Magnetic heating

A new addition to Flo++ is the solution of electrical and magnetic fields. The example below shows heat transfer in a electrical conductor. Heat sources due to the environment, electrical current flow, as well as magnetic heating are taken into account. 

Figure 1 below shows the layout of a typical multi layer multi strand conductor - each layer being twisted in opposite directions. Figure 2 shows the complex air pockets between the strands.

Figure 3 shows a portion of the computational mesh. Arbitrary mesh coupling is used to couple the arbitrary overlapping mesh interfaces.

Figure 4 shows a typical temperature profile through the conductor.

of meshing the strand and air regions.
