Information
Simple supported beam equation
Implements the simple supported beam equation
The initial conditions are
and boundary conditions are
Because the integrator block cannot accept the equation in this form, we transform the PDE above into two first-order PDEs:
The first equation is implemented in v block, the second in w block.
The analytical solution of this problem is implemented in SSBAnalytic block.
