Webevolution equation have been checked and the time and space step re nements needed have been identi ed with reference to a simple SDOF problem. Then, some preliminary numerical results have been obtained for a masonry tower represented as a simple beam model, applying a seismic action and accounting for the uncertainties of the Young s modulus. WebThe discretization of the convective terms is based on a coupled time and space approach by using a one-step (OS) scheme, developed below the Lax-Wendroff approach until correcting the successive modified gleichung. A property preserv- guiying (MP) criterion is added in purchase to locally relax the TVD contraints for such schemes. can i freeze nanaimo bars
