VUSDFLD subroutine for storing charLength

[julius83]

Dear all,

I have a problem with the VUSDFLD subroutine. The purpose is very simple: to store both triaxiality and characteristic length to use them as field variables for a damage model.

The subroutine works well for the triaxiality ratio, which is calculated from the stress tensor (see attached file). However, the subroutine does not work when I try to store the characteristic length (charLength). Just add a line as follows: Lchar = charLength(k) and the analysis is aborted. What is wrong with this?

I attach the vusdfld field. Many thanks in advance!

Kind regards,
Julio

Hi,

By default Abaqus use implicit declaration of variables for FORTRAN subroutines.
Variables started with a-h and o-z are real and others are integers.

charLength array is real since it starts with x letter.
Lchar is integer since it starts with L.

You cannot assign real value for integer variable.

Change name from Lchar to charL and it should help.
