Once you have created channel curves and assigned the correct properties to them, they must be meshed.
Click
(Mesh tab > Mesh panel > Generate Mesh).
The
Generate Mesh dialog appears. Notice the
Global edge length on surface is already defined. This is the global edge length that will be applied to the model and will probably not be appropriate for the channel edge length.
Click the
Curves tab.
The value entered for the
Edge length vs. diameter for Circuits will be used to determine the channel edge length. The default value of 2.5 indicates an edge length 2.5 times longer than the diameter of the channel.
Click
Mesh Now.
Note: Complex cooling channels may require both the inlet and outlet defined for a Cool analysis to run.
