I have a new installation (FEMAP 11.2 & NX 10.1 on a Windows 8.1 m/c) but cannot get any of my analyses to run. Nastran crashes in the SEKRRS module regardless of the solution sequence run. The f06 file error is...
MAIN: "Illegal instruction" (C000001D) exception encountered.
MAIN: For reference, A(MAINAL) = 7FF763CD1090, A(/SYSTEM/) = 7FF76677EB20
MAIN: A(/OPENZZ/) = 7FFF1040
MAIN: Exception occurred at address 00007FFAF9CB3E72.
MAIN: Context Flags 0010005F
While a memory overflow seems likely, the decomp stats in the f04 are ...
CPU TIME ESTIMATE = 18 SEC I/O TIME ESTIMATE = 0 SEC
MINIMUM MEMORY REQUIREMENT = 1802 K WORDS MEMORY AVAILABLE = 501830 K WORDS
MEMORY REQR'D TO AVOID SPILL = 3631 K WORDS MEMORY USED BY METIS = 2309 K WORDS
...which indicates there is plenty of memory available. Any suggestions please?
Nastran is picking up the METIS method for matrix decomposition. Try selecting the BEND method. You can do this by setting the system cell 206 to 4.
You can do this by specifying "sys206=4" in the nastran command line option.
Further to the earlier post, failed job files are attached.
Watching the task manager while the job is running, the job fails when the process (analysis.exe) gets up to about 500Mb. The static job that runs with the GPU - the process grabs over 700Mb OK.
