I modified the user subroutine
mdeos_user_1.f90
, wrote a custom ideal state equation, and injected energy through a custom energy deposition subroutineSUBROUTINE EXSIE3 (DSIE)

This is really useful.nBest,nKarthiknDecember 10, 2020 at 6:13 pmChris QuanAnsys EmployeeHi Limandinuo, temperature is calculated from internal energy and specific heat. Make sure the specific heat is not zero and has a reasonable value in your user EOS subroutine. nDecember 14, 2020 at 9:48 amlimandinuoSubscriberHi Limandinuo, temperature is calculated from internal energy and specific heat.

nThank you very much for your answer!!!!!!! This probelom has bothered me for a long time.ArrayI think you are right ,i should not modify the temperature directly in mdstr_user_1.f90nnBut the specific heat I set in the mdeos_user_1.f90 (equation of state) does not seem to work . So I asked a new question about thatArray . Would you please help me to answer it ? Hope it won't disturb youn the question about specific heat :/forum/discussion/22860/autodyn-user-subroutine-the-specific-heat-capacity-set-in-the-modes-user-1-f90-does-not-work/p1?new=1nDecember 15, 2020 at 4:25 pmChris QuanAnsys EmployeeI posted my answer under your another postnViewing 5 reply threads- The topic ‘I used user equation of state subroutine, why does the temperature of the material not change?’ is closed to new replies.
