Simcenter Nastran—a powerful FEA tool
Analyze structural strength, vibrations and acoustics
with precise and scalable simulations
Predict responses to real-world forces
-
01
Prepare modeling
In the preprocessing phase, geometry is defined, which can be imported from CAD software. The model is discretized into finite elements and divided into smaller, simpler parts that are connected at nodes. Material properties and boundary conditions are assigned, which describe how the model is supported and loads that it may experience.
-
02
Specify analysis types
Specify the type of analysis to conduct, such as static, dynamic, thermal or aeroelastic. Each analysis type requires different settings and inputs. Simcenter Nastran provides the tools to set up these analyses effectively, including defining how the simulation interacts with physical phenomena and what results are of interest.
-
03
Solve equations
Simcenter Nastran uses numerical methods to solve equations that describe the behavior of elements under given loads and constraints. Complex computations predict displacements, stresses, strains, vibrations and other physical responses. The solver handles calculations efficiently—even for large and complex models.
-
04
Assess design performance and safety
After calculations are complete, results are typically output in forms that require interpretation. This phase is handled through post-processing software, which may or may not be integrated into Simcenter Nastran. In post-processing, results are visualized and analysts examine results to assess the performance and safety of designs.
-
05
Optimize and iterate
Simcenter Nastran supports this iterative process by allowing for adjustments and re-analysis to refine a model and its performance according to the desired specifications, identifying issues or areas for improvement.
