Hello all,
BC.png In my sketch, A is the value of the boundary face center, B is the value of the boundary cell center and C is the value of the center of the opposite face. As far as I know, zeroGradient BC is 1st order, A=B. My Question is how to apply a 2nd-order zeroGradient BC, which means 3A=4B-C (Or something else if not uniform) ? Thanks. |
