as stated in , it is necessary to enlarge the particle for the consideration of the contact. You can do this using
particle.setField<NUMERICPROPERTIES, ENLARGEMENT_FOR_CONTACT>( /* choose a value */ );. Otherwise it is to be expected that the incompressible fluid slows down the particle so that there is no contact with the wall, especially for high resolutions.
