2D Meshes can be created 3 different ways in GMS: using an automatic meshing technique, manually entering the node locations and triangulating, or converting a different GMS data type to a 2D Mesh.
Map → 2D Mesh is the preferred method for mesh generation in GMS.
In order to create a 2D Mesh in GMS there must be a set of 2D Mesh nodes. Elements can be created by using one of the Create Element tools in the 2D Mesh Tool Palette and then selecting the mesh nodes to create elements. A 2D Mesh can also be created by triangulating the nodes. The triangulation algorithm assumes that each of the vertices being triangulated is unique in the xy plane, i.e., no two points have the same xy location. Duplicate points can be removed by selecting Find Duplicates command from the Mesh menu. A prompt will ask to input a tolerance to be used when checking for duplicate nodes. Two nodes are considered to be duplicates if the XY distance between them is less than or equal to the specified tolerance. Also specify whether the duplicate nodes are to be deleted or simply displayed in red.
A 2D Mesh can be created manually from the following steps:
TINs, 2D grids, 2D scatter points, and 3D meshes can all be converted to a 2D Mesh. This is accomplished by using the following commands:
