  1. Inspire not working

    Seems to be related to graphics, if I check the windows logs it is "nvoglv64.DLL" that is the faulting module. Any idea? edit: nvidia graphics drivers* edit 2: Solved it! I re-downloaded an earlier version of the graphics drivers and it worked. Does not seem to be working with the latest drivers as of 2016-08-30. "372.70-notebook-win10-64bit-international-whql" are the ones that did not work. Regards, Markus
  2. Inspire not working

    Hello, After a re-installation of the HyperWorks and solidThinking Student Editions I cannot start up Inspire anymore. All HyperWorks program can start up, as well as Evolve. The version of Inspire is "Inspire 2016 5384 Student Edition". The removal and re-installation is done according to the guidelines given. The license-file is valid until 2017-03-xx, and as all other software can start I do not think that would be the problem? Any help appreciated. I tried doing what is mentioned in this thread, /index.php?/topic/967-inspire-wont-open/ , but that does not seem to work either. Regards, Markus
  3. Problem with model

    Jaideep, Thanks for your answer. I am going to try the thing with removing the hydraulic cylinders and model it with forces instead. I have a question about the excavator crane in the figure you provided. In the connections between the booms, where the joints (pins, I guess?) are. What kind of contact surface are used there? Or is it only the pin? Edit: Or are those connections fasteners? Edit 2: And how do you find what forces to apply instead of modeling the hydraulic cylinders? Regards, Markus
  4. Problem with model

    Hello, I am trying to do an optimization of one of the booms of a simple crane. I have modeled the crane in a CAD environment and imported it to Inspire. In Inspire I set up the model with pins in the connection between booms, and sliding pins for the hydraulic cylinders. The boom where the design space is has been cut and the connecting surfaces are set to be bonded. I also set up supports at the bottom of the crane, and loads at the end of the last boom. See Figure 1. Figure 1. To me, this seems like it should be enough to run analysis and/or optimization. But when I run this model I get an error saying that the model is improperly supported/loaded. What I tried then was to increase the distance used when finding contacts, to set the surfaces where the pins are (the connection between the different booms) to be contacting, see Figure 2. In the CAD environment I intentionally modeled it so they shouldnt be connecting. Using this method I can run the simulation. Figure 2 This leads me to believe that I am missing something and that the results may be weird... Am I misunderstanding something when I try to do it like in the first case (Using no contacting surfaces and only pins/sliding pins)? Why does there have to be contacts, why isnt joints enough? Cant forces propagate through a joint? Do the joints just limit the motion to be relative the common axis of the bodies? Also, when I run an analysis using the second method (using contacting surfaces and pins/sliding pins) I get result showing that the displacements are over 20 meters, see Figure 3, using no gravity and forces of 1000-2000 N. Which again leads me to believe this is not the right way to model this. Figure 3 I'll upload the .stmod file for the model with included supports and loads. The uploaded model is the model with contacting surfaces which gets displacements of over 20+ m. Any help appreciated! Best regards, Markus SimpleCrane_straightConfig_designSpace.stmod
