MX-0020: Setting up an MSH Model with Part Using Thickness Extraction

In this tutorial, you will learn how to:

•	Load Moldex3D/Shell user profile

•	Load a HyperMesh file containing geometry of a part

•	Extract midsurface from the part geometry

•	Mesh the part

•	Assign property card(s) to the part

•	Inspect mesh quality and thickness contour

•	Define melt entrance boundary condition

•	Export the model as a Moldex3D MSH file

The model files for this tutorial are located in the file mfs-1.zip in the subdirectory \HyperMold\Moldex3D\MX_0020. See Accessing Model Files.

To work on this tutorial, it is recommended that you copy this folder to your local hard drive where you store your HyperXtrude data, for example, “C:\Users\Moldex3D\” on a Windows machine. This will enable you to edit and modify these files without affecting the original data. In addition, it is best to keep the data on a local disk attached to the machine to improve the I/O performance of the software.
