CFD Tool

  1. Sep 20, 2012 #1
    Hi Guys,

    I have an query. I would like to know the best tool for Simulation, Geomtry and Mesh creation. I want to simulate a duct with a turbine in it as a Part of my research project. I am beginner for the simualtion field so please suggest accordingly the appropriate software. Also please suggest the system specification to run the same tool.

    Is this an undergrad research project? CFD is an extensive field and each of the pieces that you mentioned; geometry creation, mesh generation, and simulation take years of experience before being able to create something so complex as a turbine. As a beginner, I would suggest that you start with something far more simple, like the well studied lid-driven cavity flow.

    There are many different software packages available, but you'll need to see what your University offers. Ansys produces fairly intuitive CFD software.

    Thanks for your reply Smed, Its a post Graduation project. Nothing is available in the institute, Only I have to arrange the software at my own. That why I ask for the most suitable software. About Ansys I have heard that interaction of fluid with turbine is quite difficult.

    Pointwise is the best mesh generator by far. CFD++ seems to give the best results for most things. ANSYS is a decent beginner grade software, but you might need CFD++ for turbine stuff. You'll probably also need to be running it on a super computer. The mesh you'll require for decent results might need in the area of 64 cpus. If you go this route though, you'll have to learn linux as well.

    Hm... I wouldn't call a software package that is certified compliant with design standards in the nuclear industry "beginner grade", but YMMV.

    I'm not saying it's bad, it is a hell of a lot easier to use than the other programs that seem to give better resuls, and by better results I mean closer to experimental. In my experience, much closer. It's a damm good program, just the best to use for people starting out. You wouldn't want to start out with CFD++ on a supercomputer having to use a command shell. That'd scare you off forever.

    I started off with ACE/FASTRAN, which had it's own mesh generation and computational environments. Very good to learn with, but a terrible terrible program in terms of results.

    Note, I did scramjet combustion engine research, not a lot of programs are good at simulating turbulent hypersonic conditions. I'm just refering to ease of use.

    ANSYS Fluent is a great code. It is also a general code, so it is good at a lot of things but not necessarily great any most of them. There are a lot of areas where other solvers are better. I know, for example, that a lot of academe uses GASP for high-speed aerodynamics problems.

    Either way, the more pervasive problem is that the OP is wanting to fund this himself, which is going to be exorbitantly expensive.
