Prerequisites

The tutorial presents a simple case study with the purpose of demonstrating functionality in AquaSim.

It is assumed that the user is familiar with the basic principles of modelling and specifying material parameters in AquaEdit, as well as conducting analyses. If you are looking for an introduction to AquaSim we advise you to start with the Basic program tutorials.

Introduction

This tutorial presents the possibility to introduce nonlinear relation between force and strain in membranes in AquaSim.

Linear-elastic materials are the basis for AquaSim. However, nonlinear relations between force and strain can be introduced to component types such as membranes. Nonlinear elastic elements do not comply with Hooke’s law in such way that there is a linear relation between force and strain.

Having completed this tutorial, you will be able to:

• Know the basics of nonlinear tables in AquaSim
• Establish a simple model with a nonlinear membrane
• Evaluate and self-validate results in AquaView
