- Keywords are case INsensitive.
- Comments are indicated by a #.
- The keyword FileVersion (= 1.0) must be the first keyword, the order of the other keywords is free to choose.
- The pressure correction on boundaries using Paver and Pcorr, which used to be prescribed in the wind files, has been moved to the MD-File. The correction is specified using the keyword:
PavBnd (P average on Boundaries). This average pressure is applied on all boundaries to avoid pressure gradients there. The pressure needs to be specified in Pascals.
