Controlling a 3d path of a rigid body?
Controlling a 3d path of a rigid body?
(OP)
Hi all,
I am looking at simulating a process and require to control the path of a rigid body. Only translational movement is required. It will be along a path defined by unevenly spaced points, at a constant velocity.
Does anyone know how this can be achieved?
Thanks

Thanks for the reply Rob. The issue is the path is quite complex. I was hoping that there was perhaps a function available to perform a complex displacement in a single step. The closest I have seen is the user function vdisp. Where I could write a function to input text files of the displacements and generate the displacement output for the RB reference point.
Although I havnt used user defined functions in abaqus before and I'm not really sure what is required.
Does anyone have any tips or possibly info on how to set up such a user function to read in points from a file and set positions. Along with utalising the vdisp in the inp file.
Thanks again
