Deformation of free surface under pressure– 2D model with surface tension

muriel carin, universite de bretagne sud

This model is concerned with the simulation of incompressible Newtonian fluid flow problems with surface tension. The fluid is initially at rest in a square tank. A Gaussian pressure is applied on the free surface which deformed the initially flat surface. This model is developed for a 2D transient analysis. The movement and deformation of the computational domain are accounted for by employing the Arbitrary Lagrangian-Eulerian (ALE) description of the fluid kinematics. The implementation of the model is detailled step by step in the pdf file for the version 3.5a.
To visualize the results, you need to solve the comsol file.

I cant seem to view any of the downloaded files. Anyone facing the same problem?

I have added the model built with the version 4.4.

Some mistakes were noted in these calculations. For example, there are no lines 5th and 6th in the tank geometry and they are applying weak constraints there. Dose some others observed?.
