COMSOL Multiphysics® Training Course: Nonlinear Structural Materials Modeling (Paid)
If you are a new or experienced user of COMSOL Multiphysics® who wants to learn about performing structural analysis of nonlinear materials, this online training course is for you. Join our 5-day program to explore and deepen your understanding of the Structural Mechanics Module and the Nonlinear Structural Materials Module add-on products.
The course will begin at an introductory level with an understanding of how to build and mesh geometry in COMSOL Multiphysics®. We will then transition to 3D structural modeling using solid elements, which we will follow with an introduction to special elements such as shells, beams, membranes, and trusses. Next, we will delve into nonlinear structural mechanics, covering topics ranging from the sources of nonlinearity to the advanced settings available in the Nonlinear Structural Materials Module. We will also cover some nonlinear material models and conclude with various built-in multiphysics couplings available in the Structural Mechanics Module.
This training course will be held Monday–Friday, August 5–9, with a final Q&A session Monday, August 12.
Schedule
Day 1
Session 1: Introduction to COMSOL Multiphysics®, Geometry, and Meshing
2:30–5 p.m. IST
In this session, we will introduce and demonstrate the capabilities of COMSOL Multiphysics®.
