The mainplate is welded from the upper and the lower part. There is no contact between coverplate and mainplate. The binding is formed by the welding at the corner and the node 6 is the only shared node between mainplate,coverplate and weld. What I would like to do is to double or copy the nodes 275,296,312,281,299,315 and then assign one of these nodes to cover plate and another one to mainplate. Therefore, I can get it stress results at that place. How I can assign a node to an element? I am sendding the commands of my modeling, thanks finish /clear /PREP7 *SET,MPLENGTH,600 *SET,MPTHICK,12 *SET,CPLENGTH,100 *SET,CPTHICK,12 *SET,TLENGTH,3 *SET,WELDANGLE,145 *AFUN,DEG *SET,HLEGLENGTH,ABS(TLENGTH/SIN(180-WELDANGLE)) *SET,VLEGLENGTH,HLEGLENGTH*TAN(180-WELDANGLE) K,1 ,((MPLENGTH/2)+(CPLENGTH/2)),MPTHICK,0 K,2 ,((MPLENGTH/2)+(CPLENGTH/2)+HLEGLENGTH),MPTHICK,0 K,3 ,((MPLENGTH/2)+(CPLENGTH/2)),(MPTHICK+VLEGLENGTH),0 LSTR, 1, 2 LSTR, 3, 2 LSTR, 3, 1 AL,1,2,3 K,4 ,((MPLENGTH/2)+(CPLENGTH/2)),0,0 K,5 ,((MPLENGTH/2)+(CPLENGTH/2)+HLEGLENGTH),0,0 K,6 ,((MPLENGTH/2)+(CPLENGTH/2)),(-VLEGLENGTH),0 LSTR, 4, 5 LSTR, 5, 6 LSTR, 6, 4 AL,4,5,6 K,7 ,((MPLENGTH/2)-((CPLENGTH/2)+HLEGLENGTH)),MPTHICK,0 K,8 ,((MPLENGTH/2)-(CPLENGTH/2)),MPTHICK,0 K,9 ,((MPLENGTH/2)-(CPLENGTH/2)),(MPTHICK+VLEGLENGTH),0 LSTR, 7, 8 LSTR, 8, 9 LSTR, 9, 7 AL,7,8,9 K,10 ,((MPLENGTH/2)-((CPLENGTH/2)+HLEGLENGTH)),0,0 K,11,((MPLENGTH/2)-(CPLENGTH/2)),0,0 K,12,((MPLENGTH/2)-(CPLENGTH/2)),(-VLEGLENGTH),0 LSTR, 10, 11 LSTR, 11, 12 LSTR, 12, 10 AL,10,11,12 BLC4,0,0,MPLENGTH,MPTHICK BLC4,((MPLENGTH/2)-(CPLENGTH/2)),MPTHICK,CPLENGTH,CPTHICK BLC4,((MPLENGTH/2)-(CPLENGTH/2)),(-CPTHICK),CPLENGTH,CPTHICK !
