This tutorial allows you to complete signal analysis and signal metamodels with Statistics on Structures.
This tutorial demonstrates how to do the following:
Use the results of a sensitivity analysis of a wedge splitting test with signal-type (xy-data) responses
Create a signal Metamodel of Optimal Prognosis (MOP) node
Perform calibration based on the MOP solver
This tutorial requires optiSLang 3D Post-Processing (oSP3D) version 2021 R1 or later and a valid oSP3D; license.
Before you start the tutorial, download the signal_mop zip file from here , and extract it to your working directory.
To set up and run the tutorial, perform the following steps:
Start optiSLang.
Create a new empty project.
