Hi Abaqus users,
I want to write a user defined subroutine for gap electrical conductance (GAPELECTR) based on maximum temperature history of the nodes at the contact surface. However, I don't know how to calculate maximum temperature of the nodes of the contacting interface at each time step using user subroutine and use that max temperature values in GAPELECTR. Is it possible to give a guideline how I can solve this problem? Any suggestions will be highly appreciated. I have copied the sample code for GAPELECTR from Abaqus and pasted below:

      SUBROUTINE GAPELECTR(SIGMA,D,TEMP,PREDEF,TIME,CINAME,
     1 SLNAME,MSNAME,COORDS,NODE,NPRED,KSTEP,KINC)
C
      INCLUDE 'ABA_PARAM.INC'
C
      CHARACTER*80 CINAME,SLNAME,MSNAME
C
      DIMENSION SIGMA(3),TEMP(2),PREDEF(2,*),TIME(2),COORDS(2,3)

      user coding to define SIGMA(1) -- SIGMA(3)

      RETURN
      END
