Hi Foamers,

after two months without success in getting a LamBremhorst-low-Re-Ke problem (calculate drag coefficient) to work, i hope someone could help me with some experience.

- i have a polymesh made with ccm+.
- no problems are found by checkmesh.
- with inlet velocity 0.1 m/s simpleFoam is running, above k and eps
explode after some iterations..

i read you can play with the inlet bc for k and eps..

could someone post his settings for a steadystate flow with simplefoam and high flow velocities?

attached are my setting files.

All the best,
Moritz
