Dear FiPy community, I have a number of questions to you: 1.I have a dependent variable phi(x,y,t). Is it possible to solve the below type of equation for this variable: TransientTerm == DiffusionTerm_x + ConvectionTerm_x + DiffusionTerm_y + ConvectionTerm_y, where _x and _y mean the "working" component of the nabla operator. I have to note that the coefficients are really different functions for each direction (x and y). Besides, for generality of the problem, "y" is not a space coordinate, but rather a phasespace(impulse). 2.If the above is possible, could you give me a hint how to do it? In principle, I doubt to use anisotropic diffusion coefficient, besides how to split the components of the ConfectionTerm. 3.Is it possible to define the "Terms"(Diffusion, Convection) "by hands" using .getDivergence() and .getGrad() methods (using the desired component)? 4.Is it possible to supply the "Terms"(i.e. Diffusion) with exterior coefficients so that nabla operator was not applied to them? Thanks and Cheers, Igor.
