Hello, I have an equation of the form:
nabla.(D grad (phi)) = exp(a*phi - K) - exp(-(b*phi - K)) The diffusion coefficient is simply 'D'. But how do I cast the non-linear source term? i.e. what is the syntax to use in the code? In the examples, I did not notice any non-linear source term. 'a' and 'b' are just scalar coefficients of the CellVariable 'phi' in the source term. 'K' is a CellVariable of another PDE, which couples this PDE. Is it enough to simply write the source term as, ImplicitSourceTerm(coeff = numerix.exp(a*phi - K) - numerix.exp(-(b*phi - K)) Best Regards Krishna
