Hello everyone,

I am trying to set an inlet boundary condition depending on the overflow velocity. For this I use the type codedFixedValue in the file 0/U:


INLET
{
type codedFixedValue;

value uniform (0 0 0);
name rampedFixedValue;
{
#{
const scalar Sc = 1.0;
const scalar p_d = 101325;

[...]


vector u1 = readProbe("system/probes", 0, vector(0, 0, 0.001), "U");


scalar m_flow = 4.46e-3 * Foam:ow(Sc, -0.67) * Foam:ow(mag(u1), 0.78) * Foam:ow(r, -0.11) * (p_d * M * A / (R * T));


scalar U_mag = m_flow / (rho * A); // Setze U-Wert vector U_value = vector(0, 0, U_mag);



operator==(U_value);


#};
}
}

The size u1 is to be determined from the file system/probes at each time step.

system/probes


FoamFile
{
version 2.0;
format ascii;
class dictionary;
object probes;
}

// Probenposition über Patch LACHE in z=0.1 cm
fields
(
U
);

probeLocations
(
(0 0 0.001) // Koordinaten des Punktes über dem Patch LACHE in z=0,1 cm
);

// ************************************************** *********************** //


However, I receive the following error message:


--> FOAM FATAL IO ERROR:
Failed wmake "dynamicCode/rampedFixedValue/platforms/linux64GccDPInt32Opt/lib/librampedFixedValue_c0c0b359c41d0db4a18d7e5891c471 dca9c8315e.so" file: /home/X/OpenFOAM/X-12/run/SIM_5_codedFixedValue/0/U/boundaryField/INLET from line 55 to line 60.

I am using OpenFOAM version 12, do you have any ideas?

Thank you very much
