Hi Lokesh Katari

 

Rigid bodies are ideal representations of solid bodies or parts of fixed shape and size. They are highly useful in simulations where deformation of a part is negligible. A rigid body has 6 DOF, and each rigid body added to a system adds an additional 6 DOF.

 

Flexible bodies, or flex bodies, are used to model elastic deformation of bodies in a system. The flex body connects to its neighboring elements and bodies through interface nodes.

why we are creating flex bodies?

 

Because to estimate internal response (like stress) for the applied external loads

Sir is there any methods which are similar to modal analysis??

if there please list it out

Not sure what you mean by methods similar to modal analysis?

Hi LOKESH KATARI,


flexible bodies are created with modal analysis of each component, so it will output natural frequencies (in .h3D and .out files).

If your query is about performing modal analysis on flexible body assembly, you may find useful:

Hi,

 

SPID_INIT is the Starting point ID(SPOINT) for sorting the modal data. 

 

SPOINT entries are useful to define scalar points in constraint equations but to which no structural elements are connected.
