I changed a spring element to link11 actuator element in a command object and defined an axial
force to the actuator.

Spring object:

Code:

actuator = _sid
ET,actuator,11
R,actuator,1000,,10 !stiffness 1000, mass 10

Environment branch:

Code:

SFE,2431,2,PRES,0,1000 !2431 is the element number, axial force 1000

Solution branch:

Code:

ESEL,S,ENAME,,LINK11
ETAB,CYLFORCE,SMISC,1
PRET,CYLFORCE

I am getting the following message in the output file. How can I get the force in the actuator?

SELECT FOR ITEM=ENAM COMPONENT=
IN RANGE 11 TO 11 STEP 1

1 ELEMENTS (OF 1623 DEFINED) SELECTED BY ESEL COMMAND.

STORE CYLFORCE FROM ITEM=SMIS COMP= 1 FOR ALL SELECTED ELEMENTS

*** WARNING *** CP = 1.047 TIME= 02:08:22
The requested database is not available. The ETAB command is ignored.

PRINT ELEMENT TABLE ITEMS PER ELEMENT

*** WARNING *** CP = 1.047 TIME= 02:08:22
No element table items are available. The PRETAB command is ignored.

Is this the actual code snippet you are using?

This should work if you put in the solution branch of Mechanical:

Code:

/POST1
RESUME,FILE,DB
SET,LAST
ESEL,S,ENAME,,11
ETABLE,FORCE,SMISC,1
PRET,FORCE

I edited the original post to show the location of the code lines in the tree structure. Is there something funky?
It seems to be working as expected not taking into account the actuator force table.

Your suggestion seems to be working,thanks!

I think the only thing funky is in the solution branch of your snippets. You have to resume the database and then select a result set. That is done in line 2-3 of my snippet.
