  1. Hello Prakash, Thanks for the reply. The problem is type linear static. I referred to other threads where the local CSYS was defined in HyperView as well. But the displacement results resolved in CSYS created in HV still show non zero displacement at new CSYS. Regards, Ashish
  2. Hi Prakash, CSYS was created using the following: Menu > Mesh > Assign > Create by Axis Direction --> Selected origin node --> X-axis defining node, and finally XY plane defining node. Rectangular coordinate system was used. I am unable to share the model. Regards, Ashish
  3. Hello, I need help regarding assigning local co-ordinate system. I placed a local co-ordinate system at one node, which is at certain orientation w.r.t. Global CSYS. After analysis, I observe positive displacement on the node where local CSYS is applied. Is it the expected behavior? I expected the newly defined CSYS (or the origin node) to remain stationary when results are resolved in new CSYS. Please suggest if I need to do something different. Refer to attached image of crack tip and local CSYS defined (small dot shown in grey colour, a little downwards of crack) Regards, Ashish
  4. Hello Mario. i have question similar to bilgilid, but i think more basic. Please excuse if question sounds too trivial. I placed a new local CSYS at one node in HV, and am trying to plot displacement resolved in new CSYS. But, I expected displacement at new CSYS to be zero, while HV gives positive values. Am I missing something in the definition of CSYS? My requirement is to make particular node and plane as basis of calculation for other nodes (solving a fracture mechanics problem, and need to shift CSYS to crack tip for further analysis) Thanks, Ashish
  5. Hello Prakash! The simulation shown in video link is for modal analysis, while I am trying to get strain energy for linear static analysis. Further, the "operator" tab in expression builder shown in the video link has Model as a drop down option, which I do not get in the analysis run I do for linear static. Is there some control card that needs to be applied to get such operator? Thanks, Ashish
  6. Prakash, I need to sum up the element strain energies to obtain one value for total part. Please refer the following link: http://www.altairhyperworks.com/training/new_feature_videos/11/videos/result_math_PartTotalStrainEnergy_final/result_math_PartTotalStrainEnergy_final.htm In the video in above link, individual parts are isolated based on total strain energy, in place of element strain energy. That allows for part identification based on particular values (again, total strain energy). I require Total strain energy as that needs to be filled in another equation for subsequent calculation.. Ashish
  7. Hello Prakash Thanks for the reply! I got contour of strain energy for individual elements as per above method. What I need is the total strain energy for a part, with or without the contour for individual elements. Please see the attached image for elemental contour plot I got. In place of individial element, I require total part strain energy. The analysis has one part only. Thanks Ashish
  8. Is it possible to compute part total strain energy for linear static sub case? I can get element strain energy, but am unable to compute strain energy for whole part. - Ashish
  9. Hi friends. I am a new entrant into HW suite, and have started with Optistruct for learning to use HW products. As a beginner exercise, I have tried to go with tutorials provided on HW website. In the first tutorial, regarding optimization of Housing assembly, I am facing the following issue: In the DESVAR option, as shown in tutorial, the option to be selected in ELEMS, while in my case, only PROPS (which i guess is defining the element solid properties, used is MAT1). I have followed all steps as shown in tutorial. Is there some issue with the element building? or if any other setting is to be used? I am using Optistruct (as required in tutorial) in the Preference menu. Please help Regards
