Hi all,

I am new to OpenFoam, and I have a problem with the implementation of the boundary condition.

The model I am trying to implement is composed of two rotating bicycle wheels. In order to model the rotation of the wheels, I wrote a customised boundary condition using CodedFixedValue. Here is the following code implemented in the U file of the 0 folder :

code

#{
const vectorField& Cf = patch().Cf();
vectorField& field = *this;

const scalar x_av = 0.370607;
const scalar z_av = 0.478752;
const scalar R = 0.36;
const scalar V = 18;

forAll(Cf, faceI)
{
field[faceI] = vector(-V*(boundaryPatch.Cf()[faceI].z()-z_av)/R, 0, -V*(boundaryPatch.Cf()[faceI].x()-x_av)/R);
}

#};

The problem is that, when I run the simulation, the following error appears :

After a few hours trying to figure out the problem, the only things I can tell about this error is that the .so file associated with the customised boundary file cannot be loaded, and maybe because OF does not acces to the .C and .H files of the src folder (I am not sure at all about that).

Thank you for your help, I hope I have given enough information to enable you to find a solution !

Kind regards
