I applied temperature T1 on L1 and T2=-(L1T1)\/L2 on line number 2 in order to have constant total length. After solving the code, I measured the strain in line 1 and 2 (ETABLE,starin, LEPTH, 1) and then calculated the final length. On the other hand, I measured the final length using LL1=sqrt(((nx(1)-(nx(4)+ux(4)))**2)+((ny(1)-(ny(4)+uy(4)))**2)) and LL2=sqrt(((nx(2)-(nx(4)+ux(4)))**2)+((ny(2)-(ny(4)+uy(4)))**2)) command lines.
