- Auto
- default setting
- the necessary memory is estimated, then compared to the physical ram available. If enough RAM is available, the analysis runs in GUI process. If not, it is shelled out to CSI.SAPFire.Driver.exe.
Parallel Load Case Options:
- If the Analysis Process option is set to “Separate Process”, it is possible to run up to eight load cases in parallel and significantly reduce the total analysis time for models with many long-running load cases.
- Running multiple load cases in parallel puts a higher demand on system resources (e.g. memory, CPU, and disk) than running them sequentially, and can slow down other tasks running on the system, hence is best for fast, dedicated analysis machines.
- Running more load cases than the number of physical cores in parallel generally does not speed up the analysis, hence is not recommended.
Other Options:
- Always run 32-bit analysis
- only applies to Separate Process (and Auto when it shells out the analysis), which is run in GUI Process when the 32-bit version is used
- on a 64-bit system (64-bit CPU and 64-bit OS), 64-bit analysis runs by default when shelled out, and the option must be checked to run the 32-bit version
- forcing the 32-bit version is not advisable without reason since the 64-bit analysis version is faster and can solve larger problems
