Prevent silent accuracy drift in NeqSim simulations by managing regression baselines that capture current results, generate fixture files, and define regression tests for CI validation. This workflow detects regressions when modifying solver logic or EOS implementations.

Regression baseline management for EOS implementations captures current thermodynamic property values into fixture files and defines tolerances. It generates regression tests that CI pipelines validate, ensuring changes to solver logic do not silently degrade multi-component system accuracy.

Create regression tests for NeqSim property correlations by capturing current baseline values for key models, generating fixture files, and adding drift-detection tests before modifying solver logic. CI then validates these tests to prevent unnoticed regressions.

Yes, NeqSim regression testing works with multi-component systems. The drift-detection workflow supports both single- and multi-component systems, capturing baseline fixtures and validating thermodynamic property benchmarks across them when EOS implementations are modified.

Update regression baselines for thermodynamic models when external references validate the change and the new results are confirmed accurate. This ensures the baseline reflects intentional corrections rather than silent accuracy drift from modified property correlations.
