What does it mean user subroutine (Groovy)?
Altair EmployeeBefore the Flux 11.2 version, user had to write user sub routines in Fortran and compile them using a Fortran compiler. Moreover, he also had to define a user version in Flux.
Nowadays, there is no need any more, either to buy a Fortran compiler or to create a user version. The use of user sub routines is hence simplified.
Indeed, if the user performs any modification in his Groovy file, all he has to do is to save it and the Groovy file will be automatically compiled during its next use.
It is still possible to use old user sub routines written in Fortran. To do this, the user needs to go to options/access paths/user version from the supervisor. Then user selects the directory in which are stocked the directory which the suffix is “.f3d_usr”.
