  1. Hello, I am using 3D tet elements to model a variety of bolted flange plates. I would like to use simplified 1D beam elements as bolts, with RBE2 to connect to each part. Is there a way to use the connector panel to help make this easier? I cannot seem to figure out how to do it for 3D meshes. Also, I have not actually meshed the holes as I am trying to reduce geometric complexity - I have just included a circular "washer" surface for the RBE2 elements to grab on to. My solver is Optistruct. Thank you, Justin
  2. Hello, I am performing a large displacement nonlinear quasi-static analysis of a steel coupon under cyclic loading. I am applying displacement cycles using TLOAD1 and DLOAD, so that I can apply the entire loading protocol in a single subcase (cyclicing between 0.75 mm and 0). I would like to control the loading increment so that I have a smooth force-deformation hysteresis curve, but no matter what I try, the loading increment seems to increase beyond what I specified with NINC in NLPARM. For example, I have specified NINC=1000 (so that the increment should be 0.001), but in total my entire analysis has only about 150 increments. I have EXPERTNL turned off, and if I also turn off LGDISP, everything works fine, but once I turn LGDISP on, the increment seems to be automatically determined. Please advise! See attached for my model. Thank you, Justin Coupon4B_largedef.hm
