Open the Examples project and open Case 2.

 

 

General Tab

 

 

To edit the general model data either click on the General tab. On the General tab the Title, Number of Layers, Maximum Depth, Darcy velocity, and Laplace Transform parameters can be specified.. In this example there will only be one layer and since it is for diffusion only the Darcy velocity is zero.

 

The times and depths to calculate the concentrations can be specified in the Run Parameters at the bottom of the tab. IIn this example, the concentrations will be calculated at 5 times: 10, 50, 100, 150, and 200 years.

 

 

Layers Tab

 

 

The data for the layer can be specified on the Layer tab. In this example, the diffusion coefficient of 0.01 is specified for the layer.

 

 

Boundaries Tab

 

 

The boundary conditions for the model can be specified on the Boundaries tab In this example, the top boundary has a constant concentration of 1 and the bottom boundary has a constant concentration of 0.
