  1. Hi, Kindly check the following post which could be helpful: Thank you
  2. Hi, Can you elaborate on what exactly the outcome you are expecting. If possible can you share the model file?
  3. Hi, I saw your post: I am working on it and will get back to you asap.
  4. Hi, In dynamic analysis when the geometry is borderline between the classification of 2-D and 3-D geometry, 2-D shell elements are preferred over 3-D. This is because shell elements being less stiffer captures the mode shapes accurately and with a fewer number of nodes and elements. Also, in FEA the result depends on element type and mesh refinement of the model. Thus you are getting variation in stress values.
  5. Hi, You can add the acceleration vs time data in TABLED1 card (it just accepts x and y value which can be disp or acc or other). Create TLOAD1 where you can specify that the data is acceleration. Please find attached: 1. The screenshot which shows the type should be "ACCE" 2. Tutorial: Modal Transient Dynamic Analysis for your reference (note that is does not elaborate analysis using the acceleration data) Thank you OS-T_ 1315 Modal Transient Dynamic Analysis of a Bracket.pdf
  6. Hi, Attached is the link to a pdf which will brief you about 3D meshing. https://www.altairuniversity.com/wp-content/uploads/2012/04/Student_Guide_195-210.pdf Thank you
  7. Hi, There are overlapping surfaces in component LA25 Center Plate which you could split using Shift + F9 and delete the overlapping components and then try to mesh. Note that geometry cleanup should be done before meshing. Thank you
  8. Hi Swapnil, Please recheck if you have assigned material and properties appropriately. If you still don't get the answer, share the .fem or .hm file which you are using for analysis (your solver deck). Thank you
  9. Hi Bhanu, Check the CONTROL CARD in OptiStruct "OUTPUT" where you can control the files you want to be written. Kindly find attached the link from help document for the same: https://altairhyperworks.com/hwhelp/Altair/2019/help/os/topics/solvers/os/output_io_r.htm?zoom_highlightsub=OUTPUT Thank you
  10. Hi Sandeep, Here is the code for your reference: Thank you
  11. Hi Farouk, Could you be more specific about the OptiStruct contacts as there are many contact formulations which OptiStruct supports. Thank you
  12. Hi Kindly refer to the following two posts: 1. https://forum.altair.com/topic/20298-combine-merging-all-components-into-a-single-component-and-applying-constraints/ 2. https://forum.altair.com/topic/2039-merge-components-tcl-command/ Thank you
  13. Hi, You can refer to this post: https://forum.altair.com/topic/18523-how-to-see-stresses-in-the-plies-of-a-laminate/ Thank you.
  14. Hi Karth, By clicking the following image you will be able to display ids: Steps: 1. Click on 2. Click on "loads" 3. Check the "display" button 4. Click on "loads" and select "by collector" By this you should be able to view load collector id. Thank you.
