Possible error sources are:
1) Paraview has not been installed correctly / link to the GUI has not been established correctly
Please make sure that Paraview has been installed correctly (either during the installation of Aspherix® or separatly) and that data for at least one write time step has been generated in this case. Then open the File/Options window and check the correct setting of the Paraview path:

(Installation location and version depend on your system and software version!)
2) No simulation data is available.
As long as the post folder of the simulation is empty, Paraview cannot be launched. Please launch the simulation, and wait until the first write_output_timestep is reached.
3) Missing system libraries on Linux based OS
For ParaView 5.12.x and 5.13.x we noticed that not all required libraries are shiped with the installer. Some operation systems (reported are Ubuntu 22.04 and 24.04) are missing system libraries by default - please install libqt5x11extras5 .
If you have sudo permissions simply run:
$ sudo apt install libqt5x11extras5
