Nucleate boiling
 
Hi, i am trying to re simulate the nucleate boiling model tutorial using my own 2d grid produced in gambit. Everything went fine till the steady state condition, but in transient (using RPI model) there is no heat transfer occuring between the wall and the fluid. Can anybody have any clue ?

RPI Boiling model
 
Hi, i have tried to resimulate the nucleate boiling tutorial with my own model (which is an exact copy of the original model in the tutorial). But on using my model in fluent, no heat transfer is happening between the wall and fluid. If there is some problem in the handling of boundary conditions in Gambit ?

Dear all Friend,
I'm working on simulation of subcooled boiling in Fluent Does anyone has the RPI UDF handy?
I was wondering if it is possible to send me the RPI UDF. my email is:

Thanks in advance for your attention.

Can u post your contour? If u did all step following the tutorial, please check your model. The wall and fluid should be one part. Hope this help.
