PDE for Modeling Liquid Interfaces

Hello!

I would appreciate some help, as I am trying to solve a partial differential equation of a type I have not worked with before. This PDE models the boundary of a liquid as a radius, , which is a function of the 2D plate the liquid is "sitting" on, such that :

where and are constants. The plate is bounded at the ends by circular plates such that .

It is my understanding that this equation cannot be put into divergence form, which is required by the Coefficient Form PDE interface. As such, I am wondering if there is another COMSOL interface which is best equipped to solve this kind of PDE or if there is another way to still use Coefficient Form PDE.

Thank you in advance for any assistance.
