Derived Quantities in Paraview
 
Hi

I am using Paraview with SU2. Now the problem I face is that SU2 outputs 'conservative vector' instead of 'primitive vector (rho, u,v, w, pressure) in paraview(vtk) file it dumps. Is there any simpler way to get 'primitve variable' using the formula we usually use.

Meaning can I derive 'primitive variable' from the 'conservative variable' and plot in paraview.

Thanks

You can use the calculator filter:

Code:
rho = Conservative_1
U =(Conservative_2*iHat+Conservative_3*jHat+Conservative_4*kHat)/Conservative_1
I think pressure and temperature are already available.

Regards,
Tom
