  1. Hi everyone, I need an urgent help from all of you. I am doing a viscoelastic material simulation in radioss using kelvin maxwell law. i have the material data in storage modulus vs frequency so i changed my data into g(t) vs t. now when i go for curve fitting the value of prony term gi is coming greater than one.. As i have read in abaqus manual that value of gi should be less than 1 ,, so my question is this theory applied with radioss also or I can use my prony term coefficient which are coming greater than one.Please clear my concepts regarding this or also as per radios can i take the no of prny term more than 5 during curve fitting,, clear my concpts regarding this
  2. Hello, I'm wondering if I can generate a .sta file like in a stamping simulation with an Engine Keyword in RADIOSS 0001 card? Anyone know if it's possible? Thanks in advance!
  3. I am looking to perform airbag simulations involving the inflation and shock attenuation of the airbag. I have seen that RADIOSS has been used for this but can't find any guides to get me going. Is there anyone who has had experience modelling airbags using RADIOSS that could offer me some advice or point me in the right direction?
  4. in preferences --->user profiles --> hypermesh ---> radioss ---> bulkdata there are many options like bulkdata/block110/90/100 . what does each of them signify and when do we use each ? see attached picture for reference. thanks
  5. Can anyone help me with modal analysis of bottle filled with 20% water in it.
  6. Dear all I post for the first time. I'm Takky, Yokohama National University in Japan. Could you please tell me how to output the load force of side members and the barrier surface in contact analysis? I need its graph. I can't output the load force data of the barrier nor side member. I once used the output block on each RBODY of the barrier surface and side member, but no data was output. On HyperGraph, only "Global Valuables" is available, but no other data in "T01-file". In this analysis, the bumper model crash into the rigid offset barrier surface in front, in initial velocity of 50km/h(13.9mm/s). The analysis sample on this image, I wanted to output the each load force of right and left member, but couldn't. In another analysis, I made one rigid body from two members and tried as equal, but couldn't. So, it's not because there are two rigid bodies in rear of bumper, I think. I sent its HM data together. Any ideas?? bumperA_inivel_2.zip
  7. Hi All I'm a new user to Hyperworks and I am coming up against an error #13: Element # is repeated in the input data. I've tried renumbering my elements in the mesh but still the same error appears however the element number changes. Any ideas on how to progress? Cheers
