Different Results 32-bit vs 64-bit

Recommended Posts

I've been doing some testing of a small model on different machines and have noticed that, for exactly the same model, I get different results on 32-bit and 64-bit operating systems. I am getting different warnings, mass balances, volumes etc etc. They are not wildly different but I would have thought that, using the same version of TUFLOW, I should get the same results. Has anyone else noticed this and is there a preferred approach?

This is a known 'feature'. The TUFLOW manual states "Slightly different results (mostly fractions of a mm) will occur between w32 and w64 for the same model" Given the small differences, it shouldn't really matter which version of TUFLOW you use. If you are using 64-bit computers at work, I would use the 64-bit version of TUFLOW.
