GGU-ELASTIC: "Material (beams)" menu item
You can edit the characteristics of any beams defined. A dialog box appears with a number of input lines dependent on the number of beam materials selected.

The following designations are valid:
EJ = beam bending resistance
EF = beam elasticity coefficient
E = Young's modulus of beam
J = moment of inertia of beam
F = beam area
You can display a legend containing the material properties of any existing beams (EJ = beam bending stiffness, EF = beam tensile stiffness).
