Hi Foamers. I need a turbulent mass flow inlet for a time varying flow rate.
I tried to apply the following BC for a U profile (Solver:twoLiquidMixingFoam).
in
{
type turbulentInlet;
fluctuationScale (0.02 0.01 0.01);
referenceField flowRateInletVelocity;

massFlowRate table
(
( 0.0000000e+001 0.0000000e+000 )
( 0.0100000e+001 5.2890505e-003 )
( 0.050000e+001 1.0507891e-001 )
( 0.1030000e+001 1.5657144 )
( 0.2040000e+001 2.5737434 )
( 0.30000e+001 3.5749383 )
);
rho phase1;
rhoInlet 842.346;
}
No errors are generated starting the simulation, but seems as the inlet field does not feel the perturbation. Hierarchical errors?


In addiction I discover that using the csv data input as shown in the following BC
in
{
type flowRateInletVelocity;
massFlowRate csvFile;
csvFileCoeffs
{
fileName "FlowRate2.dat";
outOfBounds clamp;
hasHeaderLine false;
refColumn 0;
componentColumns (1);
}
rho phase1;
rhoInlet 842.346;

}
The simulation has no problem to start on 1 processor,

but if i try to run it on more than one processor (4 in this case) i obtain the following error:

Why??

P.S. Yeah, i would like to use swak4foam but i cannot being that i cannot update bison for admin reasons.
