How to use COMSOL functions (analytic) to define user-defined pressure force?

Hi,
I want to simulate deformation of a plate loaded with uniformly distrituted load (UDL). Till this point, it is fairly easy to perform the analysis. However, the plate is also acted upon by an external forcing agent which applies a load on botton surface of the plate as a pressure load. This pressure load is dependant of square of how much the plate is getting deformed because of the already applied UDL.
I am fairly certain that this can be achieved using COMSOL function (analytic) which will define this custom force acting on the plate. However I am not sure how to define this COMSOL function and use plate's deformation variable to properly define this forcing function.
I sincerely request you to guide me in this regard. Any prior example where a custom force is defined using COMSOL function (analytic) will also be helpful.
Regards,
Kedar
