  1. Hello, Just a quick question: I want to combine an average load and an amplitude load for a fatigue analysis. Should I combine the two within the FATEVNT load collector (I think it is the right one) or should I combine the two within FATSEQ (I think it is more for repetition of loads) ? Could you help me with that ? Also a side question: Is there a way to see the displacement results within Hyperview on an iso-density view of my piece in order to view the displacements on the result of my topology optimization ? Thank you in advance for your help. Regards, Adrien
  2. Hi, Just to note that I am also interested in this answer. So if somebody has an intel, i am all ears ! Adrien
  3. Hello Prakash, How can I do that ? Is it an option available within hypermesh or should I download this version (And where to download it) ? Thanks again for your help. PS: My technique seems to work so it is mainly to compare the results. Adrien
  4. Hello, So this bug is reported, where can I look how to overcome it ? Thanks in advance. Regards, Adrien
  5. Hello, I am trying to do a topology optimization over a subframe piece. In order to do that, I minimize the volume with respect to all the load cases. As of right now, I am trying to add a natural frequency constraint to my problem. To do that I followed the tutorial: OS-2020: Increasing Natural Frequencies of an Automotive Splash Shield with Ribs However, by strictly applying that tutorial, I encounter the following error: *** ERROR # 5617 *** The SUBCASE ID in ATT1 field of DRESP1 1 does not refer to a modal FRF subcase. From what I understand from it, it is due to the loadstep defined during the creation of the response (Not appearing in the tutorial, maybe due to an update?). By suppressing the link to a loadstep by editing the response, the optimizer runs fine. However, I am not sure it took my constraint well into account. Thanks in advance for your help. Regards, Adrien
