StaticAnalysis

Background

The StaticAnalysis keyword creates an analysis class that computes \(U\) satisfying:

\[ {\textrm F}(U) = R \]

Pre-Analysis

The python Pre-Analysis in the 01-Pre_Process/Method/Attach.py file provides with an interface to create a StaticAnalysis. We use the addAnalysis() as follows:

• addAnalysis(tag, attributes):
  • tag : The identifier of this analysis, i.e., tag > -1
  • attributes : Specific properties for the created analysis, for example
    • 'name' : The analysis's name
    • 'nt' : The integrator's time step

Example

A STATIC ANALYSIS can be defined using the python interface as follows:
SVL.addAnalysis(tag=1, attributes={'name': 'Static', 'nt': 1})

Application Please refer to any python file located at 03-Validations/01-Debugging/ that starts with ST abbreviation.

On the contrary, the 01-Pre_Process/Method/Remove.py file provides with an interface to depopulate the Entities dictionary. For example, to remove an already define Analysis, use:

• delAnalysis(tag):
  • tag : The identifier of the analysis to be removed, i.e., tag > -1

Pre-Analysis

The C++ Run-Analysis in the 02-Run_Process/08-Analysis/01-Static/StaticAnalysis.cpp file provides the class implementation. A StaticAnalysis is created using the built-in json parse-structure provided in the Driver.hpp and is defined inside the "Simulations" json field indicating its "Tag" as follows,

• {
      "Simulations": {
          "Tag": {
              "combo": int,
              "attributes": {
                  "analysis": {
                      "name": "STATIC",
                      "nt": int
                  }
              }
          }
      }
  }
  

  Variable	Description
  combo	The LoadCombo identifier to which the Analysis will be performed.
  nt	The number of incremental step to be performed. By default nt=1.
