Hi Foamers,
I have a Problem in building and using the metisDecomp libary. I get this error when I want to use the metis decompose method: Quote:

Thanks for your help.

Metis is not part of the ThirdParty package in 2.0.x. You might want to try the scotch decomposition library, which essentially offers identical functionality.
Best,

Scotch might provide similar functionality, but a head-to-head test of metis vs. scotch shows that for the same mesh (in my case a large, 20M cell mesh), metis decomposes a mesh approximately twice as fast as scotch.

I had the same problem, where can I find Metis? Is it free?

Hello everybody,
I've just spotted this post by searching the forum for metis. I managed to compile and run metis decomposition. I posted some details here http://www.cfd-online.com/Forums/ope...m-2-1-0-a.html If you need help I can supply the necessary files and maybe some advice. |

Just a little curiosity, do you see significant advantages with metis in comparison to scotch?

I've just run scotch and metis on damBreakFine case. The execution time was on 14s on four processors with scotch being slightly (13.55s) faster. When I run some bigger cases I will do more testing and I will let you know.

Thanks: I have never actually compared, but it would be interesting :-)

Alberto,
I haven't yet run the bigger comparisons as I promised. I am retained in a bit different pursuit, but I'll do that as soon as I'm done with my current project. I have however been playing with scotch, metis and twoPhaseEulerFoam. I am doing a 2D channel and scotch crashes on a case with 262144 cells. Metis seems to run ok on the same case. This is the first time I am trying a bigger mesh with twoPhaseEulerFoam. For smaller cases scotch was working fine. Here's the error if you're interested. Code:
DILUPBiCG: Solving for alpha, Initial residual = 1, Final residual = 1.07693e-12, No Iterations 3 Dispersed phase volume fraction = 0.5 Min(alpha) = 0.5 Max(alpha) = 0.5 [1] #0 [2]
