S_InitialStep

Purpose

script for initial step of incremental analysis

Synopsis

This is a script file.

Description

INITIALSTEP script for initial step of incremental analysis
  the script initializes the state of the structural model and sets up the necessary
  variables for the load factor evolution under the given load pattern;
  it starts the post-processing counter pc and saves the initial response state in  Post;
  after this it performs a single load step of static analysis with the parameters in SolStrat

Cross-Reference Information

This function calls:

  • Structure performs requested action on group of elements
  • Increment load incrementation and state advance under static conditions
  • Initialize initialize analysis variables in STATE and load control parameters in SOLSTRAT
  • Initialize_State initialize state variables of structural model and create STATE
  • Iterate equilibrium iterations until convergence under static conditions
  • Update_State final state determination under static conditions, reset increments and history
This function is called by:
  • S_BucklingLoad general script for determining the buckling load of a structural model
