Fsi Foam parallel problem

Hi all,

I started fsiFoam in parallel, but it gaves me the bold error. Serial processing work, but not parallel. Everyone has any idea?

Code:

Create time



Create dynamic mesh for time = 0



Selecting dynamicFvMesh dynamicMotionSolverFvMesh

// using new solver syntax:

motionU

{

    solver          PCG;

    preconditioner  DIC;

    tolerance       1e-06;

    relTol          0;

}



Selecting motion solver: velocityLaplacian

Selecting motion diffusion: quadratic

Selecting motion diffusion: inverseDistance

 Reading stress mesh

Selecting incompressible transport model Newtonian

Selecting turbulence model type RASModel

Selecting RAS turbulence model SpalartAllmaras

SpalartAllmarasCoeffs

{

    sigmaNut        0.66666;

    kappa           0.41;

    Cb1             0.1355;

    Cb2             0.622;

    Cw2             0.3;

    Cw3             2;

    Cv1             7.1;

    Cv2             5;

}

Selecting rheology model linearElastic

Hello,

I'm using also fsiFoam to run a case, however, still no solution for parallel simulation with that. Could you please let me know did you find any solution?

more or less same error:

[2] --> FOAM FATAL ERROR:
[2] Cannot find file "points" in directory "constant/solid/polyMesh"

Thanks

Hi mahdi, I am also facing the same problem...Have you solved it?

you are probably using scotch for decompose algorithm, first try simple algorithm in you decomposeParDict.

cheers
