  1. Hi, I am simulating the crash box, however, the simualtion stops after a certain point automatically (after 5 Animation files) Also, there is no 0001.rad file being generated. Please help!
  2. Hi, Yes, the simulation takes a bit of time to run..but unfortunately, including all the nodes to initial velocity is also not working in this case. I am quite confused as to what the problem with this model is.
  3. Hi! I have changed the mesh and also fixed the base plate. I cannot change the size of the impactor because this is the same we are going to experiment with. However, even now the same problem persists. I have also tried with the imposed displacement for my new model and it also does not run properly. Where am I going wrong? Please help!
  4. Hello! I am trying to do a crash simulation and I have meshed all the parts. However, when I open the radioss file in HyperCrash, it shows me intersections. I have tried using Type 7 and Type 24 contact with all the required parameters and stilll facing the same issue. I need all the parts to be connected to each other. What can I do?
  5. Hi, I have increased the mass of the impactor and yet the crash box is not deforming as expected. Also, the Energy error % seems to be within acceptable limits. What can be the issue then?
  6. Hello! I am trying to simulate a crash box and I am also getting results. But the Simulation Shows no movement and Deformation of the crash box. Also, the error % varies between 0 and -8%. What can I do to get the Deformation of the crash box? Also, how to reduce the error %? I have checked my material and property values as well. Thank You!
  7. Thank You! This one really helped to get results.
  8. Unfortunately, even having different iterations of TFREQ and TSTOP is not working. I am getting the same values for time step and only one Animation file.
  9. Hi, Thank You for your Reply. I have already defined ANIM/DT with TSTART=0 and TFREQ=1. Still not able to get Animation files.
  10. Hello! I am currenlt using Hypermesh to simulate a crash box. My model has Zero intersections and penetrations and the model check also Shows Zero Errors. During Simulation, the error keeps on fluctuating negatively between 0 and -2% and the dm/m value is also very low but constant=3.4636e-02 In the Simulation file, only one Animation file is being created i.e. A001. How can I Change the model to obtain the further Animation files? Thank You!
  11. Hello, I am currently using Hypercrash to simulate a crash box model. I am getting Zero intersections and penetrations and the model check also Shows Zero Errors. During Simulation, only one Animation file is being generated i.e. A001. Also, the error keeps increasing in negative and the dm/m Ratio is also very low but constant. What can be done to get the further Animation files like A002,03,etc? Thank You!
