RectilinearGrid To Volume

[Sathya Krishnamurthy (CSCS)]

Hello All

In my efforts to get the volume out of the RectilinearGrid, I have come
up with this code below.

But, on running this..the code crashes with the following error message  

%Virtual memory exceeded in `new'

and the program quits.

Can somebody kindly point to me.. where I am making the mistake ?

Thanks a lot
cheers
Sathya
