The error “not enough memory…” was common for the old 32 bit version of SOFiSTiK. Back then windows had some constraints when working with larger systems.
Nowadays with the 64 bit version this shouldn’t be a problem any more. So I would advise to update the program to the latest service pack.
Perhaps you check out the post from April 2020.
@sfr In ELLA the M-parameter is still used for allocating memory before the start of the calculation.
