Hi,

I've run in to a recurrent error from these forums but can't seem to find a solution anywhere.

On running a system with a large number of BQs I'm presented with the following error:
HF1D:  Insufficient scratch space.

        needed                 21780392

        allocated              20000000

No matter what I change the memory setting in my input too, the "allocated" setting does not change. I also recompiled with LARGE_FILES=TRUE with no luck, and also tried direct calculations, just to try and decipher if it was a specific HDD or memory problem. Still the same message appears with the same values.

Can someone provide a sensible solution for increasing this "allocated" variable so I can run the calculation?

Many thanks!

Andy
