Particle strength exchange scheme gives wrong solutions #3

There is less viscosity then there should be. Due to incorrectly ordered arguments in internally called functions.

Some work in commit dcf994dd9f6cdd5f9e857eee08522fdd98c8f61c. Argument ordering in internal calls swapped the viscosity and regularisation distance. This doesn't mean the code is actually correct however. Just less wrong.

PSE seems to give correct solutions, only not a whole lot of viscosity transfer seems to happen. Perhaps this is to do with case setup?
