Hi Manuel,

the force field in OpenLB is actually a force over reference density, thus it is equivalent to an acceleration. To convert your gravitational acceleration you can use the term

converter.getPhysDeltaT()*converter.getPhysDeltaT()/converter.getPhysDeltaX()

See you at the Spring School!

Best,
