Prioritizing when modeling

Hi

In the case that one is modeling a water-distribution system for say an island but is restricted by the amount of pipes that the license allows one to model. How does one then prioritize in order to decide which pipes to model and which not to model.

  • Unless you're working with a tiny island where all your proposed improvements are only wroth say $10K, you are probably looking at spending a few million dollars for improvements. So eth upgrade cost should be small compared with project costs. Plus, it will save labor costs for your modeler to skeletonize the model. The cost of upgrading may pay for itself.

    But there are situations where you can skeletonize a model  and still have a good model. This is often the case where you have runs of say about 5 pipe in series with no branches. Here you can use our "series pipe merging" in skelebrator to combine those pipes into one. Even with your small pipe version, you can use skelebrator to trim down you model and see if if performs satisfactorily.

    The key is that you don't want to remove anything from the model that could be important for your study.

  • Thank you Tom. I have another question. Say my WaterCAD licence allows me to model up to 2000 pipes and the system i want to model consist of lets say 8000 pipes. Could I create a layout of all 8000 pipes and use the skelebrator to get it down to 2000 or less or would WaterCAD not even allow me to create the layout with 8000 pipes since that's more then 2000?

  • Hi Christen, the license check on the number of pipes is only done on compute, so you would indeed be able to import and/or layout 8000 pipes, then use Skelebrator to get it down below 2000.

    Note however that Skelebrator is included with a WaterGEMS license, so if you have WaterCAD and do not also have access to WaterGEMS, you would need to upgrade to WaterGEMS in order to have access to use Skelebrator, as mentioned in this article: How can I reduce the number of pipes in my model?

  • Hello Jesse I have another question lets say I have a WaterCAD licence that allows me to model up to 2000 pipes. Could I create multiple models of different sections of the water distribution system and simulate the sections separately or am I limited to only one model with a limit of 2000 pipes?

  • I would assume that it's possible since n you stated that the license check is only done on compute.
