How to check contact force at each slave node or master segment??

Hi,

You can view the contact forces at nodes in the animation output file requesting vector output in the engine file,

/ANIM/VECT/CONT

/ANIM/VECT/PCONT

Where CONT gives you the vector contact force in x, y, z at the node.

PCONT gives you a 'pressure' output in the normal and tangential directions by summing the contact forces applied to the node and dividing by the extrapolated surface of segments connected to the node.

Thanks,

Oh, I can check the time data in .h3d file. 

Is there any way to check the time history of the node in contact using /TH ??

Thanks

NO, the /TH outputs the total force for all the nodes in the contact interface. 

You can read the *A001 or *.h3d files in HG and plot the results.  The downside is if you want the results frequently you will need to output a lot of animation output.

What are you looking to do with this output?

Thanks,

Andy

Thank you for your answer.

I want to know when the contact and impact on interface occurs on which node. So I try to check the contact force on each node.

In your answer, I have to obtain a lot of animation output.

Thanks.
