Simcenter Nastran Verification Cases
Provider：Siemens Digital Industries Software
Simcenter Nastran ships 800+ .dat verification cases, each with model data and bench values, usable for solver self-checks and version regression.
At a glance
- Readiness
- L3 · Behavior ready
- Rationale
- Engineering L3: each case documents model dimensions, units, section and material data, meshing requirements, boundary conditions, solution sequences and bench values (SOL101/SOL401/SOL402), giving behavior-level reference answers you can check a solver against.
- Scale
- More than 800 .dat verification cases under scnas/nast/docs/verification in the installation, plus companion demo input files in the demo directory (A Siemens support engineer confirmed in a community thread that the Simcenter Nastran v2406 verification folder holds more than 800 .dat files; the manual PDF lists a bench value per case.

- License
- Proprietary but free — The verification manual and cases ship with a licensed Simcenter Nastran installation for validation and learning; running the software commercially requires a valid license, and the cases are not distributed separately.

Why it is listed
The Simcenter Nastran verification set is one of the densest solver-accuracy references in commercial structural analysis: more than eight hundred cases, each specified precisely enough to rebuild the model and compare a computed number against a documented bench value.
Readiness assessment
Every case states dimensions, units, section and material data, meshing requirements, boundary conditions, the solution sequence (linear static, modal, nonlinear, thermal) and the reference bench value, so it functions as an L3 behavioral reference rather than a loose tutorial.
Practical notes
Access is gated: the .dat files live under the installation tree in scnas/nast/docs/verification and require a licensed installation. Because the case list changes between releases, treat the folder in your own installation as the authoritative inventory.
