One method is to integrate FEA result and test data together, which makes a new way for visualizing test data and help to improve test analysis and evaluation. Test data is typically collected in a waveform data type while FEA visualization typically presents results in 3D geometry. In addition, test data collection locations are sparse compared to relatively dense FEA mesh results, this method uses position matching and mapping method to generate node data on basis of test data and FEA results, and plots generated data on FEA model in color cloud picture mode, thus makes it possible for visualizing all remaining nodes which cant be collected by test. Another method is to integrate simulation data and environment data together, which gives engineers more context about the visualizat
