| The stresses in the 3D solid elements are computed at the centroid of the element and are referred to in global axes. The stresses are shown in the following figure: | The stresses in the 3D solid elements are computed at the centroid of the element and are referred to in global axes.

| In addition to the user-requested response, ACS SASSI [[sassi:MOTION]] may also output other components of the response if calculation of these components is necessary in order to determine the requested response. For example, in order to output maximum octahedral shear stress for 3D solid elements, all six components of stress must be computed. Therefore, ACS SASSI MOTION also outputs the maximum response of these components. However, the corresponding time histories are not to be saved on File12 unless they are specifically requested by the user. | In addition to the user-requested response, ACS SASSI [[sassi:MOTION]] may also output other components of the response if calculation of these components is necessary in order to determine the requested response.
