For element ( e ): [ U_e = \frac12 \int_0^L \left( EA \varepsilon^2 + EI \kappa^2 + GA_s \gamma^2 \right) dx ] where ( \varepsilon ) = axial strain, ( \kappa ) = curvature, ( \gamma ) = shear strain, ( A ) = cross-sectional area, ( I ) = moment of inertia, ( E ) = Young’s modulus, ( G ) = shear modulus, ( A_s ) = shear correction factor.
Absolutely. If you want to move beyond downloading scripts, learning to write your own FE Snake Script is an excellent introduction to game hacking. FE Snake Script
Consistent mass matrix ( \mathbfM_e ) is used for dynamics, integrated via 2-point Gauss quadrature. For element ( e ): [ U_e =
This is where many novice scripts fail. The script must check: Consistent mass matrix ( \mathbfM_e ) is used
