I have understood pretty well about the definition of parameters except in recorders material 1,5, 17 as written below.
"recorder Element -ele 1 -time -file stress1 -dT $dT material 1 stress
recorder Element -ele 1 -time -file strain1 -dT $dT material 1 strain
recorder Element -ele 1 -time -file stress5 -dT $dT material 5 stress
recorder Element -ele 1 -time -file strain5 -dT $dT material 5 strain
recorder Element -ele 1 -time -file stress17 -dT $dT material 17 stress
recorder Element -ele 1 -time -file strain17 -dT $dT material 17 strain"
Can anyone explain what does it mean? and why we have written 3 materials even though in code there is only one nDmaterial defined?
If my understanding is right, the number after the "material" indicates the Gaussian point at which the stresses are calculated. I am not aware of any element with 17 Gauss points. Usually in 2D problems and with quadrilateral elements, we have four Gauss point. Therefore, you recorders will be:
recorder Element -ele 1 -time -file stress1.out -dT $dT material 1 stress
recorder Element -ele 1 -time -file strain1.out -dT $dT material 1 strain
recorder Element -ele 1 -time -file stress2.out -dT $dT material 2 stress
recorder Element -ele 1 -time -file strain2.out -dT $dT material 2 strain
recorder Element -ele 1 -time -file stress3.out -dT $dT material 3 stress
recorder Element -ele 1 -time -file strain3.out -dT $dT material 3 strain
recorder Element -ele 1 -time -file stress4.out -dT $dT material 4 stress
recorder Element -ele 1 -time -file strain4.out -dT $dT material 4 strain
