Introduction – Remote Loading • The ANSYS Workbench represents more than a general purpose engineering tool. – It provides a highly integrated engineering simulation platform. – Supports multiple multi-physics engineering solutions. – Provides bi-directional parametric associativity with most available CAD systems. • This exercise is designed to introduce you to the use of “Remote Loads and Masses” and “Combined Results” in the ANSYS Workbench

Purpose • This tutorial is incremental in nature • It is designed to introduce you to: – The nature and design of the ANSYS Workbench User Interface – The concepts of ANSYS Workbench Projects and Applets – The integrated nature of ANSYS Workbench technology – The power of the ANSYS Workbench in using applied parametric modeling and simulation techniques to provide quality engineering solutions

Using “Mass Points” • The methods taught in this tutorial apply equally well to both attached CAD and DesignModeler files. • For the purposes of this tutorial we will be using the DesignModeler file produced in Exercise 3 of this tutorial. • When using attached CAD systems “Mass Points” can be attached to tagged entities import from from your CAD models.

Using “Remote Loads” • Remote loads can be attached to remote Mass Points and then be applied to active CAD or DesignModeler geometry. • These Mass Points and Remote loads can then be used in various combinations to solve an overall simulation.
