Dear All,
I am trying to run the VUMAT interface by Prof. Binen with the Sand Hypoplasticity. However, when I run the simulation Abaqus returns the following error: “Problem during linking – Single Precision Abaqus/Explicit User Subroutines. This error may be due to a mismatch in the Abaqus user subroutine argument”.
The versions of the programs that I am using are: Abaqus 2020, the visual studio 2019, OneAPI compiler v2022. When I run the Abaqus verification, it says PASS for everything (also subroutines), so I assume they are correctly linked.
Someone had the same problem and knows how to solve it?

Dear Giada Orlando,
Hopefully, your problem is already solved. But, I faced the same issue a while ago. If the command “abq2020 verify -user_exp” gives you “PASS”, then the problem is hidden in the subroutine. One quick action would be making a Dynamic-link Library in Visual Studio with your VUMAT and checking if it compiles.
Best Regards,
Ahmad
Dear Giada,
In order to solve this problem, you should replace the function “stop” with “call XPLB_EXIT” in your VUMAT.
The corresponding answer for the UMAT can be found here:

Kind regards,

Thank you!
Dear Giada,
May I ask where I can obtain the VUMAT interface for sand hypoplasticity developed by Prof. Binen? Thank you very much.
