| real(kind=rk), | intent(in) | :: | state(4) |
State vector (as conservative variables). The order of this vector has to be where and denoted concentration (scalar) and diffusive fluxes (vector). |
||
| real(kind=rk), | intent(in) | :: | diffusivity |
The diffusivity in the cell. |
||
| real(kind=rk), | intent(out) | :: | flux(3) |
The flux inside the cell. The order of this vector is the same as the input arguments. |
