Hi all,
I am trying to integrate the volume contained
within an isosurface. I have seen some previous post
addressing something similar but not quite like this.
I have an scalar field on a regular grid that I am
trying to work out the integrated volume limited by
an isosurface of the same field.
I have tried the measure module but, it seems
that it computes just the volume, but not the integral
( i.e. element_volume*data_value ).
Also tried the include module with the field
by just including the points with values less than
the desired isovalue but the approximation is quite bad
because the connections of points that are not completely
below that value get marked away from the grid without
interpolation.
Tried as well the integrate volume macro from
the bonus pack. The problem is that if you use the
isosurface as the volume, the scalar field gets mapped
onto the isosurface, so what you get is the surface area
and not the volume.
Has anybody got more ideas on the problem?.
Many thanks.
