Hi guys,
I have a pretty large model, in where I connected my hydrants with batch pipe split. The mains have user-defined length. Some hydrants have a lateral pipe (with calculated length), with a junction placed over the main. After splitting thousands of pipes, some of the new pipes (~100) had negative or zero length.
I made a query to filter these and group edited the length to 0.1m, to get through validation.
Have anyone faced this problem before?
Is there a numeric limit of the minimal distance between two junctions? - This might be the source of the problem.
Best regards,
Hello Attila,
I'm having some difficulty understanding your problem. I experimented with this and was not able to reproduce the problem, so I may not be clearly understanding the process you're using. Are you able to share a small example with steps to illustrate the problem?
You mentioned that you have some hydrants already connected to a lateral pipe, connected to a junction on the main line, which would mean that the batch pipe split is not needed. If the distance between those hydrants and the junction on the main (that they are already connected to) is less than the Tolerance field in the Batch Pipe Split tool, you could end up with some unexpected results. I'm unclear if this is what is happening, though in my testing in the latest version (CONNECT Edition) it did not result in zero or negative lengths.
There is an option under Tools > Options > Hydraulic Model to "Round Length to Nearest" but from your description I do not believe this is related.

Hi Jesse,
I uploaded a snippet of my model that contains some problematic laterals. There is a selection set, for the pipes to split. Tolerance was set to 0,5m. The precision of unit display has to be set to a couple of decimals, to appear as negative. Otherwise, lengths are rounded to 0.
Since I have a workaround, it is not an urgent issue. Anyway, a "batch junction merge withing given tolerance" addition would be nice and easy to handle these, hence these junctions are extremely close to each other.
