1. For brick elements, the stresses are output in the elemental (corotational) coordinate system for /PROP/TYPE14 (SOLID) elements, and in the orthotropic material coordinate system for /PROP/TYPE6 (SOL_ORTH) elements if corotational formulation is used. For all other cases the stresses are output in the global coordinate system.
2. Using /ANIM/BRICK/ORTHDIR with properties 6, 21, and 22 will output 3 real values of angle $\psi ,\theta ,\text{and}\hspace{0.17em}\varphi$ in unit [deg]. Defining rotation matrix $R$ , to go from global reference system to orthotropic reference system:
   • Rotation matrices
   • A rotation of $\psi$ radians about the x-axis is defined as:(1)
     $$R_x\left(\psi \right)=\left[\begin{array}{ccc}1& 0& 0\\ 0& \text{cos}\psi & -\text{sin}\psi \\ 0& \text{sin}\psi & \text{cos}\psi \end{array}\right]$$
   • Similarly, a rotation of $\theta$ radians about the y-axis is defined as:(2)
     $$R_y\left(\theta \right)=\left[\begin{array}{ccc}\text{cos}\theta & 0& \text{sin}\theta \\ 0& 1& 0\\ -\text{sin}\theta & 0& \text{cos}\theta \end{array}\right]$$
   • Finally, a rotation of $\varphi$ radians about the z-axis is defined as:(3)
     $$R_z\left(\varphi \right)=\left[\begin{array}{ccc}\text{cos}\varphi & -\text{sin}\varphi & 0\\ \text{sin}\varphi & \text{cos}\varphi & 0\\ 0& 0& 1\end{array}\right]$$
   • The angles $\psi ,\theta ,\text{and}\hspace{0.17em}\varphi$ are the Euler angles:(4)
     $$R=R_z\left(\varphi \right)R_y\left(\theta \right)R_x\left(\psi \right)$$
     (5)
     $$R=\left[\begin{array}{ccc}\text{cos}\theta \text{cos}\varphi & \text{sin}\psi \text{sin}\theta \text{cos}\varphi -\text{cos}\psi \text{sin}\varphi & \text{cos}\psi \text{sin}\theta \text{cos}\varphi +\text{sin}\psi \text{sin}\varphi \\ \text{cos}\theta \text{sin}\varphi & \text{sin}\psi \text{sin}\theta \text{sin}\varphi +\text{cos}\psi \text{cos}\varphi & \text{cos}\psi \text{sin}\theta \text{sin}\varphi -\text{sin}\psi \text{cos}\varphi \\ -\text{sin}\theta & \text{sin}\psi \text{cos}\theta & \text{cos}\psi \text{cos}\theta \end{array}\right]$$
3. The option SIGEQ is available with Eltyp = SHELL or BRICK only (/ANIM/SHELL/SIGEQ). Each material law, in Radioss has its own yield criterion to calculate the equivalent stress. For some it is von Mises; for others, it is Hill or Barlat or something else. For any non-von Mises criterion, the corresponded equivalent stress (or criterion) is computed within all the integration points of the element. Therefore, the output field /ANIM/BRICK/SIGEQ is computed as a mean value over all integration points.
4. For brick elements, the stresses are output in the elemental (corotational) coordinate system for /PROP/SOLID elements, and in the orthotropic material coordinate system for /PROP/SOL_ORTH elements, when corotational formulation is used. For all other cases the stresses are output in the global coordinate system.
5. The option /ANIM/ELEM/SIGX is only applied for shell elements. For brick elements, /ANIM/BRICK/TENS must be used.
6. User variables are only available for shell and brick elements. When an integration point is not explicitly described, returned integration point means the integration point is superior; computed as [(number of integration points in thickness + 1) / 2]. The result is then rounded up to the superior value.
   • Example:

     For two integration points in thickness, second integration point from bottom (top of thickness) is returned.

     For three integration points in thickness, second integration point from bottom (middle one) is returned.

     For four integration points in thickness, third integration point from bottom is returned.

7. The Schlieren contour value is computed using $\xi =e^{-c\nabla \rho }$ . Radioss outputs $\xi$ using c=1. The constant $c$ can be updated using HyperView by creating a derived result ${\xi }^{c_{user}}$ .
8. For solid elements using LAW51, it is possible to display results for a given sub-material number (1 to 4) using:
   • /ANIM/ELEM/LAW51/ALL: results for all sub-material, or
     • /ANIM/ELEM/LAW51/1: results for sub-material 1
     • /ANIM/ELEM/LAW51/2: results for sub-material 2
     • /ANIM/ELEM/LAW51/3: results for sub-material 3
     • /ANIM/ELEM/LAW51/4: results for sub-material 4
     In this case, the following options can be displayed per phase:

     • /ANIM/ELEM/P
     • /ANIM/ELEM/DENS
     • /ANIM/ELEM/ENER
     • /ANIM/ELEM/SSP
     • /ANIM/ELEM/EPSP
     • /ANIM/ELEM/TEMP
     • /ANIM/ELEM/VOLU
     • /ANIM/MASS
9. For quad or brick elements, /ANIM/ELEM/DAM1, /DAM2, and /DAM3 are available for material LAW24. These values are the principal values of the damage (values in the local cracking skew).
10. Element time step is displayed in the animation only if elementary time step is computed for this element by Radioss. If nodal time step used (/DT/NODA) in the calculation, element time step is not displayed in the animation.
11. Option DAMG is only used with coupled damage models (/MAT/LAW72 or /FAIL/GURSON) to output damage over integration points. The damage variable is normalized by its critical value.
    • For /MAT/LAW72(6)
      $$D_{mg}=\frac{D}{D_C}$$
    • For /FAIL/GURSON(7)
      $$D_{mg}=\frac{f_t}{f_F}$$
12. If /NONLOCAL/MAT option is activated, it is possible to output the regularized non-local plastic strain and its rate.
