Simcenter Amesim

1D system simulation across mechanical, fluid, thermal and control

Validate concepts at system level — energy use, control strategy and dynamic response — before the design freezes.

Overview

Simcenter Amesim is a 1D multiphysics platform for systems engineering. It is not about detailed stress in a single part; it answers system questions: is this hydraulic circuit fast enough, what is the energy cost of this control strategy, will the thermal loop hold peak temperatures?

Amesim ships libraries across mechanical, hydraulic, pneumatic, thermal, electrical and control domains, assembled by drag-and-drop. Typical uses include vehicle energy management, hydraulic dynamics, thermal circuit design, control validation and NVH transfer-path analysis.
