Questions about the keywords DEFORMABLE-TO-RIGID-AUTOMATIC and CNRB

      Hello, we are currently working on a case where component 1 and component 2 are connected through"Rigid_body" and rotated around point A (see Figure 1). Using the key "DEFORMABLE-TO-RIGID-AUTOMATIC" will result in a node error (see Figure 2), and using the keyword "NBRF" has no effect(see Figure 3), still prompting a node error. May I ask if there is a problem with the keyword itself, or is it using the wrong method? Keywords can be found in the attachment.

      Hello Mei,

      I cannot see the images you posted; it seems they failed to load. Could you try to post the images again?

       

      Reno.
