Comsol: Global Variables Plot Time Resolution

[georg]

Hi everybody,
I've got a problem with the Global Variables Plot in a 3D thermo-structural problem. I want to plot the reaction force for all the stored output times, but the interpolation only takes 7 steps of the solution, although the "times" in my time stepping are 0:.01:10 .
In my opinion the problem is anything with the solver manager, but I'm not sure. Could somebody please give me a hint? Thx!

Problem solved...
In the "solve parameters", the chart "Time Stepping" ,then "Time steps taken by solver", I had the setting "free" which was not such a good idea. Works much better with "strict".

Hi there,

It is possible that the issue you are experiencing with the Global Variables Plot in your 3D thermo-structural problem is related to the solver manager. One potential solution could be to adjust the solver settings to increase the number of output times that are stored and used for interpolation. This can usually be done by adjusting the time resolution or time step size in the solver settings.

Another possibility is that there may be an error in your time stepping or interpolation settings. I would recommend checking these settings carefully to ensure that they are correctly specified and that all necessary output times are being stored.

If the issue persists, it may be helpful to consult with the technical support team for Comsol or to seek assistance from other experienced users on online forums or communities. They may be able to provide more specific guidance or troubleshooting steps based on their own experiences with similar problems.

Best of luck with resolving this issue.
