Hi :)

I have two questions.

 

First, I want to know what is difference between 'Reaction force' and 'Reaction resultant'

In Ansys Help, Reaction force is used for constraints and Reaction resultant is used to know reaction force of support.

Which one is constraint?? I can't understand the Ansys Help's descriptions..

So, please describes me clearly about difference of them.

 

Second, how can I get joint or contact reaction force?

I thought that reaction force(Monitors->Reaction force) is collect, but when I use reaction force tool, it shows me a error message. 

I want to know that is it possible to get joint or contact reaction force?

And, what is the way to see them.

 

Best Regard,

Jugyeong Shin

Hello JUGYEONG SHIN  

First, I want to know what is difference between 'Reaction force' and 'Reaction resultant

The Reaction Force is a distributed result across the face of the support whereas, the Reaction Resultant is the sum of the forces across the entire geometric face. When multiple supports are used, a better judgement of how the force be distributed can be gauged using reaction force  plots. For the following case, If you have multiple faces in a support condition (as shown above) then you may see that the Reaction Resultant looks like a different solid color for each face (and the force distribution is over the entire support, showing which support takes more load),  Whereas the Reaction Force looks like a more continuous gradient of color across all the associated faces (to show how it is distributed over one support).

 Contact and joint  reaction force is not yet possible in Discovery.

Regards.
