The cpus_weight_std, cpus_weight_xpl, and cpus_weight_cfd environment file variables can be used to distribute CPUs between analysis products for a co-simulation execution procedure (“Co-simulation execution procedure,” Section 3.6).

The portpool environment file variable specifies the range of TCP/UDP port numbers that represent the start and end value of port numbers to be used by the co-simulation execution procedure when establishing connections between the child processes (“Co-simulation execution procedure,” Section 3.6).

The gpu environment file variable can be used to activate GPGPU solver acceleration in Abaqus/Standard (“GPGPU direct solver acceleration,” Section 3.1).
