NetSim uses 'buildings' to differentiate between indoor and outdoor propagation per 38.900 sec 7.4. This means that parameters such as indoor distance and penetration losses are factored into the calculations. However indoor layouts, obstacles, etc would not be available. The O2I Models such as Low Loss and High Loss are associated with the type of material used in the buildings and are used to calculate the penetration loss in case of an indoor scenario.
If the UE is not within a building it always experiences outdoor propagation loss.
A building by itself does not contribute to multi-path propagation in NetSim. This needs to be configured. Multipath shadow fading can be introduced by setting channel characteristics to PATHLOSS_SHADOWFADING or PATHLOSS_SHADOWFADING_O2ILOSS instead of LTENR_CHANNELCHAR_PATHLOSS_ONLY.
