  1. Hi Hyperman, This tutorial is based on Non linear quasi static Analysis, can i do it using linear static analysis if it possible please the tutorial, i want to do pre tension analysis in linear static analysis because i have to apply two another linear static load on the model, if it is possible please do let me know, so that i can solve the issue. regards, Noor Alam
  2. Hello everyone, can anyone please share bolt pre tension test tutorial with modeling example. regards, Noor Alam
  3. THANK YOU VERY MUCH, for your support. i want to know for highly impact load (Initial velocity) which contact interface type will be preferable, if loading condition is similar to my model, Regards Noor Alam
  4. hi, if contact energy is going in negative, then what should i do, should run the simulation or cancel. because your corrected model has also negative energy error. i have little bit doubt is it give correct result or not. also please confirm should i used contact interface Type 7 and Type 19 together. which used by you in corrected model. or anyone contact interface type. please suggest. regards Noor Alam
  5. hi hyperman, As per your recommendation i have change the contact interface TYPE 7 to interface TYPE 11 but i am facing same kind of issue, for your reference i am attaching .hm, radioss exported file and .out, requesting you to pls check l and resolve the issue, pls send the corrected model. Regards Noor Alam

  7. Hello everyone, i am facing negative % ERROR in radioss, due to % error convergence issue is occurring. for reference i am attaching the .out file. pls let me know how can i resolve the issue. One thing i want add is this % error is occurring when ever i am using contact between master and slave component, i am sure there is no any penetration between slave and master.if i am simulating the problem without any contact , like directly applying load on component node, there is no issue occurring.for reference i am also attaching the snap shoot of contact assignment. regards radioss_0000.out
  8. Hello Hyperman, thanks for your reply, as per your as per your comment i have check all all the model,as i understand there is no any issue, but still i am face same problem, like % error is negative. for your reference i am attaching .out file, please let me know what is the issue of this error. radioss_0000.out
  9. hello Please let me know where output variable will be created , like which control card will be use for output variable create. Regards Noor Alam
  10. Hello Hyperman, i am doing rd 3500 tutorial during ran the tutorial, i am geting this eroor, please let me know why this error is coming, i am sending time history setup as well as error message screen shoot. regards Noor Alam
  11. Thanks Thanks, hyperman, i have one another issue , some time error % is going to very low which is highlighted in below, i am not aware why this is going very low, i also realised some time due to this my remaining time is increases, Please let me know if error % is negative then what its mean, Solution is going correct or wrong, if due to this solution is going wrong then what error should be there in model. regards, NOOR ALAM
  12. Hello Everyone, i am doing Non linear quasi static analysis using Radioss solver, Loading condition is Force ramp vs Time, but i am unable to find force vs Displacement graph and Time vs Displacement graph in Hypergraph by .T01 file. Can anyone please let me know which input control is used to find load vs displacement and time vs displacement graph. Regards Noor Alam.
  13. Hello Mr Rahul. Actually my analysis type is linear static analysis and my loading is cyclic loading because my model is automotive wheel rim. for this i am unable to find no of cycle vs load peak value (.cvs file) ,which is needed in FATDATA card image. For more detailed i am sharing to you tutorial .cvs data file, Please let me know how can i create .cvs file for my model. i am waiting for your valuable reply, Regards NOOR ALAM load1.csv load2.csv
  14. Hello everyone. i want to do fatigue analysis on our product using optistruct as a solver, my loading condition is sinusoidal, or cosine wave function, but i am not able create .cvs file (no of cycle vs load file) which is required in FATDATA cared image, please guide me how can i create the .cvs file (no of cycle vs load).and what formula used create the .cvs file. regards NOOR ALAM
  15. HI EVERYONE I AM DOING SIMPLE IMPACT PROBLEM USING TWO PLATE USING CONTACT B/W BOTH PLATE IS INTERFACE (TYPE 7).I CONSIDER ONE SLAVE AT WHICH I HAVE APPLIED INITIAL VELOCITY 100 MM/sec.Termination time is .4 sec.time step is 9.73e-7 sec (element size is 5 mm for steel mat).plate 1 have applied initial velocity and plate 2 size edge is fixed by spc. but i am getting this type of error.which is in below. ** ERROR IN INPUT FORMAT ERROR id : 266 INPUT VERSION 2018 IS NOT SUPPORTED .. BLOCK FREE FORMAT regards NOOR ALAM
