Hi everybody,

I'm doing an atmospheric boundary layer around a flat body near the ground.
I've reached a steady solution and now I want to adapt the mesh to carry on with the iterations.
I've checked several tutorials about adapting the mesh, here's one of them:

http://aerojet.engr.ucdavis.edu/flue.../tg/node21.htm

I've chosen to adapt based on Static Pressure gradient. Method is gradient and for normalization I've tried two options.

First was to select standard normalization and set the coarsen threshold to 0 and the refine threshold to the 10% value of max static pressure, as sugested by the tutorial. I click on mark and no cells were selected for adaption.

Second option was to select Scale normalization and set the coarsen threshold to 0.3 and the refinde threshold 0.7 as sugested by another tutorial. As before, no cell was marked for adaption.

Any body can help me with the adaption setup? What should I do to get some cells marked to adapt?

Any help will be highly appreciated. Thanks in advanced.
