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
