  Star clusters are known to be formed in turbulent molecular clouds. How
turbulence is driven in molecular clouds and what effect this has on star
formation is still unclear. We compare a simulation setup with turbulent
driving everywhere in a periodic box with a setup where turbulence is only
driven around the outside of the box. We analyse the resulting gas
distribution, kinematics, and the population of stars that are formed from the
cloud. Both setups successfully produce a turbulent velocity field with a power
law structure function, the externally driven cloud has a more central,
monolithic, clump, while the fully driven cloud has many smaller, more
dispersed, clumps. The star formation follows the cloud morphology producing
large clusters, with high star forming efficiency in the externally driven
simulations and sparse individual star formation with much lower star formation
efficiency in the fully driven case. We conclude that the externally driven
method, which resembles a Global Hierarchical Collapse (GHC) scenario, produces
star clusters that more closely match with observations.
