Hello to all,
I need to calculate volumes of two mesh and i can't use the usual command checkMesh because it gives to me the same results because it doesn't show enough decimal digits. Here my case: in the first pic there is my original geometry with straight walls, in the second there is the modified geometry with an irregular wall. The volume change in the second case is very little because inwards and outwards displacements compensate themselves but not totally. Now, how can i know the little volume variation? The irregular wall is a distinct patch, if i show it and not the others can i calculate its volume? Thanks for help |

Hi,
Use integrate variables filter and from the array that pops up, click cell data and find a row with the volume. Regards, Mikko |

Hi Mikko, thanks for your answer but I'm afraid I did not understand.
Could you be more precise? Many Thanks |

Open your data file in ParaView. Press CTRL+SPACE, write "integrate variables" and press ENTER. Apply the filter and new screen pops up with tabular data that has only one row. Choose Attribute->Cell Data and you see one row of data with Volume column which is the volume of your mesh.
