AUSTAL View is a graphical user interface for the official German Federal Environmental Agency air dispersion model, AUSTAL2000. 

Ventsim was originally introduced to mining operations in 1994 to help visually design, improve and optimize underground ventilation systems. It is now licensed to over 1000 mine sites, consultants, universities, governments and research agencies around the world. The new Ventsim Visual ventilation software was released in 2009 and offers a graphically rich and dynamic ventilation environment with many more features than the original Ventsim Classic. Ventsim Visual is available in three versions: Standard, Advanced and Premium.

Difference.

Ventsim Visual Standard is a lower cost version based on incompressible flow simulation routines and includes dynamic animated 3D graphics showing real airway dimensions and shapes together with animated air flows. Colours show over 30 different data types including airflow, velocities, various pressures and costs. In addition, the Standard version comes with contaminant spread routines to help predict steady state flow of gases, dust, fumes and smoke.

Ventsim Visual Advanced uses advanced compressible flow modelling, including automatic density and fan curve adjustment, automatic natural ventilation simulation and prediction of temperatures and humidity due to rock strata, auto compression, diesel equipment and electric motors.

Ventsim Visual Premium includes all features of Ventsim Visual Advanced as well as VentFIRE fire simulation, VentLog ventilation survey record software, and the optional LiveView remote data connection and display module.

ARTM View is a graphical user interface for the German Federal Office for Radiation (BfS) ARTM model. The ARTM model calculates the dispersion and deposition of released airborne radioactive materials in the atmosphere. ARTM View is the new standard for the dispersion and deposition calculation of airborne radioactive materials according to the German Nuclear Act. The ARTM model is based on the "TA Luft" and the "AUSTAL2000 model". AUSTAL2000 is a Lagrangian particle tracking air dispersion model from the German Federal Environmental Agency (UAB) (see AUSTAL View). Dose calculations were not included in the ARTM model.
