title: Using subroutines written in Fortran 90 with Abaqus Standard
body: <p>I am using Abaqus with user-defined subroutines. To the best of my knowledge, Abaqus Standard or Explicit can be used with subroutines written <strong>specifically</strong> in Fortran 77 language, <strong>not</strong> the improved Fortran 90/95 language! Is there a way how to use Fortran 90 and later with Abaqus?</p>
