Abaqus requires additional software to be installed on Windows in order to make use of custom User Subroutines. You will need both a C++ compiler and Fortran compiler. Only specific versions of these compilers are officially supported by Simulia for use with each version of Abaqus.

Microsoft Visual Studio 2017 (Visual C++) is a Qualified Platform.

The Abaqus 2016 installation process is significantly different than in previous versions. This unofficial guide may be helpful if you're having trouble following the official instructions.

After some time you will have the following files:

2016.AM_DOC_SIM_EstPrd.AllOS.tar
2016.AM_SIM_Abaqus_Extend.AllOS.1-5.tar
2016.AM_SIM_Abaqus_Extend.AllOS.2-5.tar
