Electroforming simulations based on the level set method
This paper proposes a general applicable numerical
algorithm for the simulation of two dimensional electrode shape
changes during electroforming processes. The computational model
consists of two coupled problems: electrode shape change rate
computation and a moving boundary problem. The innovative aspect is
that the electrode shape is computed over a number of predefined
time steps by convection of its surface proportional with and in the
direction of the local growth rate. Validation of the electrode
growth algorithm is made by comparison with experimental results
obtained for the electrode growth in the vicinity of a singularity
(incident angle between the electrode and insulator = 180°).
Finally an example related to the plating of two adjacent wires in
order to demonstrate the strong features of the applied method will
be presented
