Application of Finite-Volume Method in Torsional Analysis of Prismatic Bars

In present paper the torsion of prismatic bars has been investigated by the finite-volume method (FVM) for the first time. One of the distinguished features of this method is the ability for treatment of complex geometries. The Poisson equation has been solved on a cell-centered mesh with consistently derived boundary conditions. For this purpose a FORTRAN 90 code was written. The shear stresses at various locations of cross-section were determined. Also، thorough comparisons have been made with the conventional methods to verify the superiority of the present scheme in terms of convergence reduction and solutions accuracy.
