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.
