big models are so slow it is agonizing. SWX is aware of these issue and so far no joy. It has been going on for years. If you run large models a different code is the only answer so far.
Here are a few things that might help:
- Consider using the ‘Result Options’ functionality to limit the scope of saved result data to only what you need. Refer to Simulation Help > Analysis Background > Nonlinear Static Analysis > Result Options.
- Reduce the number of Degrees of Freedom (DOF) in your study by simplifying and being more selective about mesh refinement if possible. A larger global element size combined with additional localized mesh controls in critical areas can make a big difference.
- If you specified the ‘Discrete’ Fringe option for any of your plots, try changing it to the less resource-intensive ‘Continuous’ option. Refer to Simulation Help > Viewing Analysis Results > Processing Result Plots > Settings PropertyManager.
- In the properties of your study, set the Results folder to the fastest local drive that has sufficient free space. A fast SSD can help overcome certain performance bottlenecks that occur due to slower drive data read speeds.
- Whenever it is time for a hardware upgrade, consider high performance workstation CPUs with faster clock speeds instead of CPUs with a large number of cores. Note that sequential operations like reading large amounts of data benefit more from CPU clock speed than the availability of many cores.
