#1: Visualizing Data
This tutorial will show how to create a simple grid and edit it. We will then specify (in independent order) the model's heterogeneous material properties, initial conditions, and time-dependent boundary conditions. Miscellaneous model parameters, such as simulation times and step size, error tolerances for the linear and nonlinear solvers, choices on solvers and quadrature method may be set through G3D sub-menu item Misc under the Edit menu item. The user may also read an existing G3D data set and edit it.
