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

gslee

Hi,

 

I want to know contact force at each slave node or master segment.

 

In /TH/INTER, I can check only the sum of contact force in contact interface.

 

How can I check the contact force at each node?

 

Thanks.

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.
