Several New Difference Schemes for Solving Fourth Order Parabolic Equation
【摘要】 利用加耗散项的方法,提出解四阶抛物型方程的若干新的差分格式,研究它们的局部截断误差阶及稳定性.数值例子表明,格式是有效的.
【Abstract】 In this paper,several new difference schemes for solving fourth order parabolic equation are developed by using dissipative term,and their orders of the local trumcation error and stability are discussed.It is show that schemes are effective by numerical examples.
