Hi all,
I trying to simulating a simple geometry in 2D, and my boundary conditions are defined pressure in the inlet and outlet and velocity evaluated by this pressure difference. My problem is that I have to grow the difference of pressure very slow, because if I put a big difference of pressure with a initial field of velocity defined as zero, it does not converge. So, what I am doing is to set a small difference of pressure and as the flow is solved I am changing the difference of pressure. Anyway, what I am trying to do to avoid this work setting a "ramp" in the difference of pressure, using the BC timeVaryingMappedFixedValue.
The problem is that it is not working. I will put my BC here and I appreciate if you can help me on that!

So, my inlet and outlet files are:
for velocity:
inlet
{
type pressureInletVelocity;
value uniform (0 0 0);
}
outlet
{
type zeroGradient;
}


for pressure:
{
inlet
{
type timeVaryingMappedFixedValue;
fileName "ramp.dat";
outOfBounds clamp;
}
outlet
{
type fixedValue;
value uniform 0;


My ramp file:

(
(0.0, 0.001)
(0.1, 0.010)
(1.0, 0.100)
)

The error message is:

-> FOAM FATAL IO ERROR:

Thank you very much,
