Thank you!
I did as you said yesterday.
But there are problems in the river junction.
In Figure 1(example provided by telemac.org), the junction line is only one line between the Branch Channel and the Main Channel.
In our case(Figure 2), which is the complete junction figure of the branch and the main channel, we can combine them by T3 mesh generator, however, the line between them is not one line, there are several lines between them.
Figure 3 details the local figure which is at the top-right corner of Figure 2,Meanwhile,Figure 4 is the junction lines between branch and main channel in the middle of Figure 2.
Can you tell me how to deal with the junction like as the example case?
Thanks!
