Hi everyone! I'm tring to simulate the flowfield on a stationary VAWT for some debugging. In the complete simulation (VAWT rotating) iterations start, but do not make sense. So I'm trying the same dictionaries with no rotations. Using pimpleFoam unstead of pimpleDyMFoam.

After running the first iteration for U, this appears:

Code:
#0  Foam::error::printStack(Foam::Ostream&) at ??:?
#1  Foam::sigFpe::sigHandler(int) at ??:?
#2   in "/lib64/libc.so.6"
#3  double Foam::sumProd<double>(Foam::UList<double> const&, Foam::UList<double> const&) at ??:?
#4  Foam::PCG::solve(Foam::Field<double>&, Foam::Field<double> const&, unsigned char) const at ??:?
#5  Foam::GAMGSolver::solveCoarsestLevel(Foam::Field<double>&, Foam::Field<double> const&) const at ??:?
#6  Foam::GAMGSolver::Vcycle(Foam::PtrList<Foam::lduMatrix::smoother> const&, Foam::Field<double>&, Foam::Field<double> const&, Foam::Field<double>&, Foam::Field<double>&, Foam::Field<double>&, Foam::Field<double>&, Foam::Field<double>&, Foam::PtrList<Foam::Field<double> >&, Foam::PtrList<Foam::Field<double> >&, unsigned char) const at ??:?
#7  Foam::GAMGSolver::solve(Foam::Field<double>&, Foam::Field<double> const&, unsigned char) const at ??:?
#8  Foam::fvMatrix<double>::solveSegregated(Foam::dictionary const&) at ??:?
#9  Foam::fvMatrix<double>::solve(Foam::dictionary const&) at ??:?
#10  
 at ??:?
#11  __libc_start_main in "/lib64/libc.so.6"
#12

Floating point exception
How can I fix it?

RodriguezFatz will become famous soon enough
We need more information.
1) How does the rest of the log file look like?
2) Boundary conditions
3) fvSchemes
4) fvSolution
Cheers,
Philipp.

Michele, you use a wrong syntax for the relaxation factors in your fvSolution file.
Firstly, "p" must be written under "fields" instead of "equations" as far as I know. Thus, I guess your pressure field is not under-relaxated at all.
Secondly, using the ".*" notation relaxes all iterations, also the last one, as someone stated to one of my posts here:
http://www.cfd-online.com/Forums/ope...tml#post481037
So you should not use the ".*".
I will write some more things if you have posted the rest of the log file.

Great, didn't see it.
The pressure solver doesn't work. Could you try to run it with some other setting? If the error remains we need to search somewhere else...
Code:
    "(p|pFinal)"
     {
        solver           GAMG;
        tolerance        1e-12;
        relTol           0.1;

        maxIter         20;    

        smoother         DIC;
    
        nPreSweeps       1;
        nPostSweeps      1;
        nFinestSweeps    2;

        cacheAgglomeration true;

        nCellsInCoarsestLevel 1000;
        agglomerator     faceAreaPair;
        mergeLevels      1;
     }

I've replaced the code you pasted in the precedent post with the precedent one. And changed all the settings in relaxation factors. My fvSolution file now looks like:

Yes. You need to delete the two old entries "p{ ... }" and "pFinal{ ... }" directly below the new one. Otherwise "my" code is overwritten by your old entries and the solver keyword is missing.

Looks like it's the velocity solver this time, right?
I am not a solver expert, so I can't tell you why the smooth solver creates these problems. Usually, I use this setting:


Code:
solvers
{
        "(p|pFinal)"
     {
        solver           GAMG;
        tolerance        1e-12;
        relTol           0.1;

        maxIter         20;    

        smoother         DIC;
    
        nPreSweeps       1;
        nPostSweeps      1;
        nFinestSweeps    2;

        cacheAgglomeration true;

        nCellsInCoarsestLevel 1000;
        agglomerator     faceAreaPair;
        mergeLevels      1;
     }
    
    
    
    "(U|k|epsilon|omega|UFinal|kFinal|epsilonFinal|omegaFinal)"    
    {
        solver           PBiCG;
        preconditioner   DILU;
        tolerance        1e-12;
        relTol           1.0e-2;
        maxIter         100;
        };

}

I would recommend a different residualControl setting. I usually use the relTol rather than the tolerance, because you don't have to concern yourself with the absolute values of the residuals. But maybe others think differently about that !?
Then, I would also lower the nOuterCorrectors to something like 20. If you can't get residuals down in 20 iterations, 100 won't work, too.

Well, now it keeps going on.

First time step converged in 12 iterations. But numbers don't match with physics.

Second time step starts with a max Courant number of 76, further more time step continuity errors keep growing.

Code:
 
forces forces output:
    sum of forces:
        pressure : (3.20219e+13 6.22034e+11 -4.0116e+11)
        viscous  : (226981 3372.33 7927.69)
        porous   : (0 0 0)
    sum of moments:
        pressure : (-1.15048e+14 4.54921e+13 -3.75908e+14)
        viscous  : (-1.4342e+06 -2.72523e+06 -1.60083e+07)

lpz_michele is on a distinguished road
this one, as you suggested, right?

Code:
 "(U|k|epsilon|omega|UFinal|kFinal|epsilonFinal|omegaFinal)"    
    {
        solver           PBiCG;
        preconditioner   DILU;
        tolerance        1e-12;
        relTol           1.0e-2;
        maxIter         100;
        };

RodriguezFatz will become famous soon enough
No, I mean the log file is missing the information about the turbulence.

As far as I remember, all the log files I've seen did not write nothing about k-omega. Did I forgot to write something?


Anyway, I tried with the following fvSolution

Firstly, this is not the reason for your problems but: In my view the relTol of 1e-5 is insane. You see it in the later iterations that the linear solvers take 10 or even 65 iterations to converge. Also pressure takes all 20 iterations. In some ordinary simulations all solvers should take something like less than 5 iterations, often just 1 or two. And the outer algorithm still remains stable. There is no increase in overall accuracy by setting relTol to such a low value.

Now, to the actual problem. PIMPLE doesn't converge. You can see the residuals increasing after some initial decrease. You can try to use more stable numerics in the fvSchemes file. Use (1st order) upwind also for the velocity and uncorrected scheme for laplacian instead of corrected. Did you try to initialize the flow field with potentialFoam?
