Reply To: Need help with moving heat source on uneven surface with apdl

Hi Dave

In the end, the Topheadlaser should move along a Lissajoux-Figure centered on the top of a single tooth. I have tried to position the laser by adding and subtracting from the centrx/centry/centrz commands without success. The velocity of the laser along the surface is linked to the power of the laser to combat temperature extremes at the edges of the lissajoux-figures. Do you know per chance what the marked *do-section would need to move along the surface of the gear? 

As the Lissajoux Figures only have an amplitude of about 1mm it should stay on the top of the tooth and not need to incorporate movement up and down the tooth. (Or so i thought)

Concering the heat generation rate, i tried to link it to a fixed radius, which i define at the beginning of the code as “rmax” to control the area where the heat is being applied. This somehow seemed to work in a previous project with no corelation to the element size. Do you this is gonna be a Problem in this geometry?
