21. The procedure involves building a mesh and solving the same on a computer using a finite volume approach. 22. The discretization of this is typically done with either the finite element method or the finite volume method. 23. If " k " = 1, the curvature is positive and the Universe has a finite volume . 24. In these cases it is mandatory to avoid the local forms of the conservation equations, passing some finite volume one. 25. It is not known whether all hyperbolic 3 & ndash; manifolds of finite volume can be constructed in this way. 26. ESP-r calculates building performance values based on a finite volume approach where it solves a set of conservation equations. 27. Thus, let us consider a system S in the form of a closed domain of finite volume in the Euclidean space. 28. The spatial location of finite volumes used in the calculation are indicated by j-1, j and j + 1. 29. When the manifold is compact or of finite volume , the Mostow rigidity theorem states that the fundamental group determines the manifold. 30. In any finite volume , the integral is replaced by a discrete sum, and the variance of the integral is } }.
