You have two (2) options:

 

1 ) Create a constraint at the nodes in the TX, TY and TZ directions and apply an enforced displacement load to those same nodes.

 

2) With Femap v11.4 and later, you can assign a Non-Zero Constraint.

Hey Fricke,

I noticed the Non-Zero Constraint Option in Femap 11.4, how does that work? Your option 1 is on the only way I have ever seen it done.
Does it write out a SPC and SPCD ?
How's the load case dealt with In Analysis Manager?

Non-zero constraints are contained in a Constraint Set, not Load Sets.

I miss understood the meaning..  We used SPCD cards in the past for enforced displacement, which the drive node/grid had to be SPC inaddition to SPCD.  SPC used the SPC SET and the SPCD the LOAD SET.  I forgot about the SPC having a value being assigned for displacement.   Your right in the case of a pure SPC enforced displacement a SPC would show up in the SPC SET.
