Problem of rigid body surface

[Engelien01]

I define a 4 parts model tower. On the ends are rigid bodies and in the midle are deformable ones. I started already with 3 part model, but now I get always the ERROR message:

"The slave surface assambly_pickedup32 cannot be rigid." (That is the surface of top rigid body.)

What does the message mean exactly?

thanks

As far as I know rigid surfaces must be always the master surface in a contact definition. try it

Thanks - I had to change all surface-to-surface combinations, that aba accept my change to master.
