OBJECTIVE
Concentrating on a space of several km or less, we are developing an unsteady,
non-linear-type numerical simulator called the RIAM-COMPACT
(Research Institute for Applied Mechanics, Kyushu University, COMputational Prediction of Airflow over Complex Terrain).
The RIAM-COMPACT adopts an LES (Large-Eddy Simulation) technique as a turbulence model.

FEATURE
Calculation time for 1 simulation : 30 minutes (Windows OS PC, 51x51x31mesh)
Possible to calculate annual energy output (see figure below)

Developed and Sold by RIAM-COMPACT Co., Ltd. (Established 2nd Oct 2006)

The relative error to the observation value of an annual average wind speed was within 10%.
