Cross Section Mesh Using V05 Geologic Framework Model with modification to reduce the dip of the steam cap in the western portion of the model. The top of the model is flat with a constant elevation of y=1100m. The two dimensional mesh has been extruded to create a 2.5 dimensional tetrahedral mesh. The extruded mesh has nodes at z=0, +-100, +-300, +- 600, +-1000.
Dimension:	Three Dimensional
Grid Element Type:	Quadtree Refined Triangles Extruded To 2.5D Tetrahedra
Grid Software Used:	LaGriT and Gridder
