Moving singleGraph line with moving reference frame

MikeWorth · June 29, 2020, 15:32

I'm running a model, where I've used multiSolidBodyMotionSolver linearMotion to translate my mesh, which appears to be doing what I'd like; however it has broken my probe output.

I've got a singleGraph set up that reads a parameter along a fixed line, which slowly stops being useful as my mesh translates away, and there is eventually no overlap between the line and my mesh. At this point it doesn't give any useful output.

Is there a way to either configure singlegraph to move with the mesh, or access the current time within my setup dict so and use this to calculate moving co-ordinates for the line?

Thanks,
Mike

I've come up with a crude method, which sort of works but not very efficiently - have a very long line that extends far beyond the mesh, and translate the mesh parallel to this line.

I tried using face, midPoint and midPointAndFace, but they all missed out a load of mesh elements, leaving me with defining a huge uniform set of points, most of which miss my mesh.

It's giving me the output I want, but seems to be slowing down my solving substantially. Does anyone have a better suggestion?
