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;
}

Thanks.
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

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


cheers
