Possible Problems & Solution
ENVI-met reports Captured Grids
Captured Grids are single, free grid cells which are totally neighbored by occupied grid cells (see also here).
ENVI-met warns about this, but normally they do not cause problems.
ENVI-met cannot find a good Spacing between the Top of the 3D Model and 2500
Please have a look at Vertical Grid Layout.
