Hi all,

I'm trying to set a inlet pressure from a data curve of pressure and time. I use the OpenFoam v2.3.0 and I have seen the patch timeVaryingMappedFixedValueFvPatchField, but what little I understand about this patch is that it is necessary to create a folder for each time step within " constatn/boundaryData/inlet " and set the pressure value inside each time folder. Please, correct me if I'm wrong, I'm new in OpenFoam.

The point is I would like to know if there is the possibility to make that the pressure values are being read from a text file for example.

Regards.

Try to look at the T-junction tutorial
https://github.com/OpenCFD/OpenFOAM-...oam/t-junction

what they did is write the following in 0/p

inlet
{
//type totalPressure;
//p0 uniform 100040;
type timeVaryingTotalPressure;
p0 100040; // only used for restarts
outOfBounds clamp;

fileName "$FOAM_CASE/constant/p0vsTime";
U U;
phi phi;
rho none;
psi none;
gamma 1;
value uniform 100040;
}


and then create a file constant/p0vsTime which contains a table or list of the time vs pressure as following

(
( 0 100010)
( 1 100040)
)



now just like this you can make your file in the same listing way
and then put its path in 0/p

Hi Ali,

I didn't know that tutorial and I think it's what I'm looking for.

Thank you so much!

Hi,
I forgot it... I'm using OpenFoam v2.3.0 and the patch "timeVaryingUniformTotalPressure" is not in this version, it's in v1.7 only I think.
Could I implement this patch in my OF version in easy way?
Regards.
