Step 1 – Geometry Preparation (Idealization)

Import CAD geometry from NX or other CAD systems.

Use geometry idealization and preparation tools to remove unnecessary details such as small chamfers, fillets, holes, or other features that do not materially affect the simulation but may increase computational complexity.

Step 2 – Define Material Properties

Assign the mechanical, thermal, and physical properties required for the analysis, such as:

• Young’s modulus
• Poisson’s ratio
• Yield strength
• Thermal conductivity
• Coefficient of thermal expansion
• Density

Step 3 – Finite Element Meshing

Create a finite element model using appropriate element types, including:

• 1D elements for beams and rods
• 2D elements for shells and thin-walled structures
• 3D elements such as tetrahedral or hexahedral solids

Mesh density and element size can be adjusted according to geometry complexity and required solution accuracy.

Step 4 – Define Boundary Conditions & Loads

Apply realistic constraints, contacts, and operating loads, including:

• Fixed constraints and supports
• Contact conditions
• Concentrated forces
• Pressure
• Torque
• Angular velocity
• Temperature
• Gravity and acceleration

Step 5 – Solve the Simulation

Execute numerical calculations using Siemens simulation solvers according to the required analysis type.

Simcenter 3D can work with technologies such as Simcenter Nastran, nonlinear solutions including SOL 401/402, and dedicated thermal, flow, and other multidisciplinary solvers.

Step 6 – Results Evaluation & Post-Processing

Visualize simulation results using 3D contour plots, animations, graphs, and engineering reports.

Typical results include:

• Von Mises stress
• Strain
• Displacement
• Temperature distribution
• Natural frequencies
• Mode shapes
• Time- and frequency-domain responses
