Hardware Requirement For Francis Turbine Simulation
I want to carry out simulation of complete Francis turbine and i have gone through tutorial i found i may have about 7o million cells to do fair simulation of Francis turbine.
I have planned to go for parallel computation and i will be using Blade type rack mounted server and i will be carry out complete simulation using either ANSYS CFX or ANSYS FLUENT with URANS-LES.
Kindly suggest optimum hardware i.e.
(1) Processor type and clock speed, core, thread.
(2) Processing time to get solution closure to 10E-5 residual
(2) Required Memory
(4)Time required to simulate 1 million cell
(5) Number of Processors
(6) Optimum Speedup time
(7) Is there a thumb rule for number of cell to Processor and RAM?
Hardware Procurement and finance is not a big issue.
Please help me out as soon as possible.
Thanks in Advance
Here is a presentation discussing a Francis Turbine Simulation:
they used 8 Intel Q6600 Quad cores with 2 Gb each, Processor speed 2.4 GHz.
In the Presentation of the Francis Turbine, they were using from 3.8 to 6.0 million elements. Nothing near 70 million elements. But it still took 8 entry level quad cores to do 3.8-6 million.
Thank you for pdf but it seems very long calculation process...and i think they have considered k-e model and it doesent make reliable results for accurate validation and even they must have taken more than 15 day to get numerical result...so it is time consuming...
I hope you have configured out the hardware issue. Now i'm having the same problem. Can you provide me a hardware to configure a good resolution cfd analysis of a francis turbine.
And the other question is are you using transient simulation of a method like MRF ?
With my best wishes....
You go through Ansys CFX Manual, it has suggested some guide line of minimum required Hardware i.e. CPU power + RAM with respect to flow modeling type and equation sets to carry out CFD simulation. If you will not get this, ask specific questions i will response.
