Hello everyone!

This tutorial will teach you how to set up a simulation using the Physics apps in the 3DEXPERIENCE Platform. We will be considering an example of a basketball hoop assembly to demonstrate different features in the Physics apps.

This tutorial was created using 3DEXPERIENCE 2015x.

Problem Statement

The problem is to simulate a scenario where a basketball player performs a dunk and then grabs and releases the hoop/ring on the way down.

The model consists of two parts - a backboard and a basketball rim. One end of the backboard is in contact with the rim and the other end is fixed. A pressure load is applied to a small section of the rim, thereby causing it to deflect.

Two workflows are discussed in this tutorial:

1. To tie the backboard and the hoop together and then apply a load to a small section of the ring thereby causing a deflection (Scenario 1).

2. To introduce virtual bolts to connect the backboard and the hoop together, define contact between the surfaces of the backboard and the hoop and then apply a load to a small section of the ring thereby causing a deflection (Scenario 2).

The two above scenarios will try to simulate a part of the actual problem statement - a scenario where the player hangs from the hoop after the dunk. Since both the above discussed scenarios are static events, they will be run as static analyses.

A summary of the problem statement and the objectives are also available as a narrated video.

A third scenario will be simulated where the dynamic events of the problem will be considered, i.e., the vibrations of the ring will be captured after the pressure load is applied and released.

Objectives

When you complete the tutorial, you will be able to

• Navigate between different apps to create a FE model.
• Create simple simulations and submit it for analysis.
• View the analysis results.

Below is a table that provides you with a link to the posts that contain tutorials illustrating the above-mentioned scenarios.

1. Scenario 1: The assembly consists of two parts - a backboard and a hoop. The hoop and the backboard are tied together. A pressure load is applied to a small section of the ring which causes it to deflect.
2. Scenario 2: The assembly consists of two parts - a backboard and a hoop. Virtual bolts are introduced such that the backboard and the hoop are bolted together. A scenario with multiple static steps is created. The bolts are pre-tensioned in the first step. A pressure load is applied to a small section of the ring in the second step. A contact pair is defined between the surfaces of the backboard and the hoop that are in contact with each other.
3. Scenario 3: The assembly consists of two parts - a backboard and a hoop. Virtual bolts are introduced such that the backboard and the hoop are tied together. A scenario with multiple static steps is created. The first step is a static step where the backboard is clamped and a pressure load is applied to a section of the ring. The second step is an implicit dynamics step where the pressure load is removed and the ring will vibrate due to the removal of the load.
