    Hi baris,

    what does nsweeps represent in the solver. The motorbike case has nsweeps assigned as 1, I was not able to get clear explanantion in the internet.

     

    ex:

    k
    {
    solver smoothSolver;
    smoother GaussSeidel;
    tolerance 1e-8;
    relTol 0.1;
    nSweeps 1;

    Hi Konka,

    this is number of solver iterations between checks for solver convergence before the calculation of residuals. Simply, it shows number of iterations when smooth solvers are used. You can increase if you wanna make more iterations to reach your decided tolerance before the residuals are calculated.

    As I said When using the smooth solvers, the user can optionally specify the number of sweeps, by the nSweeps keyword, before the residual is recalculated. Without setting it, it reverts to a default value of 1.

    For your info.

    Best.
