SU2 Ship Hydrodynamics?
Is it possible to run a ship hydrodynamics problem with SU2?
This type of simulation can be performed by solving the level set equations. The most recent version (v2.0.2) contains many improvements on this. See the section titled "FREE SURFACE NUMERICAL METHOD DEFINITION" in the file trunk/config_template.cfg to see configuration options.
For a reference you may want to look at the following article:
Palacios, F., Jameson, A., Alonso, J. J., "Shape Sensitivity of Free-Surface Interfaces Using a Level Set Methodology," 30th AIAA Applied Aerodynamics Conference, AIAA Paper 2012-3341, New Orleans, LA, June 2012.
Thank you for your response. I have looked into the file that you have mentioned.
But my concern is a little bit different. According to the documentation provided by SU2 developers, SU2 is mainly a compressible code and its incompressible solver uses artificial compressibility formulation developed by Chorin to solve incompressible problems. However, Chorin's formulation is only valid for steady-state conditions. Because of that, although SU2 should be capable of simulating calm water resistance problems, I think it can not be used for seakeeping simulations which is highly transient.
Are there any new developments in the new version to improve that too?
Despite our main research application is optimal shape design (steady state regime), we are using a dual-time strategy (second order in time) to simulate unsteady two-phase problems. In other words, we fully converge an artificial compressibility problem at each physical time step.
On the other hand, thanks to the steady state convergence acceleration techniques of SU2, the artificial compressibility is efficient even solving unsteady problems.
We will update a tutorial to our web page in the near future.
