METHODS OF CONNECTION RECONSTRUCTION FOR ARBITRARY POLYHEDRAL COMPUTATIONAL GRID

VANT. Ser.: Mat. Mod. Fiz. Proc 1997. Вып.2. С. 3-16.

      A method of 3-D irregular grid local reconstructions has been proposed along with its program implementation algorithm. The method is based on two grid reconstruction operations — pasting two meshes having one common face and cutting a certain mesh into two by a given plane.
      The criteria of either operation application are given and analyzed.
      Two test calculations with a program of 3-D irregular grid local reconstructions used have been carried out; the computed results are given.



INTERPOLATION OF FUNCTIONS AND SMOOTH RECONSTRUCTION OF CURVES RETAINING THE MONOTONICITY AND CONVEXITY

G.P. Prokopov, O.I. Sofronova
VANT. Ser.: Mat. Mod. Fiz. Proc 1997. Вып.2. С. 71-78.

      The elementary but important for applications problem of construction of spline passing through the giving set of support points is under consideration. The rational splines construction approach allowing to retain the monotonicity and convexity of constructing curve of C class is suggested. The advantage of the algorithm is automatized definition of all parameters of splines.
