3.3 Mesh generation
In GeoStudio all meshing is now fully automatic. There is no longer the ability to draw individual “finite
elements.” In addition, there is no worry whether the mesh will be compatible across different regions or
whether your material properties or boundary conditions will disappear if you change the mesh.
When a geometry region or line is initially drawn it is by default un-meshed. A default mesh is generated
for the soil regions when you first use the Draw Mesh Properties command, which you may accept or
modify. You may alter the size of the elements at a global level for the entire mesh, within any one or
more regions, or along a line or around a point. You may specify mesh density as a real length unit, as a
ratio of the global mesh size, or as the number of divisions along a line edge. Generally, however, it is
recommended that you limit altering the mesh to changing the global density and then, if necessary, at a
few limited locations where finer or coarser density is needed.
Meshing options and available patterns are shown in the image below.
