A swollen glandular saddlelike region in the epidermis of certain annelid worms such as the earthworm that secretes a viscousfluid to form a cocoon for their eggs.
In this paper a reliable commercial CFD software FLUENT is introduced to simulate the viscousfluid field around the trimaran sailing in shallow waters.
