How To map pressures from CFD simulation

Hello Everyone,

I want to import a pressure map obtained from a CFD simulation for a aerodynamic component of a Formula Student Car. To do that I saw that I must export the mesh of my model in a  .dat file and import it in the other software (StarCCM+ in this case) so that it associates the pressure for each node of the mesh of my component. I did it, even though I'm not sure on the correctness of this procedure, and I'm trying to import it in Hypermesh but is not working.
I looked for some similar tutorial but I do not find anything helpful enough.

Can anyone suggest me how to do that in the correct way?
Thank you everyone!
