I wanted to solve the following equation for T in OF. T is a scalar quantity.
div(c1*grad(T)) + div(c2*T) = div(c3)
This equation is expressed as the OF language:
fvm::laplacian(c1, T) + fvm::div(c2*T) == fvc::div(c3)
There is an compilation error on div(c2*T). Does OpenFOAM cover only two type of divergence terms: div(phi, T) and div(T)?
How can I deal with div(coeff*T)???
Thanks in advance for your comments.
First of all let's make sure I understand your problem: you want to solve a transport equation for a scalar field T with a diffusive term and a source term, right?
If so, c1 must be a scalar, but c2 and c3 must be vectors, otherwise you are trying to calculate the divergence of a scalar, which doesn't exisit.
Let's assume c2 is the vector transporting T, then this is a convection term that, if I'm not wrong, can be modeled in OpenFOAM with fvm::div(c2,T).
