Hello,

I have run two simulations with different mesh sizes from the “aachenbomb” tutorial on OpenFoam, and I would like to plot on the same graph, the curves of evolution of the liquid penetration distance versus time of these two simulations, how can I please proceed?

Plot Data over time should do the trick.

Thanks for your response.

In fact I can’t load the results of the two simulations on the plot data over time panel, only those of one simulation are available.

I can do it without any issue here.

thank you but It’s not what I need, I would like to plot on the same graph to curves of two different simulations.

I’m using two different sources, which is the same as two different “simulations”.

Please share what your are doing step by step, or a video, so we can help.
