Hi all

I simulate gas dispersion in CFX, I produce isosurface of gas that has same concentration. I like find the volume and mass of gas that exist in my isosurface, its important for me from safety point.

An isosurface is a 2D region and as such has no volume or mass. I think what you want is an Isovolume. To create an Isovolume, create a Volume object in CFX-Post and pick the Isovolume option.

thanks robin, thats true, I'd like it
