Plot the change of a variable over the whole simulation time in one point

Please login with a confirmed email address before reporting spam

Hey guys,

I have an easy problem, buts its hard for me to solve...

I want to plot then change of a variable (temperature, pressure and so on...) over the whole simulation time in one specific point of my choice of my geometry.

The problem is to tell Comsol, which specific point I likte to have. How can I do this?
Without any problems it is possible to plot the status of all points for a specific timepoint. I do not want to though. Can someone help me there?

Greetings

Hi

either the point, line, boundary exist, and you can integrate or average over this element in a derived variable, that makes a table over time, and then you plot that

if the element does not already exist in the geometry, you need to make a derived data set (point, line cut plane ...) from the solution data set and then plot there on

Good luck
