Use msengine
You can specify one or more of the following options after the input directory name:
• –i input_dir—Specifies the location of the directory containing the engine input files.
• –w working_dir1;working_dir2;...—Specifies the location of the directory or directories in which the engine places temporary files during the run.
• –solram ram_size—Specifies the amount, in megabytes, of memory to be allocated for direct solver memory and for element data for the iterative solver.
• –iter n—Specifies that the engine uses the iterative solver after polynomial pass n, a number from 1 to 8.
• –sturm option—Specifies whether or not the Structure engine performs a Sturm sequence test for a modal analysis.
• –extopt—Specifies that Creo Simulate uses an external optimizer to run either a function evaluation (using a standard study) or a gradient evaluation (using a local sensitivity study).
• –ascii—Specifies that the engine writes the engine output files in ASCII format.
• –p password—Specifies an optional password.
• –bsram ram_size—Specifies the amount, in megabytes, of block solver RAM the engine uses for equation solving.
• –elram ram_size—Specifies the amount, in megabytes, of RAM available to store element matrices created by the iterative solver.
• –massnorm—Specifies that the Structure engine mass-normalizes mode shape vectors instead of unit-normalizing them in modal analysis.
• –no_supercon_recovery—Suppresses superconvergent stress recovery.
• –contact_penetration pen_percent—Specifies the allowable penetration percentage for contact analyses.
• –results_io_cache_size <size>—Specifies the size of the results IO cache.
• –results_always—Forces postprocessing during SPA pass 1 in an analysis.
• –pmax n—Specifies the maximum p-order in a transient thermal analysis.
• –no_pert—Suppresses perturbation solvers.
• –asm_elm_fix_p_order_off—Fixes the p-order in assembly elements.
• –sim_accurate_asm_links—Forces assembly link calculations to take into account the separation of linked shells.
