  • Hi, I'm not sure I understand what your goal is beyond importing the STL data. Are you assessing the production tooling or the manufactured components? or both? 1) If it is the manufactured component... what are you going to do with the 3D scan da…

  • Hi, looking at the spec for Artec Studio v14 it can export geometry as OBJ, PLY, WRL, STL, BTX, PTX, AOP, ASC, Disney PTEX, E57, XYZRGB. Looking at the Mecway import options it can read STL files - see section 13.4 of the manual https://mecway.com/…

  • One other complication that just crossed my mind is that the plate will sag before it is bolted down, so its initial shape isn't flat before it is bolted down and the 145kN mid load is applied. This might be beneficial, but is more complicated to re…

  • Hi Lemar, Victor is right about the total forces balancing, but the caveat on this is that the distribution of forces between your constraints isn't necessarily accurate. For example, if the point load causes artifically high displacement at that n…

  • When you say "shear forces from the moment developed" what do you mean? Do you mean shear force developed at the edge pins from the plate bending and trying to pull its edges inward? If so, then you need to enable non-linear geometry otherwise there…

  • I also would love the ability to toggle on/off multiple DOF constraints in a single window. Thanks, Pete.
    in Nodal supports 6 DOF Comment by badbunny September 2019
  • Hi Victor, I tried this and it works (mostly). Some caveats though... I had a 2nd order mesh so needed to convert to linear elements first before the extrude, then convert back to 2nd order again at the end. This loses the real midside node positio…
    in Axisymmetric element edge selection Comment by badbunny July 2019
  • Hi Victor, I found the paint select the quickest way in the end as the curved shapes make the rectangle tool less quick and more prone to picking up the element faces. I did use the rectangle tool on the straight sides of the vessel though. Can I …

  • Just a few thoughts, some of which I'm sure you've already had... 1) There is a hydrostatic pressure loading for the product fill dead gravity load (assuming the product can 'flow' to fill out the tank), but in addition to this there will be a dynam…
    in Best practice for modeling thin wall square vessels Comment by badbunny June 2019
  • Hi, I tried running this analysis the main issue I ran into is that the beam is not constrained against free body rotation around the y axis. Like Victor said, If you add a x displacement constraint to one of the nodes lying on the base rigid end in…
