  1. Hello everbody, could someboby help me? I want to analyze the hertzian pressure between a ball and plate. But there are some mistake (pictures below). Thanks!!
  2. Short Version I am quite new to FEA and HyperWorks and am modelling a suspension bridge with a distributed load and a ball-joint to connect the vertically running cables to the main cables and deck, but with a Linear Static load step the joints are ignored. Slightly-longer version The bridge I am modelling is the Humber Suspension Bridge found near Kingston upon Hill, England. The model has a distributed force across the top nodes and I have attempted to connect a few vertically running cables to the deck using a ball joint from the Mesh > Create > 1D Elements > Joints menu. The deck and support have been imported from CATIA and then (2D) meshed whilst the cables have been created using lines then line-meshed with a Beam Section. When I attempt to run the analysis with a Linear Static load step the Solver View states the joints are ignored and "MBD cards are present in the data, but there is no MBD sub cases. JOINTs, MBD loads and other MBD cards will be ignored". So I attempt to use a Multi-Body Dynamics load step but I'm not entirely sure what to put in the variables other than my constraints in the SPC. My forces are currently of load type FORCE, should they be MBFRC? Kind Regards
