I'm trying to find non-dimensional free vibration frequencies of plate, but COMSOL gives dimensional frequency.
(d^2u/dx^2+d^2u/dy^2+d^2v/dxdy=f1, d^2v/dx^2+d^2v/dy^2+d^2u/dxdy=f2). I'm trying to solve the mentioned coupled PDEs with Matlab toolbox. I don't know how to specify the coefficients for the...
