In Femap, it's possible to extrude element edges to create new shell elements. This is useful when there is no geometry or other edge surfaces available.
To extrude element edges, select Mesh > Extrude > Element Face in the menu, and click the Multiple button in the Select Element Faces dialog. In the subsequent entity Selection Dialog, click Select All and OK. In this example we're going to select all the elements of a plate, as it’s the plate edges that are to be extruded. In the Face Selection dialogue, select Adjacent Faces and set the tolerance to be greater than the corner angles of the perimeter; in this case, anything greater than 90 degrees. Then select one of the edges.
Click OK, and you should see the Select Element Faces dialog with the list of edges to extrude.
Click OK to accept the selection. In the Generation Options dialog, click the Advanced >> button. Next, define the method and direction of extrusion, distance to extrude, and the number of elements to cover that distance.
Click OK, and you can finally see the new wall elements extruded from the original element edges in one single command.
