    Applying torsional moment to shell/support in PVElite

    Hi All, Thanks for your replies. @jt1234 Thanks for reminding me that. Agree that torsion generally results in less stress. @CuMo Thanks, this is very helpful. I turns out that I am using an older version of PVElite which doesn't have this option. I need to upgrade to the latest version...

    Applying torsional moment to shell/support in PVElite

    Hi, I have a vertical vessel which has tangential nozzles. These nozzles are subjected to thrust load due to process reasons. This results in a torsional moment on the whole section of the vessel that also affects the support (skirt & base ring) of the vessel. I tried adding moment to the...

    Ansys Workbench/Mechanical Memory Options

    Hi, I have a pretty good pc at work with 28gigs of memory and the processor is Xeon 2 core 3+ hertz. But even a small model takes ages to solve. I notice that my colleague who is running Ansys on a lower spec machine, and when he is running similar models it doesn't take a lot of time. Am I...

    Primary bending stress

    See attached. This is from book by Denis R. Mosshttp://files.engineering.com/getfile.aspx?folder=f0ea9f40-0be0-47fc-bf72-bfe8180e74c6&file=Primary_Bending_Stress.png

    Re-rating of U-Tube exchanger

    Thanks for your reply metengr. What would be the "local regulatory body" in this case? I thought NB is the locale regulatory authority in US?

    Re-rating of U-Tube exchanger

    A brand new exchanger (U-Stamped + National board registration) was not stored properly and tubes are corroded internally (30% max). Now as per calcs, still there is enough thickness. What I don't understand/know is that how shall we proceed with the documentation? 1- Do a rerating calcs and get...

    Pipe Clamp, how to apply supports

    Rick, That's a very good point. I will try to model it without contact. Thanks.

    Pipe Clamp, how to apply supports

    WellI end-up modelling pipe as well, Which gave me a very good result. In fact I also modelled the base structure as well. Thanks sk_cheah Well I do expect the front edge to move a little bit towards positive y due the moment about z-axis. So I ended up modelling the pipe as well. See...

    Pipe Clamp, how to apply supports

    rickfischer51, Thanks for your reply, I really appreciate that. I understand what you are trying to say. However that will limit the inside bore of the top block both in +x and -x directions (I suppose, correct me if I am wrong). However I just want to restrict it towards the pipe (-x axis of...

    Pipe Clamp, how to apply supports

    Hi, Its my first post here. I hope it goes well. I am designing a pipe clamp. I have not modelled the pipe itself, as I need to apply moment and forces on the face resting on the pipe (bore of top block). However I am struggling to constrain the top block. Right now I have put a cylindrical...
