When I calculated the flux flowing into rock from tunnels in a mine, using the function"IfmGetFlowValueOfGroupIdAtCurrentTime(pDoc,0)".But when the tunnel head get higher, the flux will larger than the tunnel's total volume. Althrough hydraulic gradient become bigger, but it shouldn't make the tunnel head become a negative number,  I thinks there are some wrong with the data,but what's wrong? Does somebody know?

Are there other ways to calculate the flux? I get the nodes number of the border.
Hope someone help me.
Thanks!

The function you mention calculates fluxes at boundary conditions. If you have set a boundary condition around the tunnel, the amount of inflow is not limited to the amount of water in the tunnel.
