I am unable to click the Apply button in the ParaView window. I tried the cavity case again from scratch. I get the result before I click Apply button, though I haven't done the simulation beforehand. I uninstalled and reinstalled parafoam, but still, I'm not able to get the apply button for anything. For example, if I change the scale factor it's changing in real-time...before clicking 'Apply'. How do I fix this?
Does your terminal show any output while you open ParaView or after you've closed it? If so, please post a screenshot of the terminal with the error.
