Hello, I hope you are doing well. As you know, there is a possibility to plot the internal and kinematic energy after finishing a simulation. Does anyone know how I can plot them in PrePoMax? ---

You can request it in history output - choose Element Output and the following variables: - ELSE - internal energy - ELKE - kinetic energy ---

ELKE - kinetic energy is not working after a Steady State Dynamics Analysis. Versions tested: 2.2.0 and 2.2.10. ---

Do you have an idea? Do you think you can have a look at the pmx file? Thank you. ---

The energy is written in the .dat file but PrePoMax will not read it correctly. I will have to update the .dat file reader to make it available in the GUI. ---

Hi, I managed to extract this data from the \*.dat file directly into Matlab which turned out to be even more convenient. Thank you. ---

I’ve noticed that ELKE is still not read from the .dat files by PrePoMax (regardless of the type of analysis). Any chance you could fix it ? ---

I have added support for kinetic energy in the Steady state dynamic step. ---

Thanks. Can it read ELKE from the results of `*DYNAMIC` steps too? ---

Yes, it also works for a dynamic step. ---

Great, I’ll check it later. ---

It is added in the v2.6.2 dev version, which is not yet public. ---

Is the problem solved?
