Hi Sara,

To get the forces for the rigid bodies you need to put it in time history. /TH/RBODY/thgroup_id. To perform the same in HyperCrash, select the rigid body>>right click and select data history>>yes.

In HyperGraph, select the T01 file from which you can plot the rigid body forces.

Hi @George P Johnson

 

Adding  /TH/RBODY/thgroup_id. will help to readout the overall force extracted from the Rigid body node ?

Hi,

Using /TH/RBODY you can extract the results in that rigid body elements.

If you want for that master node create a /TH/NODE output block for that node.

 

Please go through the Help menu on /TH/RBODY and /TH/NODE where all the outputs extracted are shown.

Hi ,

 

I have created output block /TH/NODE for the master node of the rigid body. But it is showing error as no variables has defined.

Hi,

Once the output block is defined give the variable number as 1 and put DEF as the variable so that all default outputs will be extracted.

Hi ,

 

Thanks and now its working fine. For TH/RIGIDBODY we are getting force at 3 directions. The resultant force was not mentioned at the output. How can i calculate/convert the same ?

Hi,

For /TH/RBODY you will get TF in results which is resultant force.
