In this workshop, you will import a part into the 3DEXPERIENCE Platform. The CAD data represent a lens

component provided in STP format. After importing the part, you will create a Finite Element Model

Representation and mesh the lens component. You will then check the quality of the lens mesh. To improve the

mesh, you will defeature the model. You will then update the mesh and check its quality.

After completing this exercise, you will be able to:

a. Import a neutral format CAD file.

b. Create a Finite Element Model Representation.

c. Mesh the geometry and check its quality.

d. Use the Simulation Model Preparation app to defeature the model

A three-dimensional model of intersecting pipes is

provided. Quarter symmetry is assumed. The goal is to

mesh the part with a combination of hexahedral and

tetrahedral elements. You will partition the model into 3

regions and mesh 2 regions with hex elements and the

third with tet elements. You will then create tie

connections between the meshes.


a. Import a 3D XML file into the

3DEXPERIENCE Platform

b. Create volumes.

c. Organize different surface and volume

entities in geometrical sets.

d. Create hexahedral elements and tetrahedral

elements.
