Hello. I'm beginner of EPANET-Matlab toolkit.

The purpose of using this toolkit is optimizing sensor networks of pipe networks. I want to use junction as a pressure or head sensor, so I should add or delete junction or pipe. However, there are some problem to add the junction. (I can get output of the system response...) I already followed the addnode functions written in 'epanet.m' file, but I could see only error message. Here are the functions I used.

1. d.addNodeJunction(obj,juncID) -Command: d.addNodeJunction(‘20180329_practice_KIMMtemp.inp’,50); -Error Message: Too many input arguments. -Command: d.addNodeJunction(‘20180329_practice_KIMMtemp.inp’); -Error Message: Struct contents reference from a non-struct array object.

2. d.ENaddnode(obj,juncID,obj.ToolkitConstants.EN_JUNCTION); -I don’t know what does ToolkitConstants mean.

3. d.addNode(obj,1,newID,X,Y,newElevation); -Command: d.addNode(‘20180329_practice_KIMM_temp,inp’,1,50,300,300,0); -Error Message: No appropriate method, property, or field ‘addNode’ for class ‘epanet’.

4. d.ENaddnode(obj,nodeid,nodetype); -Command: d.ENaddnode(‘20180329_practice_KIMM_temp.inp’,30,‘Junction’) -Message: No appropriate method, property, or field ‘ENaddnode’ for class ‘epanet’.

As I mentioned, I only followed the functions written in 'epanet.m' file, so I don't know what is the problem. Could you explain how to use the functions that add node(junction) with EPANET-matlab toolkit or give me a manual of that, please?

Thanks for your effort!

Thank you!
