hello every one
i have a problem with abaqus subroutine
can i use hypoplastic umat file that prepared for palxis in this website in abaqus?
or the files must be specially prepared for abaqus?

Hey
I use the hypoplastic umats (for sand) from this webpage for Abaqus and in general they work fine.
To my understanding there is only a minor difference between umat for Plaxis and Abaqus. Somewhere in the code it is even highlighted which lines need to be commented/uncommented.
If you have really some problem with running umat on Abaqus you would need to give more details on what is the problem.
Hope this helps at least a bit.
Regards
Piotr
dear Piotr
thank you for your answer
i will check it out my problem in detail
