Numerical models are programs that are separate from GMS that are used to run an analysis on a model. The models can be built in GMS, and then run through the numerical model program. GMS can then read in and display the results of the analysis.
GMS has the option of using a model wrapper to run the model and display real-time results of during the model simulation.
The following numerical models are currently supported in GMS.
3D Grid Models
Analytic Element Model
2D Mesh Models
