Dear All,
In paraview, can we calculate the area of the surface of iso-contour ? I checked the user's guide but failed to find an answer. Does anybody have some experience in this issue? Thank you so much. |

Hi hz283,
Have you tried the "Integrate Variables" filter? Best regards, Bruno

Thanks, Bruno. I check its explanations online. It can calculate the integration of a quantities. But my problem is: there is an 3D iso-contours (corresponding to scalar x=0.5 for example), on this iso-contour, I also make it colored by another quantity, for example y. y will change from e.g. 100 to 1000 on it. Now I would like to calculate the the area on this iso-contour which correpsonds to 500<y<700. Can it be realized?
Thank you for your help! |

Hi hz283,
Have you tried the "Threshold" filter before the "Integrate Variables"? Best regards, Bruno

Thank you Bruno.
After I tried the Threshold and then got the got the following attached figures. Now I would like to calculate the area of this contours (just the area and nothing to with the physical quantities). When I apply Integrate Variables, it showed that following dialogue. Actually I searched it filter online but found that there are very few introduction about it. Thank you and have a nice weekend. |

Hi hz283,
Change the "Attribute" entry to "Cell Data" and you should then see the "Area" column. Best regards, Bruno

Hi all,
I can see that Paraview can compute the surface area of an iso-contour. Does anyone know if the volume enclosed by the iso-contour can be calculated? Thank you. Best wishes, EH |

Greetings ehooi,
The filter "Integrate Variables" is able to calculate the volume of ... a volume It will be shown in the "Cell Data" entry of the spreadsheet as well. But the problem is how to get the cells that are inside said isosurface. For better or for worse, ParaView has got two filters for this:
Best regards, Bruno
