Simulation — CAE

Simcenter 3D

Structures, acoustics, flow, thermal and motion in one environment

Simcenter 3D unifies multiple physics in a single platform with associative geometry — change the design and the model updates instead of being rebuilt.

Overview

Simcenter 3D is the Siemens 3D CAE platform covering structural strength, durability, acoustics, fluids, thermal, electromagnetics and multibody dynamics. It integrates deeply with NX: the simulation model stays associative with the CAD geometry, so design changes drive mesh and boundary-condition updates directly — the step that costs the most time in traditional, disconnected CAD/CAE workflows.

The platform ships with proven solvers such as NX Nastran and can also post-process third-party results. For coupled problems — fluid-structure interaction, thermal stress, vibro-acoustics — Simcenter 3D provides a unified data-transfer mechanism that removes the errors of manual mapping.

Key capabilities

Associative modelling

Stays linked to CAD; incremental updates after design changes instead of rebuilds.

Multiphysics in one place

Structures, thermal, flow, acoustics, motion and composites solved in a shared environment.

NX Nastran solver

Long-industry-validated solver for linear, non-linear and dynamic analysis.

Composites

Ply definition, failure criteria and interlaminar stress for lightweight design.

Vibration & acoustics

Modal, frequency response, random vibration and acoustic analysis for NVH troubleshooting.

Process automation

Template and batch-run simulation workflows, turning repetitive analysis into reusable assets.

What it delivers
