COOLING DUCT LOCATION DURING OPTIMIZATION

Cooling duct location during optimization – we are still unclear on what occurs to ducts during this process.  In the transformer program, it appears that their number and location is inputted.  In optimization, it appears that their number is defined, but not their location – is this correct?

In Transformer we specify how many different locations duct are going to be present, for example: a winding with 4 layers and 2 location of ducts the program place the ducts between layer 1 and 2 and layer 2 and 3.

In Optimization we specify how many different locations duct are going to be present – the same as Transformer in example above if during optimization the number of the layers may drop to 2 then although you specify 2 locations optimization will reduce the number of locations to 1. If the number of the layers during the optimization for this example increased to let’s say 6 layers optimization will continue to consider only 2 locations for ducting.
