Microrobot simulation

Post by monty_blue »

Hello,

I am wanting to simulate a magnetic microrobot that is reconfigurable. Basically, the robot consists of two pieces that open and close in response to a cyclic magnetic field. It works just like a scallop, so I was just wanting to see if anyone here might know how to create a mesh consisting of two pieces and something like a hinge. I am an experimentalist, so I was having trouble getting started on this front.

Thanks!

Hi

So you would need a moving mesh? Maybe you can provide a picture.

Here's one picture from an ANSYS simulation done by a coworker.

Do I understand correctly that the region between gets fully closed?

This kind of adaptivity is not supported. We do have mortar BCs that could be used for rotating entities, but not for this kind of on-off thing? Can you do several predefined meshes?

Yes, the region between fully closes. It's supposed to open and close like a scallop, so each half would rotate about a hinge.

I assume that there are no history effects? Then you maybe could make a series of meshes with different distances. We do have mesh stretching but that does not work with complete open/close. Elmer has been used in magnetic lifting but the movement adds one layer of challenge. -Peter
