  1. Hi rea2 You can use /DT/NODA/CST which add mass on the node when time step drops Refer the e-book (page 261 onwards) for more details regarding time step control https://altairuniversity.com/free-ebooks-2/free-ebook-crash-analysis-with-radioss-a-study-guide/
  2. Hi Try reinstalling the software to a different location. Also change the default working directory as mentioned in the post below
  3. Hi Mario Messaging is disabled for all users. You can post your queries in the forum
  4. Hi Adarsh Kumar The ideal shape for a brick element is a cube. Warp angle is calculated on faces (quadrilateral) of a hex element. It is the angle between the planes that form by splitting the quad element. Ideal value = 0 (Acceptable <30 degrees)
  5. Hi aymanalsukhon You can import .dat file into Hypermesh, but currently Dytran interfacing is not available with HyperMesh. However you can try out the explicit solver Radioss, where you can define Kinematic constrains
  6. Hi QuentinB Is there a specific reason why you are applying pressure? or else you can use this suggestion and try out 1. Select all the nodes of the surface area in contact (white color portion) and make it as rigid. You can use the calculate node and multiple node option inside the rigids panel. Input the mass of the block as force into the master node of the rigid. This will equally divide and apply the force exerted by the block to all the nodes, which will give reasonable result 2. Also the contour image will show the deformation according to the scale factor you have provided. So check the actual deformation values of the deformed region and interpret the result; the deformation may be too low
  7. Hi QuentinB How did you apply the pressure load. Will it resemble a distributed load along the structure?
  8. Hello aymanalsukhon Can you tell us the format of the file to be input. If it is .dat or .nas then we can import
  9. Hello Julio Apart from the e-book "Practical Aspects of Finite Element Simulation" please refer the composite e-book also which specializes on composite modelling https://altairuniversity.com/free-ebook-introduction-to-practical-aspects-of-composites/ Also refer composite tutorials from online help
  10. Hello Tony Qu Please have a look at the example RDE:0400 from Radioss example guide. This may help you
  11. Hi kandiyal There is no particular step in HV like that. You have the option to split window. you can split the window > load 2 different results in 2 windows and compare
  12. Hi Shahzaib Ilyas Yes, Altair does provides e-Learning subscription to students for free. Please have a look at the following learning resources, The HyperWorks Student guides / eBooks - https://altairuniversity.com/free-ebooks-2/ Altair's Academic Learning & Certification Program - https://certification.altairuniversity.com/ The full HyperWorks HTML documentation (part of your installation) provides a thorough, searchable resource to find detailed information about HyperWorks, including an extensive set of tutorials. An extensive collection of interactive training videos (with audio) covering the most essentials about interacting with the graphical user interface, basics of geometry cleanup, introduction in 2D meshing, analysis, debugging, topology optimization, and post processing (visit the learning library https://altairuniversity.com/learning-library/ for more information) Our YouTube channel - https://www.youtube.com/user/HyperWorksUniversity Note that your students can always ask us questions while learning using the Altair Support Forum - https://forum.altairhyperworks.com/
  13. Hello Wiz211 Also try deleting the settings file and try again
  14. Hi mmf Check this pdf from learning and certification program of Altair University. https://certification.altairuniversity.com/pluginfile.php/16403/mod_resource/content/1/Overlaying Images and Videos_Feb.pdf
  15. Hi Laminar_vs_Turbulent Go to preference > graphics> colors and try changing the background colour of the GUI. If that doesn't work, try deleting the settings file and reopen HyperMesh.
  16. Hi Freddie PCOMPP property is used to define ply-based input. It defines the properties of a composite laminate material used in ply-based composite definition Psolid defines the properties of solid elements, referenced by CHEXA, CPENTA, CPYRA and CTETRA Bulk Data Entries Check this attached example and model files 2.1 HoneyCombSandwich.pdf HCSandwich_0000.rad HCSandwich_0001.rad
  17. Hi Skill.Leo0 This is explained in the Radioss reference guide and user guide. Please have a look You can provide Type 7 interface to contact setup between brake pads and brake disk. Refer the attached example also BRAKE2_0000.rad BRAKE2_0001.rad BRAKE2_0002.rad
  18. Hi Sudhanshu Kashyap RBE s are Rigid Body Elements. These are basically used to connect a single node to multiple nodes. RBE2 formulation consists of one independent node and one or more dependent node(s). The dependent node(s) follow the motion of the Independent node in the degrees of Freedom that have been linked. These elements are useful to welds two dissimilar meshes. RBE2 elements induce stiffness to the model. RBODY is also defined by a master node and its associated slave nodes. Mass and inertia can be added to the initial master node location So depending upon your application to have to use Rbody and Rbe2. In your case you can delete those elements and create new RBE2 elements Check Radioss reference guide to know more in detail about RBE2 and Rbody
  19. Hi Check whether you have the HyperWorks solvers installed in your system. Also, try deleting the settings file and try again
  20. Hi Jack Vincent Can you please specify the version of HyperWorks you are using? Is it full version or the student edition
  21. Hi afura You can identify the independent node id of a rigid by using card edit option. click on card edit > select the rigid element and set the options as per image > click edit and then you can see the independent node of rigid. Then for a further selection of this node you can select using node id
  22. Hi Teja Can you try imposed displacement instead of concentrated load. You can measure the distance to which it has to go in and provide the same in the curve for imposed displacement. You can use the properties of plastic as you mentioned above
