The MAESTRO Fine Mesh module allows the user to create refined 3-D FEA models of any portion of the MAESTRO model quickly. The user creates a group made up of elements from the "area of interest" then refines the group based on two options. The first option being the Top-down mode. In this mode, Fine Mesh Analysis applies displacements from the global analysis to the fine mesh model for boundary conditions. In the Embedded mode (the second option), Fine Mesh Analysis replaces the coarse mesh portion of the model with the fine mesh.
