My feeling is that [[1., 5.]] shoud be equivalent to [[[1., 0.], [0., 5.]]]. I'm not sure why that isn't working correctly. > Sticking with the complete matrix form of the diffusion Coefficient > for Dx and Dz ( both similar functions of the cellVariable C) > > when I use this form > > TransientTerm() == DiffusionTerm([[[Dx,0],[0,Dz]]]) > > I get the following traceback error That's not surprising. Use a single FaceVariable or CellVariable of rank 2 for the diffusion coefficient. It's safer to do that for anisotropy. > I see questions posted on this list, Gist and stack overflow - is there a > preference for posting ? I prefer Stackoverflow, but depends on the nature of the question. Stackoverflow isn't good for very open ended questions or conversations. -- Daniel Wheeler _______________________________________________ fipy mailing list fipy@nist.gov http://www.ctcms.nist.gov/fipy [ NIST internal ONLY: https://email.nist.gov/mailman/listinfo/fipy ]
