Size of fluent simulation?

jessicabp · September 2, 2015, 15:35

Hi guys. I was using OpenFOAM for my simulations but I have started to get familiar with Ansys. I am trying to simulate a 3D platform (100m x 100m x 66m) and analyse the wave impact on the pillars. Also, my mesh will be 0.2m. My question is: Do you know the average size of a 3D simulation like this on Fluent? I am worried that my computer memory will not be enough, so I would like to have an idea to find a solution in case I will need to. Thanks!

It's roughly 1 GB per 1 million cells for the mesh alone. Plus storage space for the variables.
