Dear friends.

i try made jump pressure that like a fan internal field.

I want to give a free flow around the fan and give a certain boost after passing the fan, but I don't know how to do it.

If you know how, please let me know.

thank you, friends.

If you google for openfoam fan tutorial, you find e. g. this one:

It probably does what you want. There is some "magic" for creating the boundary conditions. Especially, have a look at https://github.com/OpenFOAM/OpenFOAM...ateBafflesDict
