  1. Shell element dragged

    Hi George, I have modelled using spotwelds only where I choose element type as RBODY.
  2. Shell element dragged

    Hi all, I am performing an Impact analysis and I have few components which I have connected using 1D element as shown in the picture. However after the analysis these connections look very different . The elements have got dragged. Can someone tell me what is wrong?? Thanks, Datta
  3. Pressure

    Hi, If after I create a Pressure load using surfaces option I have gone to loads on geometry and mapped the loads. My question is after this do we have to delete the loads that we created on the surface? Thanks, Datta
  4. Load transfer in RIGID Element

    Thank you George. So can we conclude that in Radioss RBE2 and RBODY have the same effect?
  5. Load transfer in RIGID Element

    Thank you for the reply George, So when you say transfer of load is possible what do you mean? Does it work like similar to RBE2? Suppose I apply 100N load on the green component in the picture, will 100N be transferred to the blue? Thanks, Datta
  6. Warnings

    Hi, I am getting these warnings, Can someone please tell me what may be wrong and how to correct it. 1) WARNING ID : 183 ** WARNING IN HIERARCHY (PART TO SUBSET ID) DESCRIPTION : -- PART ID : 1 -- PART TITLE : rubberpad REFERS TO UNEXISTING SUBSET ID=75 2) WARNING ID : 692 ** WARNING IN SURFACE DEFINITION DESCRIPTION : THE SURFACE ID=5508 IS EMPTY Thanks, Datta
  7. Load transfer in RIGID Element

    Hi all, If I connect two components by the RIGID panel using the RBODY element. I wanted to know how the load transfer takes place. Suppose I apply load to one component will the entire load be transferred to the other component? Thanks, Datta
  8. Contact

    Hi George, Thank you for answering. I wanted to know how the load transfer works in the case of Type 2 and Type 7 interface. I could not find in the manual. In both the interfaces does the load transfer takes place from the slave surface to the master surface or the other way ? Thanks, Datta
  9. Contact

    Hi, I am trying to simulate contact for performing frontal crash analysis of a chassis having a tank. I have a tank which is wrapped by two brackets and supported by rubber. This bracket is welded to a chassis. I need to create contact for the following- 1) Between tank and bracket. 2) Between rubber and bracket. 3) Between rubber and tank. It is attached to chassis as follows- I know that I need to create Interface. Please tell me for each case which Type interface should be used and which should be selected as master and slave? Thank you, Datta
  10. RIGIDS

    If I want to connect two components can I use components to select in the rigid panel? Thanks, Datta
  11. Increase in Error

    Ok will check that, Thank you George.
  12. Spotweld

    Thank you George and Rahul for the reply. I went through the Tutorial and the ebook, but I could not find an answer for the same. I want to know which one to use, because I am really stuck at this. Please help me!
  13. Increase in Error

    Thank you George and gopal_rathore for the reply. In my Energy plot total energy is increasing, which should not happen. I am attaching the out files can you please check and tell me what is possibly wrong?? geometryfiletomeshinmm_hm_crash_10mm.criteria_crash_10mm.param_0000.out geometryfiletomeshinmm_hm_crash_10mm.criteria_crash_10mm.param_0001.out geometryfiletomeshinmm_hm_crash_10mm.criteria_crash_10mm.param_0000.rad
  14. Increase in Error

    Hi, In my model Error is continuously increasing, can you please tell what may be possibly wrong?? Thanks, Datta
  15. Unmeshed Surface

    Hi, I used batch mesher to mesh a huge model having various components. In the generated quality report, it said there are three unmeshed surfaces. Is there any way to know which are these surfaces in the meshed model? Thanks, Datta
