error #6236: A specification statement cannot appear in the executable section

[Mousumi_G_]

Hello:

I am writing a user subroutine, UMAT, for Abaqus where I need the UMAT subroutine to update and use my own specified stiffness matrix and solution dependent state variables.

I am attaching the fortran file. This is the error message I am getting!

umat_sdvini4.f(41): error #6236: A specification statement cannot appear in the executable section.
      integer i, j
------^
 Intel(R) Fortran 15.0-1684
compilation aborted for umat_sdvini4.f (code 1)

If any of you can help, that would be great!

Thank you very much,

Mousumi Ghosh

You need to use the double colon in declarations that contain initializations. For example,

     real :: f_i=1.0e-10

Without that double colon, in fixed form source, that statement is the same as

     realf_i = 1.0e-10

which sets the implicitly typed variable realf_i to the value.

Make sure that no source line extends beyond column 72, or use a compiler option to allow longer lines.
