Square drop oscillation under surface tension – 2D axi-symmetric model

Muriel CARIN, universite de bretagne sud, France

This model is concerned with the simulation of incompressible Newtonian fluid flow problems with surface tension. An initially cubic drop of water is oscillating under surface tension forces. This model is developed for a 2D axi-symmetric 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. To visualize the solution, you need to solve the model (click the solve button).

Cool, your module make me begin to like comsol.

Hi this is a nice work ! Could you PS post the working 4.1+4.2 version.

Hi,

I followed the method defined in the paper but the solution did not converge. I am using 3.5 version. Unfortunately I could not open the comsol file as it is created by a later version may be 3.5a? Is it possible to save the file in older version?

Hi Øistein Wind-Willassen,

could you send the model for the version 4.2?

Thanks!!

It is really a wonderful work.

would you pls to give some detail on the weakform boundary condition?

why it is this form:

-nu_surf*r*uTr_test-nu_surf*u_test

By the way, if there is a wetting condition on the right point, how to deal with?

Thanks a lot!

The boundary condition form is due to the fact that a cylindrical coordinate system is used. Had a cartesian coordinate system been used, the expressions would have been:

-nu_surf * test(uTx)
-nu_surf * test(vTy)

Hope it helps.

I have a version for 4.1+4.2 working, but it comes without the pdf introduction.
