data set not kinematically determinate
data set not kinematically determinate
(OP)
Dear members,
I've a chain with many parts connected with joints (spherical, revolute, cylindrical).
I've imposed motion on some of them, so my system has one DOF(verified).
Input and output members are connected with 2 point-curve constraint to move on 2 paths.
Dynamic simulation is ok.
I reach what I want.
But I like to perform only a kinematic simulation, with no mass and inertias involved.
When I set kinematic simulation, I receive this error message:
ERROR: The data set is not kinematically determinate, yet a kinematic analysis
has been requested. STATICS and DYNAMICS are two possible choices for
the analysis mode. KINEMATICS is not valid in this context.
I hope somebody can help me...
Many thanks!
Francio

RE: data set not kinematically determinate
So I sobstituted the pctv joints with spherical joints and translational joints, and put a motion on the input translational joint.
The result is the same, but with pctv it didn't work.
I don't wnow why...
