STREAM

構造格子系汎用三次元熱流体解析システム
Horizontal spacer

STREAMは、電子機器、建築土木などさまざまな業界で使われ続け、既に30年以上の実績を誇る汎用の熱流体シミュレーションソフトウェアで、進化し続ける圧倒的な使い易さと高速演算が特長のツールです。

直交構造格子は、解析対象物をさいの目状にメッシュ分割するため、メッシュの作成が手軽に行えます。球体や円柱など丸みを帯びた部分は階段状に表現されます。そのため、細かい形状が結果に影響しない電子機器の放熱シミュレーションや建築分野における室内空調シミュレーションに用いられます。

ソフトウェア機能

Wizard driven analysis conditions provide an easy to learn approach to setting up and performing a CFD simulation.

Using a structured mesh, models can quickly and easily be converted into a computational domain without the needed model preparation that is typical of an unstructured mesh.

scSTREAM uses a structured Cartesian mesh. Structured meshes are composed of many small cuboids, so it is very easy and quick to construct. In applications where attention to tiny details and curved surfaces do not have a strong effect on the simulation a structured mesh becomes very beneficial.

For a Cartesian mesh, each element face normal are aligned with the axis’s, making the calculation faster by reducing the number of calculations needed to determine the flux.

Flow generated from moving objects can be considered during translation, rotation, or elastic deformation of an object. The mesh of the moving object is created separately from the stationary mesh, this makes moving an object large distances computationally inexpensive.



scSTREAM interfaces directly with BIM 2.0 Autodesk® Revit® and GRAPHISOFT ARCHICAD. This allows for direct part targeting and the part tree can be kept and simplified. IFC format can be imported directly.

In addition to architecture there is a tool designed specifically designed to create precise electrical circuit components. After specifying design parameters, Electronic Parts Maker can consider various semiconductor packages such as: QFP, SOP, and BGA. Both Delphi and Two-Resistor modeling are also included.
