Introduction To Dytran

5/6 Day Course - Pretoria

COURSE INFORMATION

Description

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 modelling to the post-processing of results. Hands-on workshops and example problems reinforce the material covered in the lectures. Advice is offered on modelling 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.

  • Introduction

ABOUT THE PRESENTERS

PREREQUISITES

  • Experience with a general-purpose finite element analysis application is recommended
  • An engineering understanding of strength of materials are required as a minimum to reap the most benefits from the course.
  • Attendees should indicate their software preference before hand although most courses might be scheduled for a specific product to be used.
  • If the attendees will be using software not supplied by SIMTEQ, they should bring their own computers with their licensed software installed and activated on it.
  • More information is available on request for users of non-SIMTEQ supplied software to ensure they have the correct functional knowledge of their software user interfaces to complete the provided exercises unassisted.

WHAT OUR CUSTOMERS SAY

  • "The friendliness of the instructors and the rest of the staff was exceptional. The training was thorough and covered a lot of key aspects to kick-start one into efficient usage of NX within the time of training.
    The lessons were engaging and to-the-point.    PS: The food was very good as well.    " - Theo van der Berg, WJ Engineering
  • "The course is well presented. I also enjoy the focus on the limitation of FEM.It was one of the better courses I've attended in recent years." - Jannie Potgieter, Booyco Egnineering
  • "Excellent course. Gives the basics of FEM and the possible shortfalls." - Mohamed Jogiat, Transnet
