Hello, everyone.
I am simulating a river with two columns of a bridge inside.
In order to get the coordinates of the columns, I use python to get 20 points at the edge of the circle. I do the scatter plot using matplotlib which is ok.
But when I import them into Blue Kenue, it is not a circle shown in the figures attached.
As well, I find that points of boundary condition in .bc file don't match the points at the edge in Blue Kenue and I am not sure that it's normal considering the shortcoming of Blue Kenue in visualizing.
BTW, is it a problem that the scale of the river is too big comparing with the columns.

This is related to the precision of node coordinates which are not well managed by BK nor by Telemac if you work with a mesh in simpel précision. Try to shift the model, this will solve the problem Regards

hyoukai	THX, it has been done. I was assuming that it's a problem of shifting. But I couldn't find a way. But right now it's OK! THX!
