SDVINI allows you to define the initial solution-dependent state variable fields.
Helius PFA has the capability to forward on to the custom Abaqus user subroutine SDVINI. In other words, you can use Helius PFA in conjunction with the Abaqus SDVINI subroutine.
The SDVINI subroutine can be called to define the solution-dependent state variable fields for material points, shell section points, contact slave nodes, or user elements. Refer to the Abaqus Documentation for further details.
To use the SDVINI subroutine with Helius PFA, you need to include SDVINI with the Helius PFA subroutine build. Those instructions can be found here for Windows or here for Linux.
