create sub routine from new or combine features from other subroutines 1

[GeorgeEllwood]

Hello,
I'm trying to get Abaqus to communicate with a Fortran based programme. I'd like to send information on nodal position and velocity to a Fortran programme and the Fortran programme should return forces in 2 directions to several nodes.
I've been looking at using user subroutines to do this but haven't had much luck with the sub routines that have been provided.
I had thought I had read in the Abaqus manual that as well as the sub routines that are provided with the abaqus, new subroutines can be created from scratch, however I can't find a reference to this now.
I was hoping to either create a new subroutine with aspects of the DLOAD subroutine and the sensor lookup function of the UAMP subroutine, or to incorporate the sensor lookup function of the UAMP subroutine into the DLOAD subroutine.
Does anyone know if that would be possible?
Thanks
George

Hi George,

new subroutines can be created from scratch

You cannot create your own subroutine, You can only use subroutines which are already implemented into Abaqus.

incorporate the sensor lookup function of the UAMP subroutine into the DLOAD subroutine.

There is no possibility to use sensor lookup function with other subroutine than UAMP.
But you can use both subrotuine (DLOAD + UAMP) in parallel and exchange all necessary data with common block.
For instane you can use user define amplitude not use by any keyword and Abaqus will call UAMP subroutine, you will get access to sensors lookup table.
