请问对不同类型的杆单元长经比有什么一个比较优的数值范围没？
犹如网格单元一样，谢谢先作者: maple_ye 时间: 2005-9-15 18:41

不出現WARNING﹐就肯定是設置沒問題﹐其實很多東西可以去調整試一下。以前做分析時總是出現WARNING﹐改了一些Y設置及MESH就越來越少﹐當然重要的是要去查詢。作者: z30th 时间: 2005-10-27 15:26
The optimum L/D ratio for cooling line related beam elements is 2.5. Significantly lower L/D ratios can result in solver convergence warnings in the analysis. Significantly higher L/D ratios may result in solver convergence warnings and a reduction in solution accuracy.
The exception to this rule is gates,which must contain at least 3 elements,These elements will have a much smaller L/D ratio.
