We are working with a customer that uses MSC NASTRAN 2017.
A simple test model with Super Elements is accepted by NX NASTRAN 12.0.2 but then crashes with
MAIN: "Access violation" (C0000005) exception encountered. MAIN: For reference, A(MAINAL) = 7FF698231090, A(/SYSTEM/) = 7FF69BD8A400 MAIN: A(/OPENZZ/) = 1DD6C02D040 MAIN: Exception occurred at address 00007FF698D9BF40.
