MX-1030

In this tutorial, you will learn how to:

•	Load a HyperMesh file containing solid mesh of the part and the runner and geometry of coolant channel and moldbase

•	Create mesh for the coolant channel and moldbase

•	Assign property card(s) to the part and the runner

•	Assign property card to the moldbase surface mesh

•	Create the coolant channel

•	Define melt entrance boundary condition

•	Export the model as a Moldex3D MFE file

In fast cool analysis, the meshes for moldbase, coolant channel and mold insert are not solid meshes. Mesh for coolant channel is a 1D mesh. Meshes for moldbase and mold insert are surface meshes. Meshes for part and runner are solid meshes.

The model files for this tutorial are located in the file mfs-1.zip in the subdirectory \HyperMold\Moldex3D\MX_1030. 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.
