求大神帮助划分下网格，模型是交流电通过电极施加到长方体熔体的一个侧面上，各个面的电磁场分布肯定不一样，有电极的一面跟连接的侧面电磁场强度大，要如何划分网格，下面是一段运行程序，网格划分不好，请大师帮忙划下，谢谢了。 /prep7 /units,mks LOCAL,11,1,0,0,0 WPCSYS,,11 et,1,231 !1-熔体 et,2,231 !2-电极 mp,murx,1,1 mp,rsvx,1,1.8E-8 mp,murx,2,1 mp,rsvx,2,1.0E-7 block,0,0.04,0,0.12,0,0.04 cyl4,0.02,0.03,0,0,0.005,360,-0.03 cyl4,0.02,0.08,0,0,0.005,360,-0.03 vglue,all numcmp,all vsel,s,volu,,1 vatt,2,,2,11 vsel,s,volu,,2,3 vatt,1,,1,11 allsel,all aesize,8,0.002 aesize,1,0.001 allsel,all mshape,1,3d vmesh,all allsel,all SAVE asel,s,area,,6 nsla cp,1,volt,all allsel,all asel,s,area,,10 nsla cp,2,volt,all allsel,all FINISH /solu antyp,trans |

不知道你想要什么样的网格，试着对模型做了一些切割，然后划分 MAP 网格，相应命令流如下 (到划分好网格为止，其余你自己改吧)： fini /clear /filname,xiaoxu /prep7 /units,mks LOCAL,11,1,0,0,0 WPCSYS,,11 et,1,231 !1-熔体 et,2,231 !2-电极 mp,murx,1,1 mp,rsvx,1,1.8E-8 mp,murx,2,1 mp,rsvx,2,1.0E-7 block,0,0.04,0,0.12,0,0.04 cyl4,0.02,0.03,0,0,0.005,360,-0.03 cyl4,0.02,0.08,0,0,0.005,360,-0.03 vglue,all numcmp,all vsel,s,volu,,1 vatt,2,,2,11 vsel,s,volu,,2,3 vatt,1,,1,11 allsel,all aesize,8,0.002 aesize,1,0.001 allsel,all /AUTO,1 !* LPLOT SAVE, !* FLST,2,2,5,ORDE,2 FITEM,2,7 FITEM,2,11 VDRAG,P51X, , , , , , 10 !* FLST,2,3,6,ORDE,2 FITEM,2,3 FITEM,2,-5 VOVLAP,P51X !* !* LPLOT !* FLST,2,2,3,ORDE,2 FITEM,2,29 FITEM,2,31 KWPAVE,P51X !* wpro,,90.000000, !* FLST,2,3,6,ORDE,3 FITEM,2,2 FITEM,2,5 FITEM,2,-6 VSBW,P51X !* LPLOT !* FLST,2,2,3,ORDE,2 FITEM,2,25 FITEM,2,27 KWPAVE,P51X !* FLST,2,3,6,ORDE,3 FITEM,2,1 FITEM,2,4 FITEM,2,11 VSBW,P51X !* LPLOT wpro,,,90.000000 !* FLST,2,11,6,ORDE,6 FITEM,2,2 FITEM,2,-3 FITEM,2,5 FITEM,2,-10 FITEM,2,12 FITEM,2,-14 VSBW,P51X !* LPLOT !* /VIEW,1,,,-1 /ANG,1 /REP,FAST !* csys,0 !* FLST,2,4,3 FITEM,2,39 FITEM,2,40 FITEM,2,5 FITEM,2,2 A,P51X VSBA, 29, 1 !* FLST,2,4,3 FITEM,2,51 FITEM,2,52 FITEM,2,38 FITEM,2,37 A,P51X !* VSBA, 28, 1 !* FLST,2,4,3 FITEM,2,35 FITEM,2,36 FITEM,2,7 FITEM,2,3 A,P51X !* VSBA, 31, 24 !* FLST,2,4,3 FITEM,2,33 FITEM,2,34 FITEM,2,54 FITEM,2,53 A,P51X !* VSBA, 30, 24 !* FLST,2,4,3 FITEM,2,37 FITEM,2,38 FITEM,2,34 FITEM,2,33 A,P51X !* FLST,2,2,6,ORDE,2 FITEM,2,32 FITEM,2,-33 VSBA,P51X, 48 !* FLST,2,4,3 FITEM,2,39 FITEM,2,40 FITEM,2,36 FITEM,2,35 A,P51X !* FLST,2,2,6,ORDE,2 FITEM,2,14 FITEM,2,28 VSBA,P51X, 48 !* NUMMRG,KP, , , ,LOW numcmp,all !* KWPAVE, 55 !* !* wpro,,,90.000000 !* FLST,2,30,6,ORDE,2 FITEM,2,1 FITEM,2,-30 VSBW,P51X !* LPLOT !* /VIEW,1,,,-1 /ANG,1 /REP,FAST !* !* 以下设置体的属性，小圆柱为 材料 1；其余为 材料 2，不知是否正确 FLST,5,24,6,ORDE,4 FITEM,5,1 FITEM,5,-18 FITEM,5,29 FITEM,5,-34 CM,_Y,VOLU VSEL, , , ,P51X CM,_Y1,VOLU CMSEL,S,_Y !* CMSEL,S,_Y1 VATT, 1, , 1, 0 CMSEL,S,_Y CMDELE,_Y CMDELE,_Y1 !* FLST,5,8,6,ORDE,2 FITEM,5,19 FITEM,5,-26 CM,_Y,VOLU VSEL, , , ,P51X CM,_Y1,VOLU CMSEL,S,_Y !* CMSEL,S,_Y1 VATT, 2, , 1, 0 CMSEL,S,_Y CMDELE,_Y CMDELE,_Y1 !* !* 以下设置单元尺寸或线段分段数，准备进行 MAP 无关划分 LESIZE,ALL,0.008, , , ,1, , ,1, !* FLST,5,16,4,ORDE,12 FITEM,5,13 FITEM,5,-16 FITEM,5,23 FITEM,5,-26 FITEM,5,93 FITEM,5,-94 FITEM,5,97 FITEM,5,-98 FITEM,5,100 FITEM,5,-101 FITEM,5,104 FITEM,5,-105 CM,_Y,LINE LSEL, , , ,P51X CM,_Y1,LINE CMSEL,,_Y !* LESIZE,_Y1, , ,2, , , , ,1 !* FLST,5,16,4,ORDE,10 FITEM,5,27 FITEM,5,-30 FITEM,5,41 FITEM,5,44 FITEM,5,46 FITEM,5,48 FITEM,5,84 FITEM,5,-87 FITEM,5,89 FITEM,5,-92 CM,_Y,LINE LSEL, , , ,P51X CM,_Y1,LINE CMSEL,,_Y !* LESIZE,_Y1, , ,2, , , , ,1 !* FLST,5,16,4,ORDE,10 FITEM,5,17 FITEM,5,-20 FITEM,5,33 FITEM,5,36 FITEM,5,38 FITEM,5,40 FITEM,5,62 FITEM,5,-65 FITEM,5,80 FITEM,5,-83 CM,_Y,LINE LSEL, , , ,P51X CM,_Y1,LINE CMSEL,,_Y !* LESIZE,_Y1, , ,2, , , , ,1 !* !* MSHAPE,0,3d MSHKEY,1 VMESH,all MSHKEY,0 !* numcmp,all !* !* SAVE |
