COMPOSITE PROCESS SIMULATION: VALIDATE PREDICTIONS AGAINST PARTS
Editable planning/verification record — Yenra
Updated: October 2, 2026
Article: https://yenra.com/composites-manufacturing-process-simulation-software/

Purpose: Define a simulation decision, document material and process inputs, compare predicted defects or deformation with measured parts, and record where the model remains unvalidated.
Intended reader: Composite process engineers and simulation project owners

HOW TO USE
Save a working copy. Enter the actual specification, units, assumptions and evidence references in each field. Preserve original observations and record changes. Have the responsible reviewer resolve missing or conflicting requirements before release. Examples below are fictional teaching inputs, not process settings or acceptance standards.

RECORD
1. Decision to support, process route and permitted model-use range:
   ____________________________________________________________

2. Geometry/tool revisions, ply stack, orientation and material lot:
   ____________________________________________________________

3. Material characterization sources, test conditions and fitted parameters:
   ____________________________________________________________

4. Boundary conditions, contact/friction, thermal history or flow inputs:
   ____________________________________________________________

5. Solver/version, mesh/time-step study, convergence and warning review:
   ____________________________________________________________

6. Outputs, units, sampling locations, acceptance criteria and measurement uncertainty:
   ____________________________________________________________

7. Calibration data IDs and separately reserved validation data IDs:
   ____________________________________________________________

8. Prediction/measurement pairs, residuals and spatial pattern:
   ____________________________________________________________

9. Sensitivity/uncertainty study and limits of supported decisions:
   ____________________________________________________________

10. Changes requiring revalidation and responsible reviewer:
   ____________________________________________________________


WORKED EXAMPLE AND LIMITS
FICTIONAL: At one defined location a model predicts thickness 1.80 mm and a held-out part measurement is 1.70 mm. Signed residual (prediction minus measurement) = +0.10 mm; absolute relative difference using the measurement as denominator = 0.10/1.70 x 100 = 5.88% (rounded). This is one comparison, not overall model accuracy. Consider measurement uncertainty, other locations and pre-agreed decision thresholds.
