How do I find equilibrium points of a partial differential equation?
$begingroup$
How do i find the critical points of this fourth order differential equation.
begin{equation} Dleft(frac{d^4w}{dx^4}+frac{d^4w}{dy^4}+frac{d^4w}{dz^4}right)+(rho_m-rho_c)gw=q-Pleft(frac{d^2w}{dx^2}+frac{d^2w}{dy^2}+frac{d^2w}{dz^2}right). label{bilaplaciano31} end{equation}
D, P, q, $rho_m$, $rho_c$, g are constants.
The boundary conditions are free.
Does anyone know how to get all the critical values for this problem? Thanks.

I solve the equation with finite differences placing a sinusoidal load distribution, obtaining an approximate solution. I also thought about finding the critical values of begin{equation} Dw''''+(rho_m-rho_c)gw=q-Pw''. label{bilaplaciano31} end{equation} overleaf.com/read/hcpnbdcqctdh to simplify the problem but I'm not sure if it's okay
