Hello @QuickLearner,You could definitely do a belt pulley simulation in ANSYS using transient structural analysis. Here is a tutorial that you could follow

The belt tension could be varied by displacing one pulley with respect to the other. You could use a displacement constraint to do this.Regards,Ishan.https://forum.ansys.com/discussion/comment/108726#Comment_108726

Thank you Ishan. But is it possible to visualize the effects of change in belt tension such as decreased speed of rotation of the pulleys or change in the frictional force between pullet and belt etc. Would be great if you could throw some light on these aspects.
