Reply To: Static Variable in User Defined Function

[Andreas Koutras]

Hello It seems that you are trying to implement a subroutine "rebar_bondslip_get_force" in the umat package. The umat subroutines are written in Fortran. To define a global variable, you can write a module in the umat file. For example, to define an integer global variable "icounter", you can copy following lines in dyn21.F. You can look online for general information and examples on Fortran commands. I hope this helps.
module example
implicit none
save
integer icounter
end module example
