Hello everybody,
I am simulating a cavity with a hole inside and with a fixedGradient for T on this hole surface (Laminar Flow). I made the mesh on gmsh, converted it to foam and then used buoyantBoussinesqPimpleFoam for the simulation.
However, after a bit the simulation ends with an error i have never seen in my short OF experience. I attach the log file, if you could give it a glance it would be enormously useful!
Thank you a lot!

Hey,

I just took a look at your logFile. As you can see your GAMGSolver is complaining with a floating point exception. But in fact the residuals of your pressure equation is not that high. However, you can take a look at the lines starting with smoothSolver. There you will clearly see that your residuals are on the order of e+158.

long story made short: your setup is not correct.

hi einstein_zee, thanks for your reply.
I noticed the huge residuals and i am trying to figure out in what the setup is incorrect, even though i am having some difficulties in finding out what's wrong
