SewerGEMS Load viewing

Question

Hi all I have imported through the loadbuilder my loads for the network. I have two questions: 
 1. Can I view on the plan map where these loads are, or do they not have x,y co-ordinates and only can be viewed on the maintenance holes that they are connected to. 
 2. Not all the loads were imported is there a distance adjustment that I need to do? 
 
 Cheers 
 Lee

Hello Lee, 
 1. Can I view on the plan map where these loads are, or do they not have x,y co-ordinates and only can be viewed on the maintenance holes that they are connected to. 
 The location of the loads should be viewable by applying the shapefile you used as a background file. The appearance of this will naturally be related to the appears of the shapefile, but you could get an idea of where they are located. The values being applied will not be displayed in the background. 
 To see the values applied, you can look at the Sanitary Load Control Center (found in the Tool pulldown menu) or annotate the nodes with the field "Flow (Local In)" which represents local inflow at a manhole that doesn't come from upstream links.

Hello Lee, 
 
Thanks for sending the data. The program seems to be working as designed. With the Nearest Pipe method, it will split the loads between the two manholes attached to the pipe. How this distribution works will depend on if you choose "Equal Distribution" or "Distance Weighted." 
 
In addition, you are getting a single collection with the sum of the loads applied to a node. In other words, if two points are "nearest" to a single pipe, the loads on the two points are summed up into a single value. The distribution of the loads between the nodes complicates this and makes it difficult to look at a manhole and see the individual loads. 
 
That said, if you sum up the loads in the shapefile and the loads after being applied to SewerGEMS, the add up to the same value, so it does appear that all of the loads are being applied. 
 
Please let us know if you have any questions. 
 
Regards, 
Scott

Hi Lee, When Loadbuilder assigns loads, it creates a field (or two fields, depending on the method) to the shapefile (or geodatabase) indicating the spatial allocation. This allows the user to use the "use previous run?" option in future Loadbuilder runs, to automatically pick up on these assignments and update any changes to the loads in the shapefile, instead of having to re-compute the spatial proximity. It will also allow you to confirm exactly where each load was assigned. Here is a related Support Solution: http://communities.bentley.com/products/hydraulics___hydrology/w/hydraulics_and_hydrology__wiki/17570.how-to-view-demand-or-load-allocation-after-a-loadbuilder-run-solution-500000081390

Re: 2. Not all the loads were imported is there a distance adjustment that I need to do? 
 
Depends on what loadbuilder method you used, but if for example you used billing meter aggregation, maybe some of your loads (points representing the users) were located beyond the extents of the service area polygons for your manholes. Adding the service area layer as a background would help visualize and confirm. If this is the case and you used the Thiessen Polygon tool to generate the service area layer, you may need to specify a boundary polygon covering all manholes or extend the buffering percentage. 
 
If this doesn't help, then as Scott said, it would help if you could provide a bit more information. If you need to send in the data (zipped), you can use the process in the below link, or attach to your reply if you prefer.
