Hi,

I've installed v1.5 on HECToR, the Cray XT4 in Edinburgh, UK, and it appears to be working fine, with
../OpenFOAM/OpenFOAM-1.5
../OpenFOAM/ThirdParty
as expected.

I now plan to install v1.6 in my OpenFOAM directory tree, so that my tree would become
../OpenFOAM/OpenFOAM-1.5
../OpenFOAM/OpenFOAM-1.6
../OpenFOAM/ThirdParty
as expected.

However, v1.6 comes with an updated version of ThirdParty.

Is v1.6's ThirdParty backwards compatible? In other words, if I get rid of
v1.5's ThirdParty directory and replace it with v1.6's ThirdParty directory,
will v1.5 still work (perhaps after recompiling/relinking)?

Alternatvely, do I need v1.6's ThirdParty to run v1.6 or can I simply use
v1.5's ThirdParty?

Cheers,
Gavin
