【求助】对流和生热率同时加，生热率加不上
|
|||
|
我做的是平板对接激光焊温度场模拟。加载过程中，先在长方体的五个面（SURF152表面效应单元）上加了对流，又在体（SOLID70单元）上加了生热率。但是结果只有一个未加对流载荷的面上加上了生热率，其余五个面温度是室温。百思不得其解，请高手指教。以下是我加的对流和生热率 ET,3,SURF152 KEYOPT,3,4,1 KEYOPT,3,5,1 KEYOPT,3,6,0 KEYOPT,3,8,1 KEYOPT,3,9,1 R,3,1,5.67E-14 TYPE,3 REAL,3 MAT,3 MPTEMP,,,,,,,, MPTEMP,1,20,300,600,750,900,1200 MPTEMP,7,1500,1800,2000 MP,HF,MAT,1,6,50,120,180,200,250 MP,HF,MAT,7,378,700,850 ALLSEL ASEL,S,LOC,X,0,0 CM,AREA1,AREA SFA,AREA1,,CONV,-3,20 ALLSEL ASEL,S,LOC,X,PLATE_LEN,PLATE_LEN CM,AREA2,AREA SFA,AREA2,,CONV,-3,20 ALLSEL ASEL,S,LOC,Y,PLATE_WID,PLATE_WID CM,AREA3,AREA SFA,AREA3,,CONV,-3,20 ALLSEL ASEL,S,LOC,Z,0,0 CM,AREA4,AREA SFA,AREA4,,CONV,-3,20 ALLSEL ASEL,S,LOC,Z,PLATE_HEI,PLATE_HEI CM,AREA5,AREA SFA,AREA5,,CONV,-3,20 ALLSEL SAVE LO_COORD=0 RECY_NODE=1 LOAD_STEP=PLATE_LEN/WELD_GRID *DO,CALCURECY,1,LOAD_STEP,1 LO_COORD=CALCURECY*WELD_GRID LOCAL,20,1,LO_COORD,0,0,,,,1,1 ALLSEL,ALL NSEL,ALL NROTAT,ALL ALLSEL,ALL NSEL,S,LOC,Z,0,0 NSEL,R,LOC,X,0,1 ESLN,S ESEL,R,TYPE,,2 CM,N01,ELEM SAVE ALLSEL,ALL NSEL,S,LOC,Z,0.5,0.5 NSEL,R,LOC,X,0,0.7 ESLN,S ESEL,R,TYPE,,2 CM,N02,ELEM SAVE ALLSEL,ALL NSEL,S,LOC,Z,1,1 NSEL,R,LOC,X,0,0.4 ESLN,S ESEL,R,TYPE,,2 CM,N03,ELEM SAVE ALLSEL,ALL CMSEL,S,N01,ELEM CMSEL,A,N02,ELEM CMSEL,A,N03,ELEM CM,N_%RECY_NODE%,ELEM SAVE CSDELE,20,,, SAVE CSYS,0 ALLSEL,ALL NSEL,ALL NROTAT,ALL ALLSEL,ALL RECY_NODE=RECY_NODE+1 *ENDDO /SOLU ANTYPE,TRANS,NEW TRNOPT,FULL TIMINT,ON TINTP,,,,1 LUMPM,0 LNSRCH,1 NROPT,FULL,, EQSLV,ICCG,1.0E-5 NEQIT,50 AUTOTS,1 KBC,1 OUTRES,BASIC,LAST NSUBST,5,10,1 TUNIF,25 SAVE ALLSEL RECY_NODE=1 *DO,CALCURECY,1,LOAD_STEP,1 CSYS,0 ALLSEL,ALL CMSEL,S,N_%RECY_NODE%,ELEM BFE,ALL,HGEN,,QVOLUME TIME,CALCURECY*WELDGDTM ALLSEL,ALL SOLVE SAVE ALLSEL,ALL CMSEL,S,N_%RECY_NODE%,ELEM BFEDELE,ALL,HGEN ALLSEL SAVE RECY_NODE=RECY_NODE+1 *ENDDO 错误日志显示： Both solid model and finite element model boundary conditions have been applied to this model. As solid loads are transferred to the nodes or elements, they can overwrite directly applied loads. 还请大侠们指教 |
