I get the following error :

-------------------- Starting compilation --------------------

This is because there is one feature missing in your license file (MULTIPROC). Please contact support (support@opal-rt.com) to get an updated license.
