Databases, Indoor

This example contains a collection of several indoor geometry databases and does not require any preprocessing.

Applicability of the Databases

The models are indoor database binary (.idb) files and can be used directly for simulations in ProMan with all prediction models, except the intelligent ray tracing model (IRT) prediction model.
Note: The databases were created in WallMan and can only be modified in WallMan.
In indoor databases, the orientation of objects is arbitrary, and more detail can be included in the database1. Therefore indoor databases are generally limited to smaller areas with fewer buildings. However, the environment can still be arbitrary – ranging from a small campus down to a single room. A simulation outside a building can be based on such an indoor database and is then classified as an indoor scenario.

Name Description

This model is of a campus that contains a multi-story building, surrounded by several other buildings. As the model contains only a small area with only a limited number of objects, it was created in WallMan as an indoor database2.

Individual materials are defined for each wall or object. For example, black boards are colored green; windows are glass blue. View the material properties in the Material Catalogue at Edit > Materials.

Convention Center Small.idb

This model is of a single-story small convention center. Colorized materials are used to distinguish between material properties of the objects in the Material Catalogue.

Industrial Two Floor.idb This model is of a two-story industrial building. View the material properties for exterior walls, interior walls, pillars, and windows in the Material Catalogue.
Office 1.idb This model shows the interior of a rectangular office building that consists of different interior rooms and cubicles. The interior walls of rooms and dividers for cubicle are made up of metallic material. Outer walls are made of concrete material. View the electrical properties of the walls and dividers in the Material Catalogue.
Office 2.idb This model shows the interior of an office building. The thickness of the walls is 10 cm.
Office 3.idb This model shows the interior of a T-shaped office building that contains several small rooms.
Office Multi Floor.idb This model is of a multi-story office building with six stories. Materials are distinguished by different colors. View the material properties in the Material Catalogue.
Research Institute Single Floor.idb This model is of a single-story research institute. The outdoor glass windows are shown in blue, while interior walls of the rooms consist of wood and are colored orange.
SBS_Office.idb This model is of building with a combination of single-story, two-stories, three-stories, and four-stories. The green-colored ceiling (10 cm thick) is visible in the 3D view of the model. The maximum height of the building is 15.08 m. The model contains a ground plane of 20 cm, and its electrical properties are defined in the Material Catalogue.
Small Single Floor.idb This model is of a single-story building. All materials used are displayed by a single color.3
Triangle.idb This model is of a triangular building with different materials for desks, walls, pillars, room separations, glass, and ground.
University.idb This model is of a square building. A default material is used to create the building, which includes a large number of rooms. The maximum height of the building is 10 m.
Vienna.idb This model is of a single-story building with a height of 5 m. Different colors represent different materials.
VirginiaTech.idb This model is of a single-story building that contains a combination of exterior walls, interior walls, special walls, and doors with different electrical properties.

With WallMan, you can define 3D regions with furniture or with people present with no requirement to define precise shapes and locations. These regions do not reflect or diffract propagation rays, but they add additional attenuation to the computation.

1 Urban databases differ from indoor databases whereby all objects are polygonal cylinders.
2 An indoor database offers the geometrical freedom needed to describe all structures.
