Astronomy, Geoscience and Environment engineering Platform

 

The goal of Astronomy, Geoscience and Environment engineering Platform (AGEP) is providing a high efficient and convenient platform for simulations of the evolution (long and short term) of earth, oceans, atmosphere, cosmos and environmental pollution. We hope the simulation results can improve our knowledge of various environment types and the relationship between environment and human activities, as well as provide the scientific basis for economic activities and policy-making.

AGEP has five sub-platforms, 1) Geology; 2) Astronomy; 3) Oceanology; 4) Cosmology; 5) tool, which are all interrelated. For example, simulations of climatic changes naturally involve seawater evaporation and ocean current, simulations of factory pollution involves air pollution and water pollution. Besides, these sub-platforms are also connected to other application platforms: weather research and forecasting can provide regional wind resource distribution for wind power project; coast research provides tidal energy distribution for the front research of industrial simulation. Currently AGEP has 10 open source softwares, and is categorized into five sub-platforms.

The characteristics of software and technology

1) Geology

From large to small, the simulation scale is divided into earthquake, geological structure, mineralogy and mineral resources. In this field, the most popular method is Finite-Element Method (FEM). Different geological research can be done by using FEM software and different physical parameter. Softwares: CESM, paraFEM, Moose Framework, OpenFoam.

2) Astronomy

From large to small, the simulation scale is divided into global atmosphere, climate, weather, pollutant gas in the city, gas leakage and fire. The popular method is to combine of FEM and Finite Volume Method (FVM). Some software needs real time data.

Softwares: CESM, WRF, CMAQ.

3) Oceanology

From large to small, the simulation scale is divided into global ocean currents, ocean and estuary. The popular method is FVM based on the knowledge of hydrodynamics and unstructured grid. Simulation of ocean is directly connected with many economic industries, such as estuary dredging, harbor construction, tidal energy, treating ocean contamination, fishery resources and the effect of sea ice on climax and air route.

Softwares: CESM, FVCOM, ELCIRC.

4) Cosmology

In cosmology, the largest scale is also the smallest scale. As a result, we categorize the software in terms of function. Research methods involve knowledge relevant to quantized field theory and Statistical Physics. Given the modern physical theory’s incomplete understanding of the cosmology, it is unlikely to have simulation software of widely acknowledgement in a short time. This type mainly contributes to supply an environment easy to compile with and parallel algorithms for optimizing the applications.

Softwares: Cubep3m

5) Tools

Two of the most important steps in AGEP are establishing a model and making a grid on it. As a result of this, we supply some softwares for pre- and post-treatments in AGEP.

Softwares: Salome
