Because flooding is always a transient simulation type you have to prepare the initial conditions first. Therefore it is necessary to define a seepage boundary condition at the nodes which describe the mine.

The example “fl0.zip” includes a structure (attribute type SICK) to set the boundary condition. Assign this structure to node layer 6 and 7.

Save the mesh and start the model checks with the item Calculation Model checking. Continue with running a steady state flow simulation with the item Calculation Steady state flow.

 

Model checks (step 1) and steady state flow parameters (step 2)

 

The results of the computation are shown in the figure below. You can create this vertical cross section using the plot batch file “cs.bpl” (archive “fl0.zip”).
