Problem with a deposition equation
Hello everyone
i'm trying to make a solver that can solve this deposition equation
Fm*rod* d(r1)/dt = r1*Dw0* d(c)/dx
Being Fm, rod and Dw0 constants, and r1 and c variables defined in all the mesh
In my solver i use this
Code:
{
volVectorField gradienteC = fvc::grad(C);
volScalarField dcdx = gradienteC.component(0);
fvScalarMatrix depositionEqn
(
Fm * rod * fvm::ddt(r1)
- r1 * fvm::Sp(Dw0, dcdx)
);
depositionEqn.relax();
depositionEqn.solve();
}
It compiles well, but when i run it in my case this give me this error
Code:
--> FOAM FATAL ERROR:
incompatible fields for operation
[r1] - [grad(C).component(0)]
From function checkMethod(const fvMatrix<Type>&, const fvMatrix<Type>&)
in file /opt/openfoam231/src/finiteVolume/lnInclude/fvMatrix.C at line 1319.
If anyone could help me, i want to know if the equation is writed right in my solvers, and if there is any solution for this error
Would be very glad to get any help on this! Thanks in advance.
