RIGID BODIES AGAIN

[PQF]

Does anyone know how to make a rigid body out of an imported orphan mesh ?

Unless someone has a clever answer of meshing the outside with rigid elements, you could always make the properties of the part very stiff by using a very high Young's Modulus.

I know you can convert the solid mesh into shield mesh.

Wonder if you can then change the shield elements into R3D4 elements in keywords.

Hoever, I haven't tried it myself, it is just an idea.

Opp spelling mistake..

*Shell not shield

yoman228 is right. you can change element formulation in abaqus input file

Hi,
put the elements in a set and use the *RIGID BODY utility, I don't exactly remember the syntax, but its very straight forward. Check the manuals.

Hi again this is how you should do:
1. Put all of the elements in one element set: *ELSET,ELSET=ORPHAN_MESH_TO_RIGID
el1, el2, ...,eln etc.

2. Use the *RIGID BODY facility:
*RIGID BODY, REF NODE=NNNN, ELSET=ORPHAN_MESH_TO_RIGID

(NNNN is a reference node for the rigid body)

And then you have yout rigid body.
