If Opensees solvers are installed in C:\OpenSees-Solvers, STKO will automatically detect those solvers. Otherwise, use the Kits command in STKO to tell STKO where the OpenSees solvers are.
NOTE: If you want to use the MPCO Recorder for post-processing in STKO, you need to have HDF5 1.10.1 DLLs installed in a location visible to your OpenSees solver. Option 1 of the above list takes care of all necessary dependencies. If you don’t know how to install all of the necessary dependencies, you can use option 1.
