An MRL Scenario

When you define a Model Resolution LengthOperation, only major portions of the model are retained in the mesh. An MRL example is shown in the following figure: 3 D symbols S and N are stamped on the top surface of the original geometry.

The following figures show the mesh plot without using Model Resolution Length Operation. The symbols S and N are magnified to show the mesh’s appearance when no model resolution lengthoperationis applied. These tiny indentations on the top surface are actually not significant for the simulation. Their presence results in a denser and bigger mesh of the model, especially in the tiny regions as shown below.

By defining a model resolution length operation, these tiny features or indentations can be removed from the mesh.

The following figure shows the mesh of the same model looks when you specify model resolution length. The mesh is coarse when compared to the previous mesh. Due to the model resolution length operation, the tetrahedrons representing the symbols for north pole and south pole have been removed.

Compare the figures and observe the difference between the meshes before and after the model resolution length operation.

The removal of extraneous features improves mesh quality and simulation efficiency and requires fewer computational resources.
