interFoam - pressure explosion due to unknown reason

aquamen · June 4, 2015, 04:18

Hey Guys,

My Simulation aborts before it ends with an undescribed ERROR.
After checking the Results, i found out, that a pressure"explosion" could be the reason. Does anyone of you know where this comes from??

Thanks for your help

hi there;

May be you can describe more about your case. I guess you are using someting like an interFoam solver?

Maybe your pressure might not be the reason. It is difficult to say unless you provide the conditions you are using.

But a best and simple way to know if you have an error is to proceed step wise from the available code and later modifying it step by step.

hope this helps;

Hi
the easiest way is I give my Simulationparts.

You find it in the Attachments.

Please simulate it, and may you can tell me the problem for the Error.

Or even take a look on the files.

Thanks a lot

i'm not sure about that.

but do wallfunctions work with a zeroGradient in velocity? i don't know your case, but these parts should get inletoutlet at k and epsilon or a fixedvalue (0 0 0) in the U file.
