. Select Mesh->Reset mesh data to reset all mesh sizes introduced previously.. A window appears advising that all the mesh information is going to be erased. Press Ok.. Go to Utilities and open Preferences and select Meshing card. . First Reset preferences, and then select RJump mesher. Click Accept. . Select Mesh->Generate Mesh.. A window opens asking if the previous mesh should be eliminated. Click Yes.. Another window appears in which you can enter a maximum element size. Leave the default value unaltered and click OK. This results in a mesh where contact lines between surfaces that are tangent enough do not have nodes; contact points between lines tangent enough are also skipped when meshing (see Figure 11).
Note that the smaller elements shown in Figure 3 do not appear in this mesh, because of the properties this mesher.Using the RJump mesher it is possible to assign sizes to different entities. As an example, select Mesh->Unstructured->Sizes by chordal error….
. In the window enter 0.05 as chordal error.. Enter 10 as maximum meshing size and 0.1 as minimum meshing size.. Press OK.. Again, select Mesh->Generate Mesh.. A window opens asking if the previous mesh should be eliminated. Click Yes.. Another window appears in which you can enter a maximum element size. Leave the default value unaltered and click OK. This results in a high concentration of elements in curved areas, without the nodes in the lines and points that mesher skips. Now our approximation is significantly improved (see Figure 12).
