Vtk import and real mesh volume

[henri meric]

Hi every one,

I would like to know how to get the volume of a mesh
the mesh is built with meshpy (not my work) and save as a vtk
I need as a first step to get the volume of the mesh

I can't find a way to do it quickly.

Hope anyone would be able to help me.

thanks

Hi,

define function

def get_volume(pb):
volume = pb.evaluate('d_volume.5.V(u)')

and set it as the pre_process_hook function in options

options = {
'pre_process_hook' : 'get_volume',
}

Regards
Vladimir
