  2. Hi everibody! I have the same problem with my simulation. When it starts last iterations i have problem on UPW and after many simulation i really don't know ho to fix it. We tryied first reducing the tollerance on EPSU EPSW and EPSW, then reducing Ksteps (from 5 to 1) and increasing NINC (from 10 to 20). After some attempts i decide to reduce load (although is not properly correct for the fisic model that i'm trying to simulate) from 60000 to 10000. EXPERTNL and CNTSTB are activate. What can i try to fix this issue?
  3. In this pic ishared an example extracted by my model, here you can see where i freeze the surface between shaft and tongue (B) and also where i do the same thing for tongue and wheel (A). The simulation with this configuration converged and i obtain results. howevere preview model gives these results, but in my opinion they are wrong cause they are symmetrical. What i want to obtain is something like this, with asymmetrical stresses congruent with the rotation About the simulation that doesn't converge i tried freezing only few side of the tongue like in the pic that follows Unfortunately the model doesn't converge and i don't know how to fix it I'm going to sent you the model. I state that i have to do a static analysis of the gearbox.
  4. Hi everibody! I'm doing a project for university. I'm trying to analyze a wheels set connected by a tongue but i'm struggling a lot with the facial contact between shaft and tongue and and also tongue and wheel. For first i tried applying "freeze" on every face but it doesn't gives good results so i tried with another configuration but i have convergence's problems. What can i do? I can share the file for more information. Thanks to all!!!!
  5. Yes of course, i share it at the "filetransferlink", the name is "gear motor ERROR 1000".
  6. I've just done verification but all the masters and slaves entities were defined.
  7. Hi guys, i'm new to the program and i'm trying to run my analysis but an error occurs and i don't know how to fix it. I have some Pcont properties in the model and i have already defined NLPARM in load collectors field. However the error still resists. In the space below i attach the error's message Messages for the job: *** See next message about line 9009 from file: D:/Università/PAC/Progetto motoriduttore/simulazione modello completo/mesh definitiva2 "CONTACT 9 4 19 AUTO" *** ERROR # 1000 *** in the input data: Incorrect data in field # 4.
