## Description

The input of IC has been prepared for 1D, 2D and 3D models and allows to assign initial conditions to the whole 1/2/3D domain (see Example 1), along predefined surfaces or polylines or by a list of points.

## Parameters

The parameter is defined in subsequent line below the keyword. Example 1 shows an IC file for a model-wide equally distributed constant hydraulic head. The parameter DOMAIN is used to assign values equally over the whole domain. The following geometry types are supported:

• POINT gli_point_name (assigns a specific value (see $DIS_TYPE) to the mesh node which is closest to the point with the name "gli_point_name") • POLYLINE gli_polyline_name (assigns specific values (see$DIS_TYPE) to the mesh nodes which are located along the polyline with the name "gli_polyline_name")
• SURFACE gli_surface_name (assigns specific values (see $DIS_TYPE) to the mesh nodes which are located along on the surface with name "gli_surface_name") (TODO not benchmarked?) • VOLUME gli_volume_name (TODO not supported and not benchmarked?) • DOMAIN (assigns specific values (see$DIS_TYPE) to each mesh node of the whole model domain)
• SUB_DOMAIN (TODO check)
