i want to model a Semi-submersible propeller which is a multiphase problem. my target is to show the advantage of using GPU accelerator in solving complex problem and discover how much GPUs can fastened the process of solving. i am going to use ANSYS Fluent v16.0. Is Fluent capable using GPU like Tesla K80 to meet my requirement? Do i have to write a code or any kine of consideration in order to solve my problem? any advice will be greatly appreciated.
not sure about Fluent, but there is a 2-phase lattice Boltzmann code with GPU, released under OpenSource

Dear Steffen Berg, i appreciate your reply, i checked the link and I realized that it ls a single phase code:
Features
•single phase and binary fluid (Shan-Chen, free energy) flows
•on-line 2D and 3D visualization (interactive in 2D)
•multiple output formats (Numpy arrays, VTK, HDF5, ...)
•support for both CUDA and OpenCL devices
•template-based run-time code generation for optimal simulation performance
•runs on Linux, Mac OS X, and Windows
The problem i am going to model has a complex geometry either. after 2 days of searching i can concluded that it is barely possible to solve such a problem by cfd using GPU (a great software like Fluent can not handle it right now, an opensource code neither).
I found a document from ANSYS which declare that it is impossible to do it! on page 17
hi Bijan
could you find a way to simulate the semi-submereged propeller?
can you help me with this?...
thanks
Hi Amirhossein
it is possible to model with MRF and Dynamic mesh. But MRF does not show the rotation of the propeller. Use dynamic mesh if you are interested to visualize the rotation and i can say it is more accurate.
