Introduction

A three-dimensional model of intersecting pipes is provided. Quarter symmetry is assumed. The goal is to mesh the part with hexahedral elements. You will partition the model into 3 regions and mesh all the regions with hexahedral elements. You will then create tie connections between the meshes.

After completing this workshop, you will be able to:

Import a 3D XML file into the 3DEXPERIENCE Platform.
Create volumes.
Organize different surface and volume entities in geometrical sets.
Create hexahedral elements.
Create tie connections.

Exercise Process

The overall process that is involved in importing and partitioning the geometry is summarized below.

Narrated Video

The process of importing and partitioning the geometry is described in this narrated video.

0:00 - 6:19 (What are volumes, how to organize surfaces and volumes in the specification tree, how to create a FEM Rep and how to switch to the Simulation Model Preparation app).

6:20 - 22:30 (How to create partitions).

22:31 - 26:28 (Meshing the different volumes using hex elements).

26:29 - 29:08 (How to create Tie connections between different volumes to avoid rapid mesh transition)

29:09 - 29:50 (Q&A - Tie connection)

29:51 - 35:20 (Q&A - Relation between volumes and solid in the PartBody)
