by a comparison of the result with that of the analytical solution, the computational error of the numerical solution is discussed.
进行数值求解,通过数值解与精确解的比较,对计算误差的变化规律进行了分析研究。
the results of verifying calculation show that the analytic formula has smaller computational error as compared with computer numerical arithmetic, and therefore it is practical.
验证计算结果表明:解析公式与计算机数值计算法结果相比较,计算误差小,具有实用价值。
to avid this computational error , it comes forth finite contact elements analysis method.
为了消除这种计算误差,出现了有限元接触分析方法。
but with the increasing of the order of interpolation polynomials, serious oscillation phenomena will appear, which will increase the computational error and affect instabilities of computations.
