Simulation of the shearbox

Asked by Felipe

Hello Everybody,

I am having some issues about simulation of the shear box. When the surface was moving down, the motion is not constant. It's sounds like leaps in motion.

I have tried to change all my script to build the same program with different ways. However, the result was the same. I was wondering if anyone could help me to understand what is happening.

I am sharing one video which was produced at the ParaView (version 5.0.1) were simulated on Ubuntu 16.04 LTS.

https://www.dropbox.com/sh/yu6crs6d4bpu996/AACeT41RsvgpBPmJkcX2gr7ra?dl=0

The best motion will be moving down constantly and when the surface gets either the correct position or apply stress, the box is going to move right, like shear motion.

Do Anyone have any idea to solve this problem?

Hope getting a solution about this problem.

Best Regards,

Felipe

Hi Felipe,
there might be several reasons, please provide a MWE [1].
Additionally please specify:
- more in detail what you would like to achieve (e.g. I **assume** constant
motion=motion at constant velocity)
- how the requirements differs from actual simulation (not important with
MWE as anybody can try the provided script).
thanks
Jan

PS: from the videos made from just a few pictures, it is not possible to
see anything :-)
