Nonlinear Course Overview

DRD’s ANSYS Mechanical Nonlinear Structural Simulation

The objective of this course is for our course attendees to develop significant expertise in the use of ANSYS Mechanical for structural nonlinear analysis over a wide range of applications.

The course includes 17 workshops in which the students use topics covered in the course to solve real-world problems. All of the workshops are based on actual problems that DRD has solved for customers on a consulting basis. Many of the workshops are designed to initially provide incorrect answers or not converge so that the students learn the skills to solve problems on their own after attending the course. Six of the workshops provide minimal instruction so that students can begin testing their skills under the supervision of an instructor during the course.

Prerequisites for this course are DRD’s Introduction to Mechanical course and practice gaining proficiency with Mechanical. DRD recommends that students who do not have these prerequisites delay attending the course until they attain them. This is a challenging course for proficient users.
