Hi
SU2 normally dumps paraview file with conservative variables. In case of compressible flow we can get the values of u,v,w, component of velocity using the filters with appropriate equation. Now my question is about in-compressible flow solution. I think the solution is based on preconditioning approach; (roe solver as flux). As per my knowledge for Wiess-Smith preconditioning the vector is lambda_matrix*transpose[p,u,v,w,t] . Now my question is what are the conservative variable in case of incompressible flow. How can I derive velocity components and magnitude from it. Thanks Apoorv |

The first "conservative" variable is the pressure (the naming is kept for simplicity and since you can think of it as density in the low Mach limit), the following ones are the momentums in each coordinate direction.
In the incompressible solver, the density is throughout set to 1.0, so the values in Conservative_2, ... are simply the velocities. You have to mutliply them with the reference velocity if you want to have dimensional values, of course. Regards, Ole |

Thanks for your reply. I think that you could maybe interested in the new SU2 IDS www.su2devsociety.org
Best, Francisco |
