  1. HIGH CONTACT ENERGY FOR SINGLE SURFACE CONTACT

    Thank you sir, cleared the problem and its working fine.
  2. HIGH CONTACT ENERGY FOR SINGLE SURFACE CONTACT

    thank you sir, i am using single surface contact, what should be the physical gap value, as i used 0.001 for self contact and there are no penetrations for single surface contact type 7 and i used the same parameters prescribed by you and still the graph looks same.
  3. DEar sir, i was perfomimg impavt analysis using single surface contact and the problem i have been facing is the contact energy is very high from the start of the run as shown in pics below, later i used the parameters u have suggested in forum, it have been decreased but very slightly, i want to reduce it to below 10% and also i want to know why its happening like that. please check the images for further clarifications. SEcond one is having high ontact energy even though i have followed the parameters you have suggested in forums that is for self contact gapmin= 0.001. PLese hlep me to solve this. Thank you
