Reply To: Problem on Simulation on increasing the Reynolds Number more than 100.
Dear atanuchaudhury,
thank you for posting.
To increase the Reynolds number and still get stable results, please consider the standard literature on LBM, e.g. the book by Krüger et al. (https://doi.org/10.1007/978-3-319-44649-3).
Basic techniques for this are choosing suitable discretization parameters with experimental stability bounds or using turbulence models as well as advanced collision operators.
We cannot offer full support on debugging your complete application.
You might want to consider taking part in our upcoming spring school for this.
