Level Set Solution of an Inverse Electromagnetic Casting Problem Using Topological Analysis
نویسندگان
چکیده
In this communications we present an algorithm to solve an inverse electromagnetic casting problem. We look for a suitable set of electric wires such that the electromagnetic field induced by an alternating current passing through them makes a given mass of liquid metal acquire a predefined shape. The inverse electromagnetic casting problem is formulated as an optimization problem using a shape functional based on the Kohn-Vogelius criterion. The numerical level set method proposed is defined by means of second order topological asymptotic analysis. Numerical examples are presented showing that the proposed technique is effective to design suitable inductors.
