With the improvement of numerical simulation's precision and temperature test's measure methods

better test visualization technique is required.This system integrates numerical simulation and test together

to for visualiz test data

which is a new way for improving test analysis and evaluation.Test data is typically collected in a waveform data type while simulation typically presents results in 3D geometry.In addition

test data locations are sparse compared to relatively dense FEA mesh results.This system 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 can't be collected by test. In the system

specific data structure and interactive method such as cutting

probing and comparison are designed.The construction method of this visualization system can also be applied in statics test and acentric test.
