TL;DR: In this paper, a new computational method, the immersed boundary-lattice Boltzmann method, is presented, which combines the most desirable features of the lattice Boltzman and immersed boundary methods and uses a regular Eulerian grid for the flow domain and a Lagrangian grid to follow particles contained in the flow field.

TL;DR: In this paper, a new method for network analysis, the "force density method" is presented, which is based upon the force-length ratios or force densities which are defined for each branch of the net structure.

TL;DR: In this paper, seven form-finding methods for tensegrity structures are reviewed and classified, and it is concluded that the kinematical methods are best suited to obtaining only configuration details of structures that are already essentially known.
Abstract: Seven form-finding methods for tensegrity structures are reviewed and classified. The three kinematical methods include an analytical approach, a non-linear optimisation, and a pseudo-dynamic iteration. The four statical methods include an analytical method, the formulation of linear equations of equilibrium in terms of force densities, an energy minimisation, and a search for the equilibrium configurations of the struts of the structure connected by cables whose lengths are to be determined, using a reduced set of equilibrium equations. It is concluded that the kinematical methods are best suited to obtaining only configuration details of structures that are already essentially known. The force density method is best suited to searching for new configurations, but affords no control over the lengths of the elements of the structure. The reduced coordinates method offers a greater control on elements lengths, but requires more extensive symbolic manipulations.

TL;DR: A version of immersed boundary-lattice Boltzmann method (IB-LBM) based on the lattice BoltZmann equation with external forcing term is proposed, which shows that there is no any penetration of streamlines to the solid body in the present results.
