  1. hi, ich want to optimize the density of the concrete plates in OptiStruct. The Variablen are just only five type density of Materials (rho1 rho2 rho3 rho4 rho5), constrain: von mies stress sigma: sigma = 0.01*density objekt: Weightoptimization. how can i define the density variablen and constrain in OptiStruct? Best Regards, leslie
  2. Hi Guys, i have a question, how can i define Deflection - Condition for truss in HW ? Best Regards, Leslie
  3. Prakash Pagadala with optiSlang/iSight/ i can import excel-datei for this Typ desvar (of course solver is ansys ^ ^)
  4. Prakash Pagadala at first i define not the Function, i want to define desvar b und h, the 2 variable have no relationship, something is impossible, but not easy b =: 2, 4, 6,21,33,44: h =: 7, 9, 4,20,40,80; if b = 21 -> h= 40 if b = 33 -> h= 20 if b = 44 -> h= 88 if b = 2 -> h= 9 if b = 4 -> h= 4 if b = 6 -> h= 7
  5. Hi Guys, i define not the Function, i want to define desvar b und h, the 2 variable have no relationship, b =: 2, 4, 6,21,33,44: h =: 7, 9, 4,20,40,80; if b = 21 -> h= 40 if b = 33 -> h= 20 if b = 44 -> h= 88 if b = 2 -> h= 9 if b = 4 -> h= 4 if b = 6 -> h= 7 How can i define this Typ Parameter in HW, (from excel import ???) Thanks VeryMuch! Leslie
  6. tinh thanks very much, if i want to define 3 Torsion Spring (x,y,z) for the same Node, i donot think, this way is useful
  7. tinh Thanks for your help, but i donot know, how to do step 7 in hw (edit card the CELAS1 )? 7) edit card the CELAS1 elems, set C=6
  8. tinh at first: two bar are connect with pin joint. second: later add a Torsion Spring to this pin joint !! i hope, u understanding what i mean!
  9. tinh thanks for your help! Can u tell me, how do u define the pin Joint between 2 bars, donot use pins a/b??? how do u define the Torstion Spring between 2 bars, use elas1 ??? i use HW-Panel, not code!
  10. Hallo Guys, i want to define a Pin-Joint with Torsion Spring (See the foto) at first: two bar are connected with pin joint. second: later add a Torsion Spring to this pin joint. Programming in Hw: for Pin Joint Bar A: pins a : 0 , pins b: 456 Bar B: pins a : 0 , pins b: 0 for torsion spring SPC: Dof4 : 400000 (NM) But this simulation runs wrong!! how can i define right pin joint with torsion spring for two bars???? Best Regards! Leslie
  11. Prakash Pagadala you means: Bar A: pin a : 0 pin b; 456 Bar B: pin a : 0 pin b; 0 what can i write in pin a/b, 123456?
  12. Hi Guys, i want to define a pin joint for 2 Bars in x-y-z coordinaten: for example: Bar A: pin a : 0 pin b; 456 Bar B: pin a : 456 pin b; 0 but it do not work at all for test problem Thanks very much!!! Leslie
  13. Prakash Pagadala i try both methoden, it always says: *** ERROR # 1000 *** in the input data: Incorrect data in field # 5. look at the new snapshot.
  14. Prakash Pagadala i use your methode (Spring as PELAS or PUSH1 or PUSH), but it says: *** See next message about line 55 from file: C:/Users/Leslie/Documents/HM31.fem "CELAS1 1 1 2 123456 1 123456" *** ERROR # 1000 *** in the input data: Incorrect data in field # 5.
