  1. Thank you!! It helped me to solve another model with similar error. But, now this analysis shows following error: *** ERROR # 2985 *** Dependent DOF 2 of GRID 9321 cannot be converted to an independent DOF with AUTOMSET for this rigid configuration. There are not enough constraint equations to reformulate it. If RBODY is used in the model, it is getting overconstraint in the model. By adding "DEBUG,REMOVRGD,1.", Optistruct would not create constraint on the dependend node of RBODY.
  2. Hi Simon Kriznik, Above file run perfectly. I tried to run with mine and curve starting with 0,360. It shows following error. *** ERROR # 3002 *** The first point (X1,Y1) specified on the TABLES1 bulk data entry ID=6 is not located at the origin of the stress-strain curve. so, that is why I changed the first row to 0,0. What is the meaning of this error.
  3. *** ERROR # 3010 *** The xi specified on the TABLES1 bulk data entry ID=6 is not in ascending order. Table with plasticity curve: 0 0 0 306 0.0011 415 0.0022 445 0.003 461 0.004 474 0.0052 489 0.0061 498 0.0071 505 0.0081 512 0.009 522 0.0102 530 0.0121 543 0.013 550 0.014 555 0.015 561 0.0159 567 0.0171 572 0.0181 577 0.0204 592 0.0303 632 0.0405 663 0.0502 687 0.06 706 0.0702 722 0.0807 737 0.09 749 0.0997 758 0.101 759 0.11 768 0.15 805 0.2 840 0.3 900 0.5 1000 1 1210
  4. I have been doing a size optimization tutorial on a bike frame. Optimization objective is to minimize the mass. After following all the step which is given in the pdf, results are not correct. After optimization mass is supposed to reduce but it increased. What am I doing wrong?
