hey all,

running an optimization task to a part, one of the design responses in 'eigenvalue from modal analysis'

after starting the job with all parameters set i get an error message.

the monitor says i need to change the SUBSTEP value from all to one eigenvalue.

my question is where is this option to change the SUBSTEP, as i have had no luck finding the command to do so

Pic of issue is attached

Thanks in advance for any help
