I have a vtu file that contains a Lagrangian curve, but when I import it into paraview, I find that the visualized result is a broken line, what should I do to visualize it as a curved line.

**Add** : A similar method is also applicable to Lagrangian triangles?

Hi @olwician,

Welcome to the ParaView discourse! Thanks for posting your question.

Is it possible for you to share your data set?

I think the answer you might be looking for can be found in the “Nonlinear Subdivision Level” property in the `Miscellaneous` section of the “Display” properties.

Set to 1 (the default):

Set to 3:

Hope that helps!

Best regards,
