Hello,
I am stuck in how to correctly apply a simple convection boundary condition in FiPy, in the context of simple transient heat conduction in 2D. Is this correct: var.faceGrad.constrain([-convectionCoeff/k*(var.faceValue-T_infinity)]*mesh.faceNormals,where=surfaceFaces) I have a 2D mesh generated in gmsh. The convection boundary condition is applied to a curved boundary. The code and results are found at: https://github.com/cashTangoTangoCash/Convection2DFiPyExample01/tree/master The project appears to have a heap of files, but It’s a really just a simple 2D problem with a comparison to an analytical solution. The basic script is ConvectionTestProblem2D_01.py. Report20181116.pdf shows current results, which are clearly wrong. Am I correctly applying the convection boundary condition in terms of the FiPy syntax/language for this 2D problem with a gmsh mesh and a curved boundary? Thanks
