ソルバー | CD-adapco
クラス最高のソルバーと包括的な物理モデルであらゆる流動様式をカバー
STAR-CCM+ は流体において効率的なソルバーを幅広く提供しています。(流体が連続体である限り) 低速から超音波まであらゆる流れをカバーし、単相流から混相流、反応流にも対応します。コア CFD ソルバーは以下のとおりです。
  • STAR-CCM+ is unrivaled in its ability to quickly and efficiently tackle complex geometries. Shown is an analysis with STAR-CCM+ displaying the complex flow patterns as a result of the accidental deployment of a thrust reverser on a business jet while in-flight.
  • In this simulation of an F18 flying at high angle of attack, the flow around the plane is visualized with streamlines, the pressure is represented over the plane using a grayscale colormap, and the wingtip vortices are shown using an iso-surface of Q Criterion.
  • STAR-CCM+ has a Discrete Element Modeling capability which allows for the simulation of individual particles such as dirt and mud. DEM is especially suited for design of bulk materials and process equipment such as mining trucks, making sure they operate as efficiently as possible.
  • CD-adapco has invested heavily to produce the most productive and robust process in the industry for simulating the aerodynamics performance of ground based vehicles. STAR-CCM+ has a wide range of turbulence models including detached eddy simulations (DES) as shown on the cab of a truck.
  • High angle of attack re-entry simulation of the NASA X-34 with adaptive meshing for off-body shock capture: STAR-CCM+ offers a comprehensive range of efficient solvers for flow regimes from low speed up to hypersonic (whilst the fluid remains a continuum). Image courtesy of TLG Aerospace.
  • STAR-CCM+ is unrivaled in its ability to quickly and efficiently tackle complex geometries. Shown here are surface pressures on an Airbus A380 with flaps deployed and landing gear modeled. Streamlines visualize the flow pattern in the wake of the aircraft.

分離型

分離型ソルバーは非圧縮性流れと弱圧縮性流れに最適ですが、超音速領域でも良好なパフォーマンスを示します。

連成型陰解法

連成アルゴリズムは圧縮性流れで特に衝撃が存在する場合に、正確でロバスト性の高い解析が得られ、高レイノルズ数の自然対流に最適なソルバーです。

連成型陽解法

高速、短時間、非定常の圧縮性流れに特に適しています。

STAR-CCM+ には多くのソルバーが搭載されており、特に固体応力向けの有限体積ソルバーは流体-構造連成 (FSI) などの用途に有効です。
