  1. Hi Joel RBE 2 has infinite stiffness which holds component 2 components tightly Whereas RBE3 doesnt add any stifness used for load and mass transfer. Also rbe 2 can also used for load and mass transfer but rbe2 has stiffnesss component to it
  2. Hi Thanks for your reply I see the formulas are different refer below I want to know for same load given as RLOAD1 AND RLOAD2 cards how will it affect the output Kindly provide me with an example analysis using RLOAD1 & RLOAD2 Refer formulas below Thanks in advance Regards Sai Vignesh V
  3. Hi Kindly help me in understanding the difference between RLOAD1 and RLOAD2? I have seen the mathematical formula differs between both My question is when to use RLOAD1 and when to use RLOAD2? How it will make a difference in the analysis? Also kindly share an example by using RLOAD 1 AND RLOAD2 Thanks in advance
  4. How about post processing steps do you have documentation what will be output and how to process for the same example Thanks for your help in advance
  5. Thanks for the material Regards Sai Vignesh V
  6. Hi I am trying to learn TPA analysis in NVH Kindly someone help with reference deck and document about background process and post processing Thanks in advance Regards Sai Vignesh
  7. I have tried and its not same It would be clear if we could have chat or call to explain clearly what is my issue Let me know
  8. Also let me know if i could contact you through phone I want to sort this out sooner
  9. Hi I checked your model there is no stiffness assigned for CELAS2 and you have created PELAS1 AND THE ELEMENTS HAVE NOT BEEN ASSIGNED STIFNNESS? I have attached my model run the same and let me know what mistake has been made EIGEN2.fem
  10. have a look at this my total mass is 4kg in translation i get my total mass but in rotation i get 250 kg Kindly clarify whats wrong EIGEN2.out
  11. have a look at my model setup and let me know why rotational mass comes wrong
  12. Hi Rahul I am trying to co relate analysis calculation vs theoretical calculation so i took simple 2dof system so it will have oly 2 natural frequencies
  13. Thanks for the answer Rahul Yet still why do i see high mass value in rotation direction Mass value in rotation direction is higher than my system mass kindly clarify
  14. Thanks for reply but in total mass in rotational directions why it is not equal to total mass? in translation i get my total mass equal to system mass but in rotational it shows 250kg which is more than my over all system mass
  15. Kindly find the attached out file In effective modal mass i am getting my total mass in translation direction Why not in rotation of X direction? Is the unit different when it comes to translation and rotation ? Thanks for your help
