continuously encountering divergence errors in Pressure coupled

Rohitah · June 8, 2014, 19:10

Hi,
I am trying to simulate the coolant flow in the water jacket of the engine using the settings Eulerian, multiphase, boiling, RIP, coupled scheme, Mass flow at inlet.
But I am continuously encountering with the divergence errors in Pressure coupled.

Please help me guys to get rid of it and suggestions are very much appreciated.
Thank you in advance...

same issue with me...just try reducing under relaxation factor & courant number...in my case it didnt work

Hello,

Are you running fluent in parallel mode? If yes, try some other partitioning methods.
In past, I faced similar problem. I reduced URFs and ran the case with lesser computing nodes..It worked for me..

Thanks
