Everything in FiPy is Cartesian. > Is there a place to look at this function and how it is computed? Take a look at, https://github.com/usnistgov/fipy/blob/develop/fipy/variables/cellVariable.py#L257 https://github.com/usnistgov/fipy/blob/develop/fipy/variables/cellVariable.py#L270 https://github.com/usnistgov/fipy/blob/develop/fipy/variables/gaussCellGradVariable.py#L105 https://github.com/usnistgov/fipy/blob/develop/fipy/variables/faceGradContributionsVariable.py#L80 It's just the standard FV formulation. Hope that helps. -- Daniel Wheeler _______________________________________________ fipy mailing list [email protected] http://www.ctcms.nist.gov/fipy [ NIST internal ONLY: https://email.nist.gov/mailman/listinfo/fipy ]
