By using very large mesh, or profile data, the CFX solver may fails with the following error message, during memory allocation. +——————————————————————–+ | ERROR #333100180 has occurred in subroutine Out_MemPar. | | Message: | | | | The total number of words requested by partition 1 | | for the Character stack is : 2149735936 | | That exceeds the maximum of : 2147483648 | | supported by the flow solver. Please reduce the memory usage. | +——————————————————————–+ By default, the workspace allocation is limited by using 32-bits Integers. But big problems may need 64-bits as shown in the above error message. To increase to 64-bits, a “Large Problem” option can be used: – interactively in CFX-Solver, by selecting Large Problem option in the Run Definition tab, or in the Advanced Controls tabs (Partitioner, Solver, Interpolator) – by the running command cfx5solve with the option”-large” (or -part-large, -solver-large, -interp-large)
