Hello,
is it possible to output results at a fixed time step in a transient simulation? e.g. from 1E-6 to 1E2 with 10 points evenly spaced on a log scale per decade. Or equally space on natural log scale.
Thanks,
You could use the time points feature for that. It’s not yet implemented in PrePoMax so you would have to add it via Keyword Editor. The syntax is described here: https://www.dhondt.de/ccx_2.22.pdf#subsection.7.133
After defining it, refer to its name in output request (also by editing keywords). For example:
*NODE FILE, TIME POINTS=...
how does one edit the output request? It will let me add a keyword but not edit the history output keyword.
I was able to get it to work. Not sure if it is the right way though. Creating a user keyword inside the history outputs and moving it before node print seems to work. The time points statement needs to be before the Steps section.
Back to back generate statements (one for each decade) didn’t seem to work. Only shows results for part of list of statements.
Had to do manual points.
Theoretically, multiple GENERATE sequences should work but manual list can indeed be a workaround. The rest seems to be correct - you have to add *TIME POINTS before *STEP and then create a new output request keyword with selected variables and references those time points within the step.
