Hi!

I am doing a nonlinear analysis of thin beams in mechanical APDL. For this, I would like to plot the maximum stress and strain over time through exporting the data over time. I am able to read it from the result viewer by hand but I need the data for parameter sweeps. The position of the internal stress changes over time. However, when I loop over all time steps and use the ETABLE command it says that the S label is not available. How could I solve that problem? Or is there perhaps an alternative method to get the internal maximum stress over time?

Thanks in advance!

To plot the maximum stress over time in APDL, you would need to extract the maximum stress at each time step and store it in an array for later plotting. This can be done using the *GET command in APDL, which can be used to extract the maximum stress in the element after performing a solution and creating a plot of stress. You can refer the below link.

Below is the link to how to use the GET command.

Hope this helps.
