Hi everyone,
I have successfully found a solution for my Mach 5 scramjet inlet and displayed the results in ParaView. I have values for temperature, density and pressure. I would like to calculate the enthalpy.
Is there an easy way to do so in ParaView using the calculator?
If not, can SU2 calculate the enthalpy?
Thanks!

You can use calculator in ParaView to do so.
Make use of pressure, density. Get velocity components by dividing momentum with density and use the enthalpy formula..

Thanks for the help! Would you mind detailing the steps? What formula for entropy are you using?

Hi William,

Your first post mentioned Enthalpy so I am assuming that as a variable to be computed.

In ParView, press Calculator and compute a variable with any name you like (let us say Vel_vec) and in formula - Momentum/Density

Again highlight this Calculator1 and compute Total specific enthalpy (Hs or whatever name you like) with (let's say 2D case) formula -
Pressure*3.5/Density+0.5*(Vel_vec_X*Vel_vec_X+Vel_vec_Y*Vel_vec _Y)
(here 3.5 is for gamma/(gamma-1)).

Best
Amit
