Hi! I'm would like to ask if there's any open source available for FE/Fluid analysis?

I'm planning to use it to simulate icing and melting process in a ice storage based on different geometry.Its something like a fridge with coolant ect. I would like to simulate the icing and melting process with the consideration on the different shape(where the icing occur) and in consideration of its coolant and energy needed. For the geometry/shape i would be able to use CREO student version to work with.
