Hi,

I am searching a way to set up an iteration-varying-BC. I want to ramp the inlet pressure linearly from X to Y Pa over the first 500 iteration steps. I found the timeVaryingUniformFixedValue - BC... but i don't want a change over time... can someone give me a hint?

My case is a steady one... so there is no time...

Thx

How come you want to vary the boundary condition in a steady simulation?

What solver are you using?

Did you trying using the time varying fixed value and just specifying the iteration you want where you would normally specify time?

So instead of the time put the iteration number. (Since to my knowledge the steady simulations still create "time steps" but they are whole numbers)

Heres a format for the time varying fixed inlet in a p file... you might be able to just change the time to iteration number... and then put the pressures you want. If you are lucky it could do what you want... it might be a dead end but you could try.

inlet
{
type uniformFixedValue;
uniformValue table
(
(0.0 53.82)
(0.0001 53.82)
(0.12 5382)
(0.1201 5382)
);
outOfBounds clamp;
value uniform 0;
}
