Test Solver

I'm begin with this libary and I found some Java samples tha can be converted to .NET. :
FlowSystemInterface pipe = new PipeFlowSystem();
pipe.setNumberOfLegs(10);
pipe.setNumberOfNodesInLeg(2);
...
pipe.createSystem();
pipe.init();
pipe.solveSteadyState(10);
...
It works. My question is about individual pipe legs. Notice that are created automatically. Correct? Can I create or modify manually , like
neqsim.fluidMechanics.flowLeg.pipeLeg.PipeLeg leg = new neqsim.fluidMechanics.flowLeg.pipeLeg.PipeLeg();
leg.setLongitudionalCoordinates(10, 10);
leg.setNumberOfNodes(2);
...
and asociate to PipeFlowSystem ?

Thanks
