 The self-nesting can be operated as a 1-way nesting, where only the anterpolation step is omitted, i.e. there is no feedback in the parent by the child model, and as a 2-way nesting, where parent and child solution mutually depend on each other. 
 
-Child models can be recursively nested within each other under the condition that the child model fits completely into its respective parent domain without any overlap. 
+Child models can be recursively nested within each other under the condition that the child model fits completely into its respective parent domain without any overlap. Please note also that the parent / child grid spacing ratios in each coordinate direction must be integer valued. This also implies that vertical grid stretching is not allowed in nested runs except in the root domain above the top level of the highest nest-domain.
 
 To apply the self nesting, the namelist [wiki:doc/app/nestpar#nesting_parameters &nesting_parameters] must be provided.
