Issue using Openfast 2.4.0 with simulink

[ElioDaka]

Dear all,

I am trying to use openfast 2.4.0 in simulink. I'm currently running simulations using the executable of openfast 2.4.0 in windows. To use openfast with simulink I need the FAST_Sfunc.c that I have, but I need also the file FAST_SFunc.mexw64. This file does not already exists for my version of openfast. I have found the matlab file create_FAST_SFunc.m that I think is the one I need to create the missing file. The problem is that this matlab script tells: "Before running this script, you must have compiled OpenFAST for Simulink to create a DLL". Using the executable file of openfast I never compiled openfast using cmake or Visual Studio so I don't have the DLL that the script is asking for and I cannot find them. How can I solve?
Thank you
Elio

For OpenFAST 2.4.0, the create_FAST_SFunc.m file is located here: https://github.com/OpenFAST/openfast/tree/v2.4.0/glue-codes/simulink/src. You will have to follow the instructions to build the required DLL.

If you wanted to upgrade to a newer version of OpenFAST, the files Simulink binaries are already built and available for download on the releases page. You will need OpenFAST-Simulink_x64.dll and FAST_SFunc.mexw64, and for any release earlier than v3.1.0, you will also need MAP_x64.dll.
