Subroutine readEG is the subroutine belong to the strain-stress solver, which is activated by the command $uselocalelement. This subroutine is called after the strain-stress solver read in the input file and allocated all parameters to the global memory. The subroutine allows users to modify the coefficients locally according to the special conditions. Example:
subroutine readEG use meshelement use Strain3Dglobal implicit none real(dp) :: x,y,z,xp,yp,zp,dd,cc
