    contact

    Hello, I want to simulate a rivet Joint just applied shear force. Between the rivet and the hole in the metal Sheets is a gap. I get convergence but the rivet turns a Little. u can see it if u watch the displacement Contour plot on the rivet which is not symmetric. Is that because of the coarse mesh? I tried to use gap elements but maybe i put some wrong Setting. attachted are the model. Can anybody help me to fix the Problem? rivet_joint.zip

    creating gap element

    Hi, Does anyone know how to create gap elements around a cylinder which is inserted into another part? Thank you, Soraya
  3. Submitted by Joe on Tue, 05/11/2010 - 18:22 I am modelling one boiler. The burner will be working at duty or standby mode. However, due to the boiler's design limit, once the boiler goes into standby mode, it can not switch to duty mode within 10 minutes. I wonder how I can add this 10 minutes gap in the model?

    Initial Contact

    Hi there, Is it possible to define an initial contact between to surfaces in HyperCrash, while running RADIOSS, so that there isn't neither a gap nor an initial penetration? Thanks

    Mesh Refinement

    Hi there, I m performing a 3-point bending analysis on a beam (L=250mm, Squared Cross-section 30*30) and once I refine my mesh to a certain degree (elements' characteristic length < 0.5mm) I start getting error messages sent by RADIOSS. The first tells me I have initial penetration on my self-impact interface and the second is message error id 22: ShellID ... has 2 identical nodes that are not 3&4. Any idea on how to solve these issues? I ve already tried to decrease the minimum gap for initial impact, but it didn't work. Any help would be great Thanks

    Autoprocess- Binder Gap

    Sir, When we use the Autoprocess forming setups, for binder row, how is the use of the column 'Type'? When I toggle the option to 'Gap', the three columns as highlighted in the attached picture are available. Please elaborate how to fill those cells.

    GAP with model 3D

    Hello, Could you give me one method to create element gap between the axis and the lug ? I use Optistruct with nonlinear gap analysis. The nodes of the lug and the axis have the same coordinate. Mesh with CPENTA and CHEXA. Thanks for help. Benoit

    Problem with INTER/TYPE7 Gap-Offset

    Hello All, i have some trouble modelling contact of a tooling-part an a sheet-part (see first pic) The red arrows in this picture show penetration of the same value as the GAP_MIN value in my inter/type7 card. It is not an effect of bad meshing, but has to do with how the offset for the conatct gap is generated on free shell edges. Which is that the GAP_MIN value is offset circular around the edge. My Question: is there a way to reduce the gap offset like in the second picture?
