Hallo,

I am Nithin and working on my Thesis right now and i would like to know where can i find the details for Solution Dependent Variables(SDV) ex. SDV1, SDV55,SDV79.. stand for?.
Any help would be much appreciated.

Kindr regards,
Nithin

RE: Solution Dependent Variable(SDV) ex.(SDV1,SDV55...) stand for?

(OP)
Yup, tried most of it, SDV55 is related to slip factor in the materials, still not able to find the meaning for SDV79, i know its related to stress state of the material, but want to know what kind of stress is it related to.

RE: Solution Dependent Variable(SDV) ex.(SDV1,SDV55...) stand for?

Hi,

If you are writing a user subroutine, you can define user-dependent state variables. These are recalculated/tracked throughout your analysis and will typically vary from one subroutine to another. If you are using a specific subroutine and want to figure out what SDV1, SDV2, ... are you should open your fortran .f file, read your code, and see for yourself.

Good luck,
Dave

Hi Dave,

Many thanks for your suggestion, i will look into my UMAT subroutine and will see if there is any luck.

Regards,
Nithin

And @Ice Breaker, yup i am using UMAT subroutine to my model.

RE: Solution Dependent Variable(SDV) ex.(SDV1,SDV55...) stand for?

You need to understand the UMAT and everything *should* make sense. Given the kind of question you asked, I suspect this is going to be a non-trivial task and will take a substantial amount of effort on your part.
