If you see that the script has a line "import ifm_contrib as ifm", this means
that it is not really using the standard IFM functionality. The script contains
a layer above named "contribution", which is a community extension. FEFLOW
standard IFM will give you all the arrays of results. These can be subsequently
used by any graphical Python packages for visualization and/or plotting such as
Matplotlib, PyVista, etc. You may want to visit our free self-paced course about
FEFLOW Python integration. I have few official examples how to plot FEFLOW's
results with Matplotlib. The link is below
