  6. HeIlo, is there any way to create short cut or tcl file to select elemnts by adjacent by clicking on a single element? Please help me.
  7. Dear sir, I want to analyse a model in radioss implicit which was ran in abaqus for vertical loading (non linear static problem with contacts), what are the basic implicit cards i should use to perfrom non linear implicit analysis (with vertical loading of a plate on roof structure and type 7 contacts , elastic - plastic material also) in radioss and compare the results with abaqus. Is there any tutorial which have executed the run in radioss using implicit cards. Thank you.
  8. No, issue i have got the solution, thank you.
  9. Dear sir, I am doing Head Impact on ip and plotted the acceleration curves in hyper graph.

  14. Internal Energy Higher Than K.E

    Dear Sir, Thanks for the help, i have run the analysis with n=5 and ishell 24 formulation in radioss but the problem couldn't be resolved 1)still the internal energy is high from the start of the run . 2) after 14 iterations its saying time step error is equal to zero, though the mass error is 1.3e-1 at that time and energy error is -8.1 which are acceptable limits. Attached are the pics and out files and please help me with this. Thank You. Ip_solid_n5_0000.out Ip_solid_n5_0001.out
