Hello, I am new to Simscale and I am working on a capstone project on hydropower plants. I want to simulate the flow of water through a turbine similar to those found on the La Rance power plant. I want to use the results of the simulation to improve the design of the turbine as well as the pipe gu…

Hi @fkaepn ! I will forward this parasolid meshing issue to our engineers and let you know how you can keep working on your project. Have you tried another format in the meantime? Keeping you up-to-date! Jousef

@fkaepn : please follow the guide about Internal CFD simulation with MRF zone: https://www.simscale.com/projects/Retsam/karlomrftest/ . Your geometry should be modified. Cheers, Retsam

Hello Retsam and thank you for your help. I read the guide you published and I would like to ask you for some clarification concerning the blades. If I understood correctly, the blades are cylindrical holes in the cylinder that represents the pipe, is that right? Are they like hollow cylinders in …

Hi @fkaepn [image] fkaepn: Are they like hollow cylinders in the pipe cylinder? Yes, that’s it. I made them as flat cylinders to limit number of faces (top, bottom and side). Cheers, Retsam
