I am getting the below error [image] in this project I want to make a simple multiphase simulation, where I have to chambers with air connected by a pipe with water in it. I assign air to the two top solids and water to the bottom solid. Simscale gives me an error saying I need to assign exactly…

Hi, I just created this simulation starting form your model, so you know how it should be done: SimScale Login Log in to your SimScale account. SimScale makes high-fidelity engineering simulation technically and economically accessible. At any scale. In the cloud. …

Hey there! I just opened the project and found a different error: A multi-region mesh was assigned - this analysis-type requires a single-region mesh. This is because you have three parts in your model. If what you need is to specify the initial presence of the phases, you should use geometry pr…

I would like to carry out a very simple simulation where I have different pressures in the two chambers filled with air. The chambers are connected by another chamber filled with water. I want to see the height of the water change due to the pressures acting on the water surface as seen in the belo…

Hi again, thank you very much for your thorough answer. I still have a of question I hope you could clarify: You assigned the materials air and water to every part of the solid. I guess that makes sense because every part of the solid can potentially contain water or air? When I originally assigned…

You are welcome! Yes, that is right, just bear in mind that in a multiphase simulation, only one part domain is allowed, thus you need to assign both materials to the one part.
