Re: [Anuga-user] Issue in anuga software

[Gareth D. <gar...@gm...>]

Hi Shuvam,

I would guess that 1.3 million triangles will exhaust the available 
memory (4GB). ANUGA is not very conservative in its use of memory. I 
expect this memory would be residing in the values of "domain.quantities".

Your best bet is probably to try to access to a larger machine with more 
memory -- or, to run the model at lower resolution (or perhaps only use 
high resolution in a small area). The number of triangles should scale 
linearly with (1/max-triangle-area), as should the required memory (at 
least approximately).

Cheers,
Gareth.
