Hi,

the CB and CC methods are used for generating flexible bodies for use with some Multibody dynamics solvers, like MotionSolve. The CBN method can be used to generate CMS superelement information for some third-party solvers

Hi,

 

I think CB comes with free free and constrained but CBN is not. 

 

13.0 is very old. You can search for the tutorial with same title

if you remove the ASET you should get the same number of modes as specified in NMODES.

 

The extra modes are the number of FEM DOF that are in the interface.

OK, If you are using other than CBN and GYUAN, the number of modes without ASET is equal to what you get.

Hello,

 

I need help!

I am working in optistruct and have used CBN method to make flexbody. I need to use the file in SIMPACK for MBS. Can anyone tell me, how to generate fbi format in hypermesh.

 

Thanks in advance
