However, the default settings of ANSYS' nonlinear solution control parameters must be changed to allow Helius PFA to improve the convergence characteristics of the simulation.

Helius PFA's method of managing material nonlinearity is specifically designed to handle this localized non-smooth material response. This non-smooth material response is one of the primary factors responsible for the difficulty in obtaining convergence in progressive failure simulations. However, in a progressive failure simulation, the nonlinear response of the composite structure is not smooth, especially at the local level where material failure results in an instantaneous reduction of material moduli. This document covers only very minimal aspects of APDL. Disclaimer: The ANSYS Parametric Design Language (APDL) is an extensive programming language developed over more than 40 years. My question is how do I apply the load for a certain number of timesteps e.g from 0s - 1.5s through apdl commands. I am wanting to run a transient thermal analysis by applying BFE commands as internal heat generation.

In ANSYS, the nonlinear solution process is based on the fundamental assumption of the Newton-Raphson algorithm that the nonlinear response of the composite structure is sufficiently smooth at both the global and local levels. Objective Provide ANSYS Mechanical users with a briefintroduction to the use of Solution Command Objects for post-processing. Apply apdl command at certain timestep Hi all, i'm relatively new to apdl commands. The image below shows how to type this command into the command prompt. The NROPT command can only be specified via the ANSYS command prompt. The NROPT command is used to do two things: a) instruct ANSYS to use the 'Full' Newton Raphson algorithm, and b) prevent ANSYS from using their 'Adaptive Descent' algorithm to help the solution process.
