  1. Hi Teja I will update you today
  2. Hi yogeshchandra Check this C
  3. Hi yogeshchandra As per the file you send, I can see that the material was not specified. Please update the material in the /FAIL/XFEM/JOHNS property card and try running the analysis. It is working fine from my end
  4. Hi Amasker Can you please explain for which functionality you need to duplicate element
  5. Hi Chungeon Kim Is it possible to convert the APDL file to cdb file? Then you can open it in Hypermesh by switching the user profile to Ansys. You can use import solver deck option
  6. Hi yogeshchandra You can output Stress and strain using output blocks. Go to Analaysis page>> Output Block>> elements. Card edit the created output block and change the keyword accordingly (BRIC for solid elemnts, SHEL for shell elements, etc..) Select the variables and please go through /TH for more information about variables. All the requested information will be written to T01 file. The other way is plot stress and plastic strain from HyperView. Output Stress and strain through control cards and contour stress. Go to Plot curves and plot Stress Vs time. Similarly do the same for strain in the same existing window and do a cross plot in HyperGraph. 
  7. Hi aymanalsukhon Check these forum posts on similar topics Also, check Radioss online help documentation for more details regarding Radioss parallelization
  8. Hi durukanbdilek I recommend you to update the version
  9. Hi Which version of Hypermesh are you using? Check this doc about the recommended GPU's. HyperWorks_2017_Hardware_Recommendations_and_Certifications.pdf
  10. Which version of Hypermesh are you using?
  11. Hi bhanutheja It is possible by using /ACTIV card. It describes the deactivation/activation of element groups Check Radioss reference guide for more details. In 2019 HM iform option was added to /ACTIV card where you can activate and deactivate the elements.
  12. Hi durukanbdilek you can see 2 Rbodies created in the edited file. The above-shared video explains the creation of Rigid body using Radioss user profile. Since you are using OptiStruct user profile, you need to create likewise. Also, refer online help for more details regarding shell thickness offset
  13. Hi durukanbdilek You can right click on Model Browser>> Create>> Rigid body. Make sure you go through the Rbody card on OptiStruct help before you create as it gives a fair idea on what is required for Rbody. The file has been edited and attached. Also, an example file is attached which you can use as a reference Since you have already given node to node connectivity between the honey comp material and plate, a need for an additional contact is not there 3Point_Bending_RBODY.fem rbody.fem
  14. Hi durukanbdilek Can you please explain more about your requirement with some images or so
  15. Hi Temitope I think this is due to some graphical issues. Can you please provide more information about your system specification including your GPU details
  16. Hi Pritish Shubham ERR signifies the Energy error percentage It doesn't mean the deviation from the result. Negative Energy Error represents energy dissipated from the system and this can be from many sources including plastic deformation and Hourglass energy. Please check the hourglass energy of the model.Keep Isolid=24 and try running the simulation. If the components penetrate each other due to the loads applied the user need to define an interface/contact between them for achieving a realistic simulation. The master segment can be parts, elements, contact surface, node sets and similarly for slave the selection can be parts and node sets. Once these master slave sets are identified the algorithm will check these locations for potential penetration of a slave node through a master segment, and this check is done in every time step Negative Energy Error represents energy dissipated from the system and positive energy error means energy absorbed in the system 4. What should be the ideal scenario of ERR Values we should expect while running a solution? You should check hourglass energy and contact energy in your model. ideally (Hour glass energy + contact energy)/Total energy < 15% Also, check the Radioss explicit e-book( https://altairuniversity.com/free-ebooks-2/free-ebook-crash-analysis-with-radioss-a-study-guide/) Page 283 onwards Check this forum post also
  17. Hi Check whether any one of these connectors suits your requirement. Also, check online help for more details regarding each connectors https://altairuniversity.com/wp-content/uploads/2012/04/HM_1D_Extract.pdf
  18. Hi durukanbdilek Similarly, you can switch on calculate node and multiple node option and select all the nodes of the plate which you want to make as a rigid. The master node will be automatically calculated. Hope it is clear
  19. Hi JM Desrosiers While importing it back to Hypermesh, uncheck the solver option as shown in the image below. It will be in the separate components then.
  20. Hi JJJ Manually you can do by using Rigids (RBE2) or connectors. Check this pdf for more details on connectors https://altairuniversity.com/wp-content/uploads/2012/04/HM_1D_Extract.pdf
  21. Hi Teja This seems fine. You can use Mat law 2 also for plastic component
  22. Hi William_Taylor You can find more information inside the learning and certification program of Altair university https://certification.altairuniversity.com/?lang=de
  23. Hi Teja I am working on your model. You can also try these suggestions from your end 1. Increase the value of concentrated load so that the plastic component is pushed in 2. Type 3 seems ok for defining the interface between teeth and steel part (hole inner face). Provide a type 7 interface between the bottom face of the plastic component and the steel part so that it doesn't intersect through the steel plate
  24. Hi Satyaswaroop These documents will give you an idea about the approach https://www.altairatc.com/india/previous-events/atc/2015/technical-presentations/OS-02-Optimization_of_the_Body-In-White_(BIW)_for_Multi_Maruti.pdf https://pdfs.semanticscholar.org/929f/0cbbc0b5387cab50270b91d85fec0968ef8b.pdf
  25. Hi Stefano It depends on the component. Normally we extract mid surface or do mid mesh and assign thickness Go through the chapter "meshing" from the e-book "Practical aspects of finite element simulation" (https://altairuniversity.com/free-ebooks-2/free-ebook-practical-aspects-of-finite-element-simulation-a-study-guide/) Also, refer to online videos and tutorials available for the same
