  1. Hello, I am working on crash analysis of a truck chassis on radioss. In my crash analysis project till day I have been connecting two components using the 1D spotweld panel. I just wanted to know if I am doing it right. I go to the 1D spot weld panel, and I choose the nodes of the edge one component and then I select both components. I use re mesh option and create. I wanted to know if this method is good? One thing I have noticed is that after creating the RBODY, my mesh gets changed and lot of elements fail because of the re mesh option I use. I also get like 1000's of warnings after I run my model on RADIOSS (attached picture). I wanted to know whether the technique I am using is a good practice or is there is any better way for the same. Thank you, Datta
  2. Hi, I have a question on spotweld connectors. I have the following two components with shell mesh. I have a hard time choosing which option to use in spotweld. Pls help me. Please explain which one we should use and when? 1) Mesh Dependent - adjust realization- find nearest nodes 2) Mesh Dependent - adjust realization- project and find nodes 3) Mesh Dependent - adjust realization- ensure projection 4) Mesh Dependent - adjust mesh- remesh 5) Mesh Dependent - adjust mesh- smooth 6) Mesh Dependent - quad transition- imprint 7) Mesh Dependent - quad transition- skip imprint Which method is good and if I use different methods will I get different results? I have used (Mesh Dependent - adjust mesh- remesh) but then I feel that when I do this because of remesh my elements become smaller and fail in quality. Thanks, Datta
  3. I'm trying to incorporate mesh independent 1D spotweld/rigid/beam elements between 2/more BIW panels via contact interface and seem unable to execute. Error: *** ERROR # 2371 *** SET SSID on CONTACT 1 is empty. (1D elements in slave set)
