Hi. Is there a way to simulate flow of the fluid if you have some moving object in it such as propeler mixer with some rpm. The fluid would be in a kettle that is not full. Maybe also simulate waving on the fluid surface?
If it's not possible, what other software can do that?
Flow Sim can model the moving object (mixer in this case). But currently, we fall short on being able to do one that is not full, i.e. a free surface problem. But there maybe some way around this, depending first on what the objective of the analysis is exactly; again I repeat this in many post responses, the objective or what you are trying to get out of the model is the first question always to ask. How much "wave action" are you expecting?
As far as software is concerned, do you know about cfd-online.com? Typically this type of analysis requires a program with a higher price point.
