Hello,
In the weak formulation of my problem (a 2D diffusion problem), I have the term
\int_{\Gamma^N} p\nabla V\cdot M n
where \Gamma^N is region where Neumann BC is applied, p is a test function, V is the unknown function, M is a 2x2 matrix and n is the normal vector. Has an SfePy term been written corresponding to this?
Alternatively, is there a SfePy term corresponding to the integral
\int_{\Gamma^N} p\nabla V\cdot q,
where q is a vector? I saw the term dw_surface_lcouple, but it doesn't seem to support the weak evaluation mode.
Thanks,
Ben
