Solution
This interface can be used to gain access to the simulation options and execution interface. This interface is embedded within the ActiveCircuit interface, requiring the exposure of this interface before getting access to it.
Example
% Create DSS object
DSSObject = actxserver('OpenDSSEngine.DSS')
if ~DSSObject.Start(0),
disp("Unable to start openDSS");
return
end;
DSSCircuit = DSSObject.ActiveCircuit;
DSSSolution = DSSCircuit.Solution;
