To generate the mesh using the default options:
- Select Mesh->Generate mesh. (or press <Ctrl>-g keys)
- A window appears showing the maximum element size. This is the general mesh size that will be used for meshing the whole model. Leave this default size unaltered and click OK.
- A meshing process window opens. Then another window appears with information about the mesh generated. Click View mesh to visualize the mesh.
Note that in the zone highlighted in next figure, the elements are smaller than in the rest of the model. This is because of the shape of the surface placed there. When all meshing preferences are set by default, as for this example, the RFAST surface mesher is used. In this way, geometrical entities are meshed hierarchically: first of all lines are meshed, then the surfaces, and finally the volumes. The line elements size depends on the shape of surfaces (as can be seen in this example). Later on we will see an example of how to SKIP ENTITIES in the meshing process, leading to a different element sizes distribution.
