Problem Type
Axisymmetric problem of transient magnetics coupled to transient magnetics.
Coil is uniformly wound by thin wire, with total ampere-turns following the triangle wave function shown on this diagram:
Simulate first 3 seconds of the transient process.
Simulation is performed by 3 separate transient magnetic analysis problems covering stages of the process one second each. They share the same geometry model, and are connected by Magnetic Field coupling mechanism. The magnetic field at the end of Stage 1 is coupled to Stage 2 as the initial magnetic field of Stage 2. Magnetic field at the end of the Stage 2 is coupled to Stage 3.
