Defining cooling channels

In design projects, if your model contains cooling channels, you must define the components that represent them so the solver can identify them.

You can categorize the cooling channels in your mold using one of the following approaches depending on the cooling channel definition in your model:

  • If your mold contains cooling channels modeled as explicit physical bodies, you can categorize them using the Bodies selection mode. This mode lets you select the cooling channel bodies directly from the CAD model to assign them to the channel card category.
  • If the cooling channels are drilled into your mold and are not modeled with physical bodies, you can extract them directly from the mold using the Faces selection mode. This mode lets you select a channel surface, and it automatically creates a channel body by connecting cylindrical channels that are connected to the selected surface with the same color.

To complete the channels definition, you specify the channel surfaces that define the inlet and outlet for the cooling liquid. You can use channels with one inlet and multiple outlets.

Defining baffles

The software allows to automatically categorize the baffles included in the channel region. Baffles must be fully enclosed, except for the inlet and outlet. The software attempts to close any other gaps. In cases where the baffle geometry is unconventional or the baffle is not included in the channel selection, automatic detection may not categorize baffles correctly. In such cases, you can edit, repair, or add the baffles manually.

The detect baffles automatically mode is enabled by default. You can disable it to prevent the automatic categorization of baffles.

Channel color-coding guide

SimForm uses color-coding to help you verify channel definitions. The following table summarizes the color code used for channels.

Color Description Example
Gray Indicates a channel assigned to the Channels card.
A gray U form cooling channel.
Turquoise Indicates a categorized baffle.
A gray U form cooling channel with six turquoise baffles.
Purple Indicates a channel inlet surface.
A red U form cooling channel with a blue surface indicating the channel inlet.
Red Indicates a channel with a defined inlet but no outlet. You must define the channel outlet.
Green Indicates a channel outlet surface.
A yellow U form cooling channel with a green surface indicating the channel outlet.
Yellow Indicates a channel with a defined outlet but no inlet. You must define the channel inlet.
Blue Indicates a channel with defined inlet and outlets.
A blue U form cooling channel with a blue surface indicating the channel inlet and a green surface indicating the channel outlet.
