Hi Every One

I am trying to fix the pressure in domain using DEFINE_EXECUTE_AT_END macro for the journal bearing simulation.

Although I am able to solve it using the cavitation model along with mixture model, but there are some variables for which I don't have info, for example vaporization pressure...therefore I am preferring the first method...

Here is the UDF I am using (got it from this forum in some thread), but it is not fixing static pressure in domain as intended i.e. I want to make the static pressure at end of each iteration to zero...




Here are the results i am getting after each iteration (some random iteration)

It is working now . Thanks every one

hello,I am glad to know you success.Now, i am encountering the same difficult.Can you tell me how to change the negative pressure into zero?Thanks a lot!
DEFINE_ADJUST(adjust_pressure,domain)
{
Thread *t;
cell_t c;
thread_loop_c(t,domain)
{
begin_c_loop(c,t)
{
if(C_P(c, t) < 0)
{
C_P(c, t) = 0;
}
}
end_c_loop(c,t)
}
}
