Hello,

There is a predefined variable available on edges called curv_spatial. I never remember the names of those types of quantities, but here's the trick: you can find the name of such predefined variables by creating a plot and looking among the expressions available for plotting (Here, by doing a Line plot and looking among the Geometry expressions), see the attached screenshot.

Best regards,

Jeff
