Hi, I must perform a TRANSIENT DIRECT ANALYSIS in Optistruct.
I have to give a linearly increasing acceleration up to a constant value to the structure (equal to 20g --> GRAV load) in the constrained zone (like an earthquake). For TSTEP and TABLED1, i ve no problem. I ve setting the parameters on the TLOAD1 card like in the attached figure, but my analysis don' t run.
This is the error:
*** ERROR # 2094 ***
EXCITEID on TLOAD1 # 4 data references nonexistent
SPCD # 5.
************************************************************************
A fatal error has been detected during input processing:
*** ERROR # 2094 ***
EXCITEID on TLOAD1 # 4 data references nonexistent
SPCD # 5.
Where am I doing wrong ?
