In transient analysis of electromagnets, I need to provide a sinusoidal source. I am able to give the current density at the node but unable to add frequency as input. I am using GUI for my simulation in ANSYS.
1. use the coupled field analysis. finite elements like plane53, solid97 can be coupled with the circuit element circu124. you can define the AC voltage source in the circuit. see Low-Frequency Electromagnetic Analysis Guide and Coupled-Field Analysis Guide for details.
2. define an array and use the array as your excitation. the first row of the array is the time, the second row is the corresponding current of the specific time. see "8.4. Example: Transient Magnetic Field in a Conducting Block" in Low-Frequency Electromagnetic Analysis Guide for details.
