Altair SimSolid 2019.4.0.59  一種快速，準確，穩健的結構模擬仿真技術
SIMSOLID是一種快速，準確，穩健的結構模擬仿真技術，無需進行幾何簡化，清理或網格劃分。AltairEngineering是企業級工程軟件的領先供應商，包括solidThinkingEvolve等等。

SIMSOLID建立於一個簡單的問題：“為什麼設計和結構模擬世界中使用的幾何必須如此不同？”

SIMSOLID是專為設計工程師開發的結構分析軟件。它消除了幾何簡化和網格化，這是傳統FEA中最耗時和專業的兩項任務。

此外，SIMSOLID可以分析與傳統FEA不相關的複雜零件和大型組件，並在台式計算機上高效地完成。SIMSOLID既快速又準確，使用獨特的多通道自適應分析控制解決方案的準確性。
