FAQ
ParticipantThe memory problem encountered by CFX is rare, likely due to the large problem size. Memory errors in CFX are typically generated in the Partitioning, Interpolation, or Solver sections. This occurred at the end of the CCL section prior to partitioning. The issue here was not enough memory for CCL. There is a memory size allocation for this, –sizeccl. There are no error diagnostics available to determine that this memory factor is required, other than CFX failing at this location (end of CCL section).
