Hello,

I’m new to paraview. I recently got a problem while using paraview to visualize the results.

I run the simulation with Europlexus software and write out the \*.vtu file.  
When I opened \*.vtu file with paraview, it worked properly. However, I couldnot view the “ball” as it should be.

I think that it could be a problem related to circle surface visualization in Paraview. Does anyone has any suggestion please?

Please find in attachments:

- Q1-1: paraview results
- Q1-2: reference result by Europlexus
- Q1.vtu: vtu file

Thank you in advance[Q1.vtu](https://discourse.paraview.org/uploads/short-url/rIH4dyFxtVWWRjCIYOiiuJW87kB.vtu) (756.2 KB)

The “ball” is not exported by europlexus. Nothing ParaView can do about.

Thank you Mathieu for your quick answer.

It seems that the center of the “ball” is exported, am I wrong?

Thank you very much

Thank you

Sure, recover the center and radius of the sphere, then add a a Sphere source using these values.

Here’s a state file that places a glyph centered at the point extracted using **Extract Selection**.
