2. Load and Load Case in Akselos Modeler

Introduction

Creating loads and load cases is an essential step in modeling stage. A load in a simulation model represents the impact of an internal or external force applied to the model.

This article will provide users with more information about definition of Load Case and Load, what is needed for a Load, and how to create a Load Case with Load in Akselos Modeler.

Add Load Cases is a part of the Modeling steps in Akselos Workflow to build any simulation model.

Terminologies

Subdomain	A group of mesh elements having the same properties (materials or other common properties) inside a component
Components	Components created by the componentization process to use with Akselos Integra
Sideset	A surface of mesh assigned with a certain ID number
Solid component	A component containing only solid elements
Shell component	A component containing only shell elements

Load and Load Case in Akselos Modeler

Applying loads to Akselos model is an indispensable part of setting model. In Akselos Modeler, forces, moments or pressure will be set as Loads in Load Cases , which are defined clearly as below.

The Load Cases and Loads features of Akselos Modeler allow the creation and configuration of all the relevant load scenarios for a particular asset. In Akselos Modeler:

A load refers to a particular force/moment/stress that it’s applied to a group of elements (components, volumes, surfaces, nodes) of the asset. There are different type of loads and each one has a unique set of parameters to be configured (described below)
A load case refers to a group of loads. Loads of different types can be grouped together within one load case. There is no limit in the number of load cases that can be created.

Figure 1. Load Cases and Loads are shown in the Load Cases branch of the Model tree

Conditions of a Load

In Akselos Modeler, the Load will be applied to a Stored Selection, so users need to finish creating Stored Selection(s) first – users can find how to Stored Selection in this article: Stored Selection

For different load types, the target (component/ subdomain/ element/ surface) need to have operator of that load - see Exploring tool to Edit component - How to add new load surface as a reference of adding operator.

How to Create Load Case and Load

Load Case and Load are created directly on Akselos Modeler, users can follow the below step to create a completed Load for a Load Case.

STEP 1: Create Load Case

To create a new load case, right-click on the Load Cases branch of the Model tree then select Create Load Case.

The New Load Case / Load dialog appear
- Select Load Case that the new Load will be located
- Set filter adapt to the target for easy selecting

Select a Load Type and click Save button to complete the Creating Load.

Users can also Clone – Move/Clone – Rename – Delete the load after right-clicking on it.

STEP 3: Create Load Case

Click on Point Load 1 and go to Properties Panel for the next steps.
On the Properties Tree, users need to select the Stored Selection for the load → modify Load Parameters to complete setting a load.

Figure 7. Set Load properties

The setting properties for specific Load type can be found on the article of that load.
