Hi all, I’m working on implementing a rather simple thermal diffusion model with FiPy, but haven’t been able to find any examples or things in the docs to get me over the last challenge.
The model represents a stack of several materials. One of them is a granular substance that is sheared and generates some heat. The shear heating generation is just the product of the shear stress and velocity. The velocity will vary with time in the model (in the end). Basically I’m solving equations 2,3 from http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.211.384&rep=rep1&type=pdf <http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.211.384&rep=rep1&type=pdf> I was able to build the model and solve a simple diffusion problem, but I’m having trouble figuring out how to get the heat generation term into FiPy. You can see the simple notebook and a notebook in which I tried to add the heating terms on this gist: https://gist.github.com/jrleeman/8bcafffd512feaa77ec2946dc92460ae <https://gist.github.com/jrleeman/8bcafffd512feaa77ec2946dc92460ae> I’m probably missing something, but after looking through the source term docs I was unclear how to proceed. Many Thanks, John
