Hi everyone,

I'm experiencing repeated failures with the CST Partial RLC Solver (2026, 2nd order) while simulating a relatively complex PCB using the 3DEXPERIENCE cloud platform.

The solver terminates with the following generic error:

Calculating reduced order model.
ERROR:
Solver:72: Terminated abnormally

The model contains approximately 1.8–2.5 million tetrahedra and up to 48 RLC node pairs. The issue occurs with both Adaptive Mesh Refinement enabled and disabled, typically during the Reduced Order Model calculation.

I suspect a possible memory or computational resource limitation, but the available logs do not provide any specific explanation.

Does anyone know how to obtain more detailed diagnostic information about this error, particularly when running on the 3DEXPERIENCE cloud platform, where direct access to server resources is not available?

Any suggestions would be appreciated.

Thanks!
