how to simulate gears in catia?
I have modelled two gears. How do I mesh constrain them and simulate them in catia?
CATIA - DMU Kinematics Gearbox WIP
Spur Gear Simulation in Catia V5 DMU Kinematics
and this could be useful before starting simulation!
Do you mean FEM simulation or kinematic? If you want kinematic simulation you should use DMU Kinematics module (Digital Mockup). You have to make new mechanism, add properly joins, if you restrict the degrees of freedom, Catia will inform that mechanism can be simulated.
