FLUENT or CFX

huda123 · October 27, 2014, 03:34

Hi,

I am currently working on a project to study the effect of hydrodynamic forces acting on slings of an object being lifted down onto the seafloor through the splashzone.

May I have suggestions as to whether FLUENT or CFX is the better method for the solver part? I do not have access to ASAS(I wish i had).

Is it better to model the entire system (object, crane vessel, slings, wave tank) in another CAD software I am more familiar with, then import it over to workbench, or is it more appropriate the model the system within ANSYS itself?
Thanks.

Hi Aminul,
I do not have much experience with CFX, but people say that it is better for 3D problems. So if you are modelling a 3D problem, go with it. Otherwise, Fluent is good to use.
In regard to your other question, i is better to create your geometry with ANSYS design modeler. If you are just working on single design( no modifications needed), then you might be able to import the design from other software and work on it. But if you want to change small parameters and re run the simulations, then its way better to do it in design modeler as you don't have to worry about meshing from scratch every time you make a change. Plus, i always find myself into issues when i try to import geometries from any other software into ANSYS.
