+ | ===== Results ===== | ||
+ | For each integration point: | ||
+ | * Stresses (see material law) | ||
+ | * State variable: | ||
+ | * Q(1→NVMAX): see material law | ||
+ | * Q(NVMAX+1): $e_{xM}$ | ||
+ | * Q(NVMAX+2): $e_{yM}$ | ||
+ | * Q(NVMAX+3): $e_{zM}$ | ||
+ | * Q(NVMAX+4): $e_{xF}$ | ||
+ | * Q(NVMAX+5): $e_{yF}$ | ||
+ | * Q(NVMAX+6): $e_{zF}$ | ||
+ | * If there are contact elements (see law): | ||
+ | * Stresses of the contact element | ||
+ | * State variables of the contact elements | ||
+ | State variables of the additional solid element (not printable in the .out file): | ||
+ | * Local coordinates | ||
+ | * Rotation matrix to change to the local frame | ||
