Main Question or Discussion Point

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...

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