WHILE THE MEMORY ESTIMATES ARE GENERALLY CONSERVATIVE, IT IS POSSIBLE THAT CERTAIN PROBLEMS WILL REQUIRE MORE MEMORY THAN THE MINIMUM ESTIMATE. IF THE ANALYSIS FAILS DUE TO INSUFFICIENT MEMORY, INCREASING THE VALUE OF standard_memory SHOULD ALLOW THE PROBLEM TO RUN. THE TABLE ABOVE PROVIDES A STEP BY STEP SUMMARY OF SOME BASIC SIZING INFORMATION FOR THE PROBLEM. SOME FURTHER DESCRIPTION OF THE PARAMETERS GIVEN FOLLOWS: (1) MAXIMUM DOF WAVEFRONT - SIZE OF THE BIGGEST FRONT IN THE EQUATION SOLVER. PROVIDES A BASIC SIZING OF THE MOST MEMORY INTENSIVE SEGMENT OF SOLVER. (2) FLOATING POINT OPERATIONS PER ITERATION - MEASURE OF THE NUMBER OF FLOATING POINT OPERATIONS REQUIRED FOR A SINGLE SOLVER PASS. ON A GIVEN PLATFORM THE TIME REQUIRED FOR A SOLVER PASS WILL BE ROUGHLY A LINEAR FUNCTION OF THIS VALUE. NOTE - EXCEPT FOR THE FIRST STEP, THE VALUE IN THIS TABLE DOES NOT INCLUDE ADDITIONAL FLOATING POINT OPERATIONS THAT ARE REQUIRED IN MULTIPLE LOAD CASE STEPS WHEN CONSTRAINTS CHANGE FROM LOAD CASE TO LOAD CASE. THIS SITUATION CAUSES A REORDERING TO BE PERFORMED, AT WHICH TIME AN UPPER BOUND ON THE NUMBER OF ADDITIONAL FLOATING POINT OPERATIONS WILL BE CALCULATED AND INCLUDED UNDER THE ESTIMATE SUMMARIES FOR THE RELEVANT STEPS (SEE NOTE BELOW ON REORDERING). (3) MINIMUM MEMORY REQUIRED - MINIMUM POSSIBLE MEMORY VALUE FOR standard_memory THAT ENABLES ABAQUS TO SOLVE THE PROBLEM. USE OF MEMORY WILL BE MINIMIZED BY WRITING AS MUCH INFORMATION AS POSSIBLE TO DISK WHICH WILL INCREASE I/O TIME. (4) MEMORY TO MINIMIZE I/O - VALUE OF standard_memory THAT ALLOWS ABAQUS TO KEEP ALL SIGNIFICANT SCRATCH FILES IN MEMORY. THIS WILL MINIMIZE I/O TIME FOR THE USER WITH ACCESS TO A LARGE AMOUNT OF MEMORY. (5) REQUIRED DISKSPACE - AMOUNT OF DISK REQUIRED FOR SCRATCH FILES. THESE WILL BE DELETED AT THE END OF THE ANALYSIS. NOTE - WHENEVER POSSIBLE THE USER SHOULD SET standard_memory TO BE LESS THAN THE PHYSICAL MEMORY ON THE MACHINE. UNLESS NECESSARY USERS SHOULD NOT MAKE USE OF VIRTUAL MEMORY EVEN IN AN ATTEMPT TO KEEP SCRATCH FILES IN MEMORY. NOTE - IF A REORDERING IS PERFORMED (THIS WILL ONLY GENERALLY BE DONE FOR FINITE- SLIDING CONTACT PROBLEMS), THE SIZE ESTIMATES DONE AT THIS TIME WILL NO LONGER BE VALID. THE ESTIMATES WILL BE REDONE IN THE EVENT OF A REORDERING AND A NEW SUMMARY WILL BE PRINTED FOR THE REMAINING STEPS.
