      Question 1: If more memory is needed for the database than specified by the -db switch, does ANSYS create a page file? Answer 1: Yes Question 2: If more memory is needed for the solution then specified by the -m switch, does the dynamic memory manager use all of the remaining available memory? Answer 2: No, the dynamic memory manager only grabs as much memory as ANSYS needs. Question 3: Does the -m switch allocate only contiguous memory on WINDOWS platforms? Answer 3: Yes, however the total memory allocated will increase beyond the initial allocation, unless the -f option is specified Question 4: Will the -m switch allocate noncontiguous memory on UNIX platforms? Answer 4: No, the -m switch always allocates contiguous memory. Question 5: If the -m switch requests more contiguous memory than is available, does ANSYS fail? Answer 5: Yes, on both WINDOWS and UNIX platforms, ANSYS will fail with the following error message. **** FATAL **** The memory (-m) size requested is not currently available. Reenter ANSYS command line with less memory requested.
