Samuel Twain New Member samuel Join Date: Oct 2019 Posts: 15 Rep Power: 7	Dear all: I noticed that for a boundary condition class (e.g. fixedValueFvPatchField ), it has member functions: valueInternalCoeffs, valueBoundaryCoeffs, gradientInternalCoeffs() and gradientBoundaryCoeffs() which can be found from line 115 to 159 (https://cpp.openfoam.org/v7/fixedVal...8C_source.html). I have known that when matrix is solved, boundaryCoeffs() and internalCoeffs() will be add to matrix coefficients or source. So are these above member functions uesd to calculate boundaryCoeffs() and internalCoeffs()? Waiting for your reply sincerely. samuel Last edited by Samuel Twain; November 1, 2019 at 05:19.
