Moving mesh and GEOMETRIC CONSERVATION LAW
Dear developer,
In the SU2 code for the moving mesh, is there GEOMETRIC CONSERVATION LAW used to do the simulation with the moving mesh? In the source code, I can not find the subroutines on this topic? In addition in the previous version of the SU2, I found that the source code has the TORSIONAL_SPRING and ALGEBRAIC method for the deformation of the volumetric grid. But from v2.0.5, the TORSIONAL_SPRING and ALGEBRAIC method have been deleted. Could you please tell me if there are some reconsideration for those abilities or others for viscous flow with large amplitude flutter or aeroelasticity on RANS equations. Thank you! |

At the moment, GCL has not yet been implemented for the deforming mesh option, but this feature will be added in the near future as we update things for the V3.0 release. In fact, many improvements to the dynamic mesh capabilities are under development in the code, and they should be available for V3.0. Quote:
We have removed the TORSIONAL_SPRING and ALGEBRAIC options in favor of a new, much more robust, technique based on the linear elasticity equations. We have used it successfully for RANS shape design problems as well as some preliminary deforming mesh simulations. You can select this mesh deformation method with the FEA option for the GRID_DEFORM_METHOD. All the best, Tom |
Hi Jianming,
Just to follow up on this topic too: we have made more progress in simulating (and designing in) unsteady flows on dynamic grids, including the addition of a GCL. Please see the routine CEulerSolver::SetResidual_DualTime(CGeometry *geometry, CSolver **solver_container, CConfig *config, unsigned short iRKStep, unsigned short iMesh, unsigned short RunTime_EqSystem) in the file solver_direct_mean.cpp to find more details on the GCL implementation. Cheers, Tom |
Dear Tom, thank you. It is a very great news for me. Thank you for your great jobs.
