Pessure BC case
Hello everyone,
I have tried running my case with a pressure inlet BC, but it has just not even done the first iteration for past 15hrs. The same case runs fine with velocity specified inlet. I understand that pressure inlet is computationally complex. But what should i do to make my case run with a pressure inlet? Kindly reply asap. Thanks |
My simulation exited after 6 iterations. Saying "Floating point exception: overflow
any suggestions? |
Search the forum. Floating point error has been discussed zillions of times.
|
Could you describe your problem with some details. If possible please post some pics
|
Mine is a little complex internal flow system.
I tried the case with reduced relative total pressure at inlet, and the case is running. any suggestions pl.? |
As I said, this question has been asked a million times. I really shoudl write an FAQ on it one day.
Your simulation is numerically unstable. You need to improve the stability - improve mesh quality and smaller time steps (at least to start with) are the general approach to address it. |
will try reducing the time step n improving mesh
