Modeling of the movement and stress distribution of a line-shaped item in a vortex

The purpose of this project focuses on the movement of single and multiple nodes in a vortex. Vortex exists in the form of natural free vortex or forced vortex induced by external forces. Vortex is used in fluid applications ranging from industrial pumps to materials separator using vortex movement...
