I am a new user to optistruct and am looking at controll arm optimization. I am having problems with my input deck and in the .out file it is referenced as error 1063 with a message saying:

*** ERROR # 1063 in the input data:

ATTA must be 1-8 for RTYPE of DISP.

Detected while reading line 55 from file

C:/Work/Bentley/Arnage/Fr_CtrlArm_Lwr/Optistruct/Fr_ctrl_arm_opti1_split_const.fem:

'DRESP1 4 dispX DISP TX 10233'

After reading about this area of input in the Altair help and comparing it to a turorial based on topology optimization of a controll arm it appears as if this line follows the correct format however I am unable to get the optimization to run successfully. Is there an obvious error in the input or a way to bypass the problem?
