Good afternoon.

I'm starting to use NX10 Flow, and I'm disappointed with the info provided by Siemens. I can't also find tutorials or any material.


I'm trying to simulate a pipe with gravity effect, and I'm having some problems to check the hydrostatic pressure at my problem. First, I can activate buoyancy or not, and second I have boussinesq aproximation or Full Hydrostatic Pressure model.

My results varies if I check or uncheck buoyancy, or I select one model or the other. Since I'm not taking into account heat or temperature, the boussinesq model should be discarded, but I'm still not sure why if I uncheck the buoyancy, the full hydrostatic pressure model, gravity is not taken into account.

I know there is a reference bulk temperature, which I have set to 0, but I'm not sure how do this models work.

Any advice is welcome!
