yes, there are a number of conversion tools from various mesh formats to nek5000. But one needs to keep in mind that the mesh quality is crucial if you want to exploit the benefits of a high order method. Philipp On 2018-07-25 14:25, [email protected] wrote:

Thank you for your clarification,

It seems my assessment was wrong. In my research, adding a roughness is not the main point, but it still should be considered. It doesn't matter which approach I go with as long as it is easy to implement by Nek5000. Anyway, I think I should do more research on these two approaches (NekNek and IBM) or I can build the mesh with a third-party program and convert it to Nek5000, right?

Again, thank you for your assistance,
