Exercise validation study
validation data, not blanket passes.
Recorded production-solver comparisons against published equations and source-matched public calculations.
Complete manuals · download a whole collection
Each collection includes an editable Word manual and its matching searchable PDF, with linked contents, explanatory text, diagrams and references. Theory equations use native Word mathematics. Individual-page PDF buttons remain available.
These are dated reading editions of the public learning content. Interactive studies and account-controlled classroom notes and databases stay online. For current changes, follow the chapter links back to the website.
Current Workbench, reference editions and downloads
Use the online User Guide for current controls, the released model directory for selectable models and compatibility, and the Training Manual for connected exercises. Wider theory references do not mean every formulation is enabled in Workbench.
Dated GUI captures and compiled Web r18 PDF manuals retain their stated scope; they are not a substitute for current hosted Workbench instructions. Find the overview PDF, guides and exercise databases in Your CDS library.
Study 2026-09-20
138 of 138 exercise baselines executed. 42 passed scoped analytical comparisons; 0 have benchmark discrepancies; 96 have no completed quantitative benchmark; 0 failed execution.
No exercise has experimental validation from this study. A successful run, supplier property or similar-looking plot is not validation. Badges apply only to the listed outputs, recorded inputs and solver revision. Edited inputs and new solver revisions require revalidation.
Case combination regression checks
On 18 September 2026, 52,416 discrete catalog case-selector combinations, including None, were checked against selection compatibility rules: 406 were accepted and 52,010 rejected. These are selection checks, not numerical solutions of every combination. All seven nonempty thermal, moisture and mechanical subsets of the T700 starter executed successfully. Geometry dependency, model-pairing and stale-result checks also passed. This does not validate every material, geometry, load magnitude or coupled physical response.
Method and acceptance
Production solver executed on immutable copies of every exercise. Independent published-equation references use exact baseline inputs where eligible. Scoped analytical badges are not experimental validation, strength approval or validation of edited inputs. Full coupled studies remain unvalidated until matched external evidence and convergence studies exist. Tolerances were declared before numerical comparisons: analytical constants 0.01% + 0.00002 units; beam/strain 0.05% + absolute allowance; rounded NASA table values 1% + 0.00002.
Each validation data panel states its quantities, predeclared tolerances and sources. Independent laminate references use strain/stress coordinate transformations and thickness integration, not production stiffness helpers. Separate NASA fixtures use the report's numerical inputs; they do not confer validation on the unmatched exercise starter.
Findings and outstanding work
- The recorded thin-wall pressure cases pass scoped equilibrium and orthotropic biaxial strain comparisons, including Poisson coupling. This is not a blanket validation of every pressure-vessel exercise or of unverified micromechanics inputs; use each validation data panel for its tested scope.
- The NASA tube fixture matches three published calculated stiffness properties within 1%. This is not an experimental strength or failure validation.
- NASA MAC/GMC micro-property comparisons do not all match the CDS ROM/Halpin–Tsai models. Different model formulations and their discrepancies are retained, not hidden.
- Coupled cure, UV, pultrusion, moisture, sandwich/bonding and progressive delamination require matched constitutive data, boundary conditions, field measurements and convergence studies before a full coupled validation claim.
