Varying number of points in longitudinal section (POST) 8 years 8 months ago #20005

Hello everyone

I've been exporting longitudinal section (along my river axis) in POST for a few simulations, but the number of points in the export table changes from export to export (from 6000 to 7000 for example), whereas the mesh ans section line used for the export is the same.

Granted, this can be solved in Excel with a Vlookup or an interpolation function but i was wondering if there's a way to "freeze" the number of points used in the profile.

Thanks

So it's understandable if the mesh change but if the mesh and the section are the same, this means there is another methodology of computation. Maybe you could post an example... regards

sjl	Hello you're right but I've just noticed that the problem is that there are some random duplicates points, not always at the same spot, which shifts the values below (yellowed in the attachment) Thanks
