The "Preserve Baseline" allows the 1D boundary of the footprint to be used to prescribe boundary conditions to solvers run on this footprint (e.g. the [[solvers:glads|GlaDs hydrology model]]). If the footprint has n boundary labels, the side wall boundaries after extrusion will be labeled from n+1 to 2n and the lower and upper surfaces after extrusion will be boundary conditions 2n+1 and 2n+2. | The "Preserve Baseline" allows the 1D boundary of the footprint to be used to prescribe boundary conditions to solvers run on this footprint (e.g. the [[solvers:glads|GlaDs hydrology model]]).

| Note that if edge boundaries at the edge of the footprint are grouped together in the .sif, the same groupings must be applied to the wall boundaries directly above them. |

Elmer stores information about edges in addition to element information. This information is not preserved by default through mesh extrusion. To ensure its preservation (this is strictly required if running [[solvers:glads|GlaDs]]) use the "Preserve Edges" option. | Elmer stores information about edges in addition to element information.
