Engine Keyword Generate H3D contour output results for /SPRING spring elements.



#optional next line(s) that lists the parts to save results for

part_ID1... part_IDN


# Spring element timestep
# Force and moment output for only parts IDs 356 and 293.
356 293


Field Contents SI Unit Example
Keyword3 Output types. 3  
part_IDN Optional list of part IDs for which results will be output.  


  1. The syntax /H3D/ELEM/Keyword3 is also valid.
  2. When PART IDs are listed after the /H3D/SPRING line the specified results will only be output for those parts.
  3. The scalar output is defined in the following tables.
    Table 1. Scalar Output
    Keyword3 Description
    AMS Elements using AMS timestep due to /DT/CST_AMS.
    DAM1, DAM2, DAM3 Damage in direction 1, 2 or 3. 4
    DT Element timestep.
    ENER Specific energy density (internal energy divided by the element mass).
    EPSP Plastic strain.
    F1, F2, F3 Force in local coordinate system.
    Force in X direction
    Force in Y direction
    Force in Z direction
    FORC All forces and moments in local coordinate system.

    F1, F2, F3, M11, M21, M31, M12, M22, M32.

    M11, M21, M31, M12, M22, M32 Moment in local coordinate system.
    Moment in X at node 1
    Moment in Y at node 1
    Moment in Z at node 1
    Moment in X at node 2
    Moment in Y at node 2
    Moment in Z at node 2
    MASS Element mass
    OFF Element status.
    Where the result output is:
    = -1
    Element is not active (it is defined in an activated rigid body).
    = 0
    Deleted element.
    Between 0 and 1
    Under failure process.
    = 1
    Active element.
  4. Damage in springs is defined as the maximum value between time 0 and the current time of the displacement versus failure displacement ratio: (1)
    D A M = max t ( δ ( t ) δ max )

    For TYPE13 (/PROP/SPR_BEAM) springs, damage direction 1 is traction/compression, 2 and 3 are shear y and z.

    For TYPE8 (/PROP/SPR_GENE) springs, damage directions 1, 2 and 3 are, respectively x, y and z.
