There are two ways to generate the finite element mesh in RAM Concept :

• Using the automatic meshing facility, described in Generating the Mesh , that uses the mesh input objects, described in Defining the Structure .
• Using the manual meshing tools described in this chapter.

The first method is certainly easier and faster. It is the recommended method for nearly all models.

The second method allows more control over mesh intensity: the mesh size can be more widely varied in different areas of the floor. The method is, however, more prone to user error and editing is more difficult.

Do not use the manual method to supplement a mesh made with the automatic meshing facility. This is because manual elements would be lost if you used the mesh generation facility. For example, if you added a column element above in the element layer it would be lost when you regenerated.
