How to Use this example project

Windows:

If DPF was installed as part of a normal Ansys Software installation, the
required .dll files are available for running the DPF capabilities

you can create a .bat file to laucnh Visual studio with these lines:

set AWP_ROOTDV_DEV=C:\Program Files\Ansys Inc\v241
set PATH=%AWP_ROOTDV_DEV%\aisol\bin\winx64;%PATH%

start "" "C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\Common7\IDE\devenv.exe"

and then load the dpf_csharp_client.csproj

dpf_csharp_client.csproj
