User-supplied subroutine USRIFC
By chalmers - Posted on 08 September 2010
Hi,
Does anyone know how to CALL the following data into a user-supplied subroutine USRIFC:
1. Local axes of the interface element
2. Nodal deformations of the interface element.

The relative displacement vector at start of step and the total tractions at start of step are passed by DIANA to the subroutine for each step and integration point as u0(nt) and tra(nt) respectively. The tractions can be updated in the subroutine, see Material Library paragraph 11.6.
The local axes of the interface element should coincide with your material reference axes, so you should check this in your preprocessor.
If you need to get other data from DIANA's database library you should use call gtc(path, gval, len), see Analysis Procedures Appendix A.4.4.1.

I hope this is helpful.
