Analyst supports several levels of control over the discretization of the initial mesh.
Global controls over the meshing process can be set through controls on the mesher itself. For further discussion see “Initial Meshing”.
Control over the meshing process on an individual solid can be set through the meshing parameters of the solid. For further discussion, see “Solid Meshing Controls”.
Local control over the initial mesh on an edge, face, or body of a solid can be set by applying a mesh constraint on the edge, face, or body. By using mesh constraints, you can control the size of elements (triangles, tetrahedra) affected by your chosen edge, face, or body. You can control the degree of accuracy with which the mesh represents curved edges, faces, or bodies on which the constraint is applied. You can also scale affected elements anisotropically in any combination of directions. For examples of two ways of using mesh constraints on a body, see “Local Control Using Mesh Constraints” and “Local Control Using Overlapping Solids”.
Recommended Approach: Control over the initial mesh on a sub-volume of a solid can be set by specifying mesh properties locally as described in “Local Control Using "Mesh Control" Solids”. In many situations this method can simplify geometric construction while allowing you more granular control over your initial mesh than may be possible by the use the methods mentioned above.
