Block flow rates change after zone design

Hello, I'm trying to do a project, before asking to size the zone branch, the flow rates of the blocks coincide with the areas. After selecting the zone branch to size, the flow rates decrease significantly, thus sizing everything else in the wrong way.
I've already checked several points but I can't find the point where I'm going wrong. Could you help me?

To make my steps clearer. I've already done a project with the original irricade, without its own settings, the way it is downloaded and I didn't have this problem.
After that, I started configuring irricad to adjust my company, I made changes within irricad and in the database.
After these changes the problem appeared. I don't know which step it happened from. Then I tried to do it again with the original database and it also presented the same problem.

Hi Guilherme,

Prior to design, flows may be quoted in Irricad based on the nominal flows from the database e.g., SDR for tapes.
After the design process the actual flows are used where appropriate. You may have a mismatch between these in your database.

One thing to note, for instance, is that the nominal SDR for tapes should be entered per 100m of tape.

It should be relatively easy to check if any specific tape or outlet is operating under the desired conditions and giving the expect flows.
If they have the 'correct' pressure but the flow is incorrect, this suggests a problem with the hydraulic parameters in your database.

Regards,

Dan
