Hello:
I am fairly new to Abaqus!
I am trying to write up a user subroutine (USDFLD) where I update the velocity of the fluid containing some particles in it.
For that, the formula I am using is Darcy's Law (but a little modified!). I am aware of the utility subroutine GETVRM. However, GETVRM only gives me all the pressure values (one time step at a time). I know by writing in array(1), I will access the pressure values of all the elements at once.
However, I want to access the difference in pressures across the elements that are placed side-by-side!!! I don't know how to get that via GETVRM!!!!
Could you please give me a hint or something?
Please and thank you very much!
Hello Yeqing:
Thank you for your answer!
I don't need the pressure values for the entire model, just the portion where the fracture is located!!!! I guess I can try to isolate the area using the coords(*) dimension limitation!!!
If you have any better idea, let me know!
And thank you once again!
