[求助]ansys版本不同在计算上的影响？？
我最近用8.0 和9.0 版本算了一个模型，用的是同一组命令流，结果第一主应力一个是2兆帕多，一个是3兆帕多。 后来觉得奇怪，又换了一个模型，还是用的同一组命令流，结果两个版本算出的还是相差很多。<BR>请问各位高手，这应该是什么原因造成的？？？<BR>（线性，静力，实体，同一种材料，网格是自己划分） 共同关注ing回复：（daviddaiya）[求助]ansys版本不同在计算上的影...
应该不会存在这样的问题<BR><BR>建议把你的例子贴出来大家分析一下谢谢
<P>好的。网格全部为扫略划分，荷载是对转向管上表面30度内加表面力。命令流如下：<BR>/clear<BR>/prep7<BR>/title,the analysis of deviator with reinforcment <BR>et,1,solid45<BR>mp,dens,1,2600<BR>mp,ex,1,3.5e10<BR>mp,prxy,1,0.1667<BR>k,100,-0.37,-2.089863,-3.2<BR>k,101,-0.37,-2.1313,-3.5<BR>k,102,-0.37,-2.1505,-4.0<BR>larc,100,102,101</P><P>kwpave,100<BR>csys,4<BR>circle,100,0.06,,,360,24<BR>csys,0<BR>lcome,7,8<BR>allsel<BR>lsel,s,,,2,6,1<BR>lcome,all<BR>allsel<BR>lsel,s,,,9,13,1<BR>lcome,all<BR>allsel<BR>lsel,s,,,14,19,1<BR>lcome,all<BR>allsel<BR>lsel,s,,,20,25,1<BR>lcome,all<BR>allsel<BR>lsel,s,,,2,20,1<BR>cm,huani,line<BR>cmsel,s,huani<BR>lsel,s,,,huani<BR>al,huani<BR>allsel<BR>vdrag,1,,,,,,1</P>

谢谢
拜请高手指点！！ 关注中 <P>是个值得研究的问题。</P>新发现
好像在第3步分网时，8.0版本提示正常，9.0版本提示有单元超出了形状极限，并且生成的节点总数与单元总数两个版本也不同。<BR>!选择转向快中部单元划分<BR>allsel<BR>vsel,s,,,2<BR>vplo<BR>esize,0.03<BR>vsweep,all,25,26<BR>
