Transient FEM Simulation of a Solenoid Actuator with MAXWELL

  1. May 27, 2015 #1
    Hey Guys!

    Hi Guys!

    Well I am new here and I have to confess that I somehow got stuck in a 3D transient electromagnetic simulation of a solenoid actuator and… I’m a mechanical engineer^^ So I would appreciate some help of you guys!

    1. I imported the geometry from CAD-files. But I remodeled the coil and the plunger with a sweep of the section around the z-axies.


    2. I added a vacuum Band around the plunger

    3. I setup the motion with:

    4. I added some meshing options

    5. I added a winding and a coilterminal with an external circuit


    6. I setup the Solution:


    7. I solved it

    So the solving went smooth but the mesh is not very refined jet. I get a Force acting on the plunger but the speed and the position of the plunger they don’t change...

    And here are the xy plots:

    It somehow seems to be a problem with the movement. The moving vector has to be positive apparently. I will keep you posted
