  1. I have the same problem. Is not possible to know how the algorithm works in GRSM method? There are a lot of different algorithms, for instance: Line-Search Approach Trust Region Approach Simplex Method Newton’s Method Quasi-Newton Methods Conjugate Direction Methods Levenberg–Marquardt Methods Elimination Methods Lagrangian Methods Active Set Methods Penalty and Barrier Function Methods Sequential Quadratic Programming Mixed Integer Programming NLPQLP Many Thanks
  2. ok, let's suppose for instance that my changes were about thickness on the front rails for my vehicle. Thickness varies within few millimiters (about 3mm), but when It's thin, the car folds deeply against the wall, whereas if It's thick, the car folds a little and then has a rebound. With the cut approach I have imposed the displacement to the section force so that the car's dynamic is fixed, isn't it? In this way, I cant't appreciate differences due to the thickness changes, can I? (Total mass isn't very affected from thickness changes (less than 1%), but stiffness might be) Many thanks again for your reply
  3. Hi, I have an issue with cut approach (https://altairuniversity.com/learning-library/radioss-sub-modeling-cut-approach/). I'm modeling an half of full vehicle with the cut approach above. From this sub-model, with hyperstudy I modify a little bit the geometry and study how the crash changes dynamic. I wonder how dynamics could vary among runs if the section-force imposes original displacements? Many Thanks
  4. Thank you so much, Andy. Thorough response!
  5. Good morning, I have an issue when I run a RADIOSS .rad file on my local group's cluster. At the end of the analysis, It doesn't automatically extract the .h3d file, although It does so locally on my pc. I have all animations A0*, but I'd rather It extracts h3d automatically instead of doing manually with hvtrans. I use Radioss Block 120, Many Thanks
  6. ok sorry, just solved. From Preferences>keyboard settings just fill a free gap with "hm_pushpanel {qualityindex}".
  7. Hi everyone, I wonder whether it's possible to configurate as a shortcut the 2D--> quality index. I know that from Preferences>keyboard settings I can change shortcuts, but i need the scripts and I can't find that one in my folders. I use Hypermesh 2019.1, many thanks! Regards
  8. This solved my issue. Many thanks! Was there a bug in previous versions?
  9. It's a little tricky for me, but i could try as soon as possible if there aren't any other solutions. I will keep you informed
  10. No, I'm using full version 2017.2 of hyperstudy and I've indicated Radioss.bat (2017.1) as script, but also with the same version 2017.1 (of Hyperstudy and Radioss) I encountered this problem
  11. Hi, I'm using Hyperstudy 2017.2 and Radioss as a solver. I encounter an error when I perform the evaluate step in the DOE approach. It happens that during a run (whatever) the evaluate and extract steps can't finish succesfully, but there aren't errors in the messages box and in the .out file I can read that analysis is already finished with normal termination: in spite of this, the cursor keeps turning and seems to be waiting to finish evaluation. I realized that when it happens, there isn't the .h3d file in the run folder, even if run is completed and all animation A0# are created. I realized also that by finishing the "hvtrans" process from the task manager, or (is the same) Tclsh85t application, hyperstudy concludes the evaluate step, extracts results and goes to the next run. It's a random problem, but it always happens at least once. Thank you all for helping out.
