Dear All, I am trying to run the VUMAT-UMAT interface provided on soilmodel.com (https://soilmodels.com/download/vumat_umatinterface-zip/) 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, and 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?
