*NOFC
By default the solver will make a memory estimate at the beginning of the simulation process to determine if the available RAM is sufficient to solve the problem. If the RAM is not sufficient, the solver will enable *OFC2 and *OFC3 to write matricies to Direct Access Files. To override this and to directly turn on or off the off-core pre-processing cards *OFC1, *OFC2, and *OFC3, the *NOFC card is required.
