  1. Hi Find below the Radioss Full car model. This is a public model. Regards Prashanth A.R TAURUS_A00_0001.zip
  2. Hello Suraj, Good to know this. To capture the spring back effect, you have to run a implicit run followed with the rolling analysis. So you have to have a second engine file in which you should have these springback options. I have attached a sample file here, you can use the same file by changing the file name. As this is a second engine file, file name name should end as _0002.rad. You can restart your run to see the springback effect. In this forum, I have explained the procedure to restart. Please go through Regards Prashanth A.R Run_0002.rad
  3. Hi Procedure to Restart First, while submitting the files for restart, please create a new engine file (may be copy - paste original file) and edit the extension from *_0001.rad to *_0002.rad Next, in the newly created Engine file, you have to edit the number in /RUN, ex. /RUN/Drop_test/1/ will become /RUN/Drop_test/2/ Finally, while submitting the run call new Engine file(*_0002.rad) which you have created use same number of cores what you have used for the first run. Note: During restart you can also change many parameters (If needed) in the engine file like Termination time, Animation Frequency, Time History Frequency, Apply BCs, Apply Loads, Delete Interface/Part/Element etc Regards Prashanth A.R

  5. Dear Suraj, Download the model from below link. Loads and BCs should be only on the Master node of RBODY. Don't use StFac in the Contact for this case You are running the model with a high time step which I have reduced. https://ftin.india.altair.com:8443/message/AsTEsVuIsQRyb7aPyfI0Gu Regards Prashanth A.R
  6. Hello Suraj, From the out file I can make out that you have 99% error in the contact from the beginning itself. The suggested parameters for TYPE7 contact are: Istf=4 Igap=2 Fscale_Gap=0.8 INACTI=6 Gap_min=0.1 Fric = 0.1 Iform=2 Make sure you have these parameters Regards Prashanth A.R
  7. To understand, how to build Radioss model using HyperMesh you can refer these Video Series. Watch it in YouTube to get access to entire list of Chapters.
  8. Hello Suraj, It will be good if you send the _0001.out to understand the issue. From these lines, it looks issue is coming from Interface Id = 1. What are the parameters you are using for this contact. Regards Prashanth A.R
  9. Now you can download the PDF format of Radioss Reference Guide, User Guide and Tutorial from this Forum. RADIOSS_2017_Reference_Guide.pdf RADIOSS_2017_Tutorials_and_Examples.pdf RADIOSS_2017_User_Guide.pdf
