I now get a running error when I run the solver buoyantBoussinesqSimpleFoam - I am still relatively new to OF and I am sure the error lies in case files - maybe. Or it is due to my limited computer resources - I intend to run the simulation from starttime 0 to endtime 100 whereby delta t is 0.25 at a write interval of 4 - I am sure this corresponds to a courant number <1 for my case
I receive the following error at 6 seconds into the sim - always at 6 seconds:

Time = 6

- Any pointers into what is wrong?
