RAMDO V&V was used in conjunction with SCIMITAR3D to predict mushroom diameter and bar length for a Taylor bar impact problem. Input variables for the simulation included: yield stress, strain hardening constant, and strain hardening exponent. The previous approach to validate this simulation performed a point-wise comparison, which ignored the variability of the input variables. RAMDO’s V&V included analyzing input variability and performing a model validation that helped engineers confidently compare simulation data with test data.
RAMDO V&V was used in conjunction with ANSYS topology optimization to analyze an offshore platform panel structure design. The previous approach used only three simulations and three experimental data points to validate the model, leaving engineers with an unknown level of accuracy and confidence in the model’s predictions. When RAMDO’s V&V was applied, engineers were able to produce a statistical comparison between simulation output and test data and provide a confidence-based error level.
