Hey, I used Version 5.4 for a time-dependent thermal stress simulation in a 2D-space. Now I want to evaluate the results. For this I want to take some individual points of the 2D-model and want to plot these points in a diagram, which represent the temperature and the time for every point. Can anybody help please?

Hi,

For this purpose, use a 1D Plot Group with Point Graph subnodes, where you plot the temperature versus time. You can use points for the plot in two different ways:

  • Use existing points in the 2D geometry. For that purpose, you can add extra points as separate Point features inside the 2D domain. It is then sufficient with one Point Graph subnode, where you select the points of interest.
  • Use Cut Point 2D datasets to create point data at points in the geometry that you define in the dataset's Settings window. You can use multiple Cut Point 2D datasets where a single point is defined using coordinates and plot them in the same plot using corresponding Point Graph subnodes, each pointing to a separate dataset. You can also define multiple points in a single dataset as a grid or as data from a file.

Best regards,
