Dytran is designed to solve transient dynamic problems involving a high degree of nonlinearity. This seminar provides an introduction to the Lagrangian capabilities of Dytran. The primary emphasis is on how to use the program to solve engineering problems. The major capabilities of the program are covered in detail. The process of performing an analysis is discussed in its entirety, from initial modeling to the post processing of results. Hands-on workshops and example problems reinforce the material covered in the lectures. Advice is offered on modeling techniques, meshing, and evaluation of results. In addition, techniques to minimize the cost of analyses are discussed. By the end of the seminar, attendees should be able to apply Dytran to the solution of practical engineering problems in structural mechanics.
Pre-requisites:
Experience with a general-purpose finite element analysis application is recommended.
