Hi everyone, I am trying to model an irrigation system with 100 x 100 m modules in Hammer. Each module has 200 parallel pipelines and each pipeline has 200 drippers. It's a quite simple model but it will take me a lot of time to draw this node by node. is there a smart way to draw systems like this? Thank you
Hello Jonatan,
Do you have access to MicroStation, AutoCAD, or ArcMap?
If so, I would create the elements in one of those platforms.
You would just need to place a node (cell) and a line. Then use the array tool to create copies of those elements.
Then go into the standalone Hydraulics and Hydrology product and use the ModelBuilder tool to import those elements into a model.
Make sure to enable "Establish connectivity using spatial data"
See: Using ModelBuilder to Import External Data
Could you provide some background on what kind of transient event you are trying to model in HAMMER?
It appears that you already have these elements laid out by the images you provided.

Usually, the velocity in the lines with the drippers is so low that you don't need to model it in your analysis. If anything, these drippers act as air releases/orifices and tend to dampen out transients.
I would first run the analysis on the large transmission mains and model each branch as a single user.
