关于划分网格的问题.docVIP

liusl101 关于划分网格的问题我做的是一个实体划分的例子，但划分网格总是很慢，且让我毫无信心，那位大侠指点一下； 我这个有图形，但因为是通过另一台机子上网，故没考过来，还请见谅，你可拷过去跑一跑，谢了！！！ 还有，我想让它划分成六面体单元，并施加两条线荷载及10个集中荷载，兄弟不知是直接加在线上和关键点上，还是将这些附着在体上再加载。 ??还请Hekie及各位大侠多多关怀，小弟给各位先进鞠躬了。 ??fini /clear /prep7 ??blc5,2.44,11.56,50,70,42.5 /view,1,1,1,1 /pnum,volu,1 gplot blc4,0,0,4.88,3.56,42.5 wpstyl,0.005,0.005,-0.02,0.02,0.003,1,0,,5 cyl4,2.44,3.56,0,0,2.44,180,42.5 k,61,0.34,0, k,62,0.44,0.1, k,63,0.64,0.3, k,64,4.24,0.3, k,65,4.44,0.1, k,66,4.54,0, k,67,0.34,0,42.5 k,68,0.44,0.1,42.5 k,69,0.64,0.3,42.5 k,70,4.24,0.3,42.5 k,71,4.44,0.1,42.5 k,72,4.54,0,42.5 et,2,shell93 v,67,72,66,61,68,71,65,62 et,3,shell93 v,68,71,65,62,69,70,64,63 vlist,all et,1,solid95 vsbv,1,2,,,delete vsbv,6,3,,,delete ??vadd,1,4 vadd,2,5 wpstyl,,,,,,,,0 ??k,73,1.7225,0.3,40 k,75,1.7225,0.3,38.5 k,77,1.7225,0.3,37 k,79,1.7225,0.3,35.5 k,81,1.7225,0.3,34 k,83,1.7225,0.3,32.5 k,85,1.7225,0.3,2.5 k,74,3.1575,0.3,40 k,76,3.1575,0.3,38.5 k,78,3.1575,0.3,37 k,80,3.1575,0.3,35.5 k,82,3.1575,0.3,34 k,84,3.1575,0.3,32.5 k,86,3.1575,0.3,2.5 l,83,85,16 l,84,86,17 ??mp,ex,3,1.75e4 mp,ex,2,1.86e4 mp,ex,1,15.0e9 mp,prxy,1,0.12 mp,prxy,2,0.18 mp,prxy,3,0.20 esize,0.002,0 smrt,2 mshape,1,3d mshkey,0 vmesh,all krefine,73,81,2,3,,smooth,on krefine,74,82,2,3,,smooth,on lrefine,16,17,1,3,,smooth,on ??fini /solu da,1,symm,0 da,2,symm,0 da,3,symm,0 da,4,symm,0 da,5,symm,0 da,6,symm,0 sfl,16,pres,-90000,-90000 sfl,17,pres,-90000,-90000 sflist,16,pres sflist,17,pres fk,73,fy,-200000 fk,75,fy,-200000 fk,77,fy,-200000 fk,79,fy,-200000 fk,81,fy,-200000 fk,74,fy,-200000 fk,76,fy,-200000 fk,78,fy,-200000 fk,80,fy,-200000 fk,82,fy,-200000 solve save ? hekie 载荷是可以直接加在关键点和直线上的，在计算过程中，默认下是自动转化过接到相应mesh所得到的节点或单元上的，这个不用担心 esize,0.002,0??smrt,2??这个命令使得网格比较细，如果确实分析有必要这么细那就这样，如果没有必要，建议降低，而且可以试着局部加细，不要统统都esize为0.002，其他不要紧的地方可以给的粗一点liusl101 hekie ，谢谢了！ 我是试了一下将精度降低，但网格划分还是较慢。还有我考虑了是不是中间内轮廓内两个较小的体没有同外部的体相耦合，这是一个
