modeling power system

[TECNOMODEL]

I have some difficulties to properly model a system of power channels, to pre-analysis control it gives me error saying that every injection must be connected to a carrot.
I have a mold with sixteen prints, created starting from the first comprehensive injection point and duplicating the others in the desired positions.
I then created the carrot in the middle of the mold, I defined the type of the injection point, selected each point and applied the property.
I then start to model the channels, starting from the center of the carrot and setting the final point of the first section.
then select the final point as the initial of the second section, imposed the final point of the second section and so on until you select final point and point of injection to close the whole.
But that message comes out.
What am I wrong?

I haven't been using Moldovaflow for some time, but I try to help you.
you have to have a little patience and try to find where the flow stops. Maybe before you start doing the 16 prints, try making one footprint.
start saving your work on a different folder, delete duplicate parts and try with the only first footprint plus carrot and channels. if it is all connected the analysis will begin. if there are interruptions will give you the error message, in this second case try to delete and redesign a channel at a time.

Thank you for the answer, I had arrived too.
Is there no way to figure out where the error or the open knot is?
I think I'm a little desperate. . .

among the various geometry control tools and elements there is also one to check if some element is not connected.
allows you to quickly verify if the 1d elements of runners/gate are connected correctly.
I don't remember the name of the command, a lustro passed around.

mesh connectivity diagnostics seems to have found on the internet
if you only care about channels, help hide unwanted layers
tips for creating channels:
use filters to select only certain entities (e.g. points, nodes)
if there are problems trying the tool to make the knots coincide after checking where the problem is

return to the thread after having, more or less, understood how to model the feeding system.
the only dark point is the connection between injection points and power channels.definite injection points and, for each of them, I define the size of the injection point and its type.
graphically, however, I do not see the geometry of the injection point but only the cone that identifies it, which already leaves me perplexed.
then model the last part of the power channel, connecting it to the previously created channels and the injection point.
here however, the only element that makes me select is the node supported by the geometry of the cavity, I cannot select the final node of the injection point.
the system is closed but gives me a warning message because the geometry of the channels touches the cavity, even if it allows me to do the analysis.
Where am I wrong?

second question, sometimes I get the error because the power system is not connected in every point, but it does not express it clearly and, above all, does not highlight the point where some elements are not connected.
I don't find commands to make a verification of the various connections or integrity of geometry, are there or not I find them?

ciao technomodel,I just read your post now.
are Moldovaflow user for 10 years.
when you launch the analysis in the log that error gives you?

Hello stefano, thank you for the answer.
In the meantime I understood the hippo, changing the type of point I managed to connect correctly the whole system.
