True-QSE creates Quasi-Static Events by attaching user defined scaling functions to FEA solutions. True-QSE leverages the power of linear superposition. Like True-LDE, True-QSE supports interaction with the FEA model to create plots of nodal and elemental functions. True-QSE can create operating deflection shapes. 

True-QSE performs linear superposition of FEA results via scaling functions to create:

  • Nodal Functions

  • Elemental Functions

  • Full Field Results


Most structures behave linearly during their operational service events. The loading is usually a complex combination of individual loading events.  True-QSE allows the analyst to understand the time varying nature of the responses to known loading histories.  This is the analytical equivalent of a multi-DOF laboratory test. True-QSE has tools to rapidly plot nodal and elemental functions and the ability to create full field results in a new FEA database. No additional decompositions of the stiffness matrix is required.  Only an existing FEA database with unit load results and defined amplitude functions for input are required to generate complex results. Utilities to generate standard function types like Sine Sweep, Random, Square Wave and Saw Wave are supplied.
