Summary0001262: codeStream
Descriptionthe codedFixedValue feature which is applicable for the applying custom boundary condition is not applicable for trigonometric functions.
I am trying to apply a transient profile at the inlet using codedFixedValue, but it seem to work only for ramping the BC. I want to apply a sine function.


Steps To Reproduceinlet
{
    type codedFixedValue;
    value uniform 0;
    redirectType ramp;
    code
    #{
        operator==(min(10, 0.1*this->db().time().value()));
    #};
}

Just use 'sin' as you would in any piece of code. E.g. based on the pipeCyclic case:

        code
        #{
            const vector axis(1, 0, 0);

            const scalar omega = 10;

            scalar s = sin(omega*this->db().time().value());

            vectorField v(2.0*this->patch().Cf() ^ axis);
            v.replace(vector::X, s);
            operator==(v);
        #};
