Has anyone here tried to use ALLKE as a sensor with VUAMP in Abaqus. There is precious little in the manual about what you can and can't use as a sensor, but it seems to throw an error.

As *energy output isn't listed as an example I am guessing this isn't supported. Any ideas of work around? Basically, we want to trigger an event in the model with the kinetic energy of the system gets to specific level.
