Dear Renato,
The SDK does not have tools for creating .zsam files.
However, SAM does create files that you can use to duplicate a SAM simulation from the SDK. When you run a simulation in SAM 2014.1.14, it creates a text file in the folder C:\Users\\.SAM\ssc with a list of all of the input variables with their values for each SSC module called by the simulation. It also creates a set of files that assign values to the SSC inputs in the LK scripting language as well as for the Java, C#, Python, and MATLAB language wrappers. You can use those files to get the SAM input variables into your SDK model.
Best regards,
Paul.
