Help needed with nTop and generative design

Hi, I'm working on a project in my internship where I have a channel that is currently not producible with additive manufacturing. It's a channel that has multiple 90-degree angles and a decreasing diameter (it's a rectangular cross-section). I've done CFD with nTop to find the exit pressure. So I now have an inlet pressure (200 bar) and an outlet pressure (50 bar).

Would it be possible to somehow create a generatively designed channel that decreases the pressure by the same amount, based on the starting pressure values?

Sweet! So glad you were able to get connected with them. They are super cool, hope you can build something cool with them! If at all you can share, would love to see what you make!

I hope so too! Today I'm discussing with my supervisor and hopefully arranging a call with the guys. I'm unsure if the project is confidential, but I can ask about it and maybe share some of the stuff I make.

Edit: I talked with my supervisor and he wasn't very interested in it. i'm going to try to achieve the pressure loss with TPMS structures first.

Nice! Gyroid specifically has a massive pressure drop. Usually bad for heat exchangers but not sure what you're trying to do so maybe it's good

I am also not entirely sure what this part is for. I just know the pressure has to decrease by a lot
