Hello community,
I have the following problem when I try to simulate a drilling technique with a drill head rotating only
around the vertical axis not doing any movement (up or down) at all.
The job only runs for a very small rotational velocity and if I try the same problem for a
higher value I get the following error:
'The ratio of deformation speed to wave speed exceeds 1.0000 in at least one element. This usually indicates an error with the model definition. Additional diagnostic information may be found in the message file.'
Below I attach the data for the step time, amplitude and the boundary condition in which the rotational velocity is (and I suspect my mistake is on this data):
And my results for the very small rotational velocity are as follows:
