# GMS:SEEP2D Solution

From XMS Wiki

Jump to navigationJump to search
After a SEEP2D simulation is run in GMS, the solution to this simulation can be automatically loaded into GMS. The solution will appear in the Project Explorer under the " 2D Mesh Data" folder in its own subfolder. The subfolder will appear with a lock image on it . The image means that the information in the solution folder is locked and cannot be edited from within GMS. The solution datasets in the solution can be contoured and viewed in GMS.

The potential datasets that may be part of a SEEP2D solution are listed below with a brief description.

- Total Head – The pressure head plus the elevation head (same as the head measured by a piezometer).
- Pressure Head – The water pressure divided by the unit weight of water.
- Pore Pressure – The hydrostatic pressure.
- Flowrate – The flow rate of water into (out of) the problem domain.
- Velocity – The discharge velocity is calculated by multiplying the gradient by hydraulic conductivity [k*i]. This is a vector dataset and is accompanied by a scalar dataset called "velocity_Mag" that is the magnitude of the vector dataset.
- Gradient – The hydraulic gradient is calculated by dividing the difference in Total Head by distance [(h
_{1}-h_{2})/L]. This is a vector dataset and is accompanied by a scalar dataset called "gradient_Mag" that is the magnitude of the vector dataset. - Flowline – This dataset is used to create a flow net when the Total Head dataset is the active dataset.

All dataset values are calculated at every node in the mesh.
