Dynamic Storage

The following results may be stored from dynamic analysis:

1. Displacements

  • Nodal displacement time series in the global coordinate system.

2. Force response

The following is available for the specified elements:

3. Sum force response

The following is available for the specified elements:

  • Time series of the sum of material + damping + inertial axial force for specified elements.

4. Curvature response

The following is available for the specified elements:

  • Time series of curvature for specified elements

5. Envelope curves

Key results for each line e. g. displacement, element force and curvature. Useful for getting an overview of the response of the structure.

Different amounts of statistics may be selected:

  • Minimum, maximum and standard deviation

  • Minimum, maximum, standard deviation, mean value and mean-crossing periods

  • Minimum, maximum, standard deviation, mean value, mean-crossing periods, skewness and kurtosis

6. Stress storage

The following is available for the specified elements:

  • Calculate stresses for circular cross-sections based on element forces and moments and specified cross-sectional properties. The calculation is similar to the Pipe Stress operation in the SIMA Port Processor.

7. Wave kinematics

  • Wave kinematics at the kinematics nodes may be stored for irregular analysis. Pre-generated or updated kinematics depending om the choice of Kinematics position in Irregular Analysis.

8. Turbine response

Results may be stored for selected wind turbines. A description of the stored results may be found in Wind Turbine → Wind turbine results.

9. Turbine blade response

The following is available for the specified turbine blade elements:

10. Support vessel results

  • Support forces are reported for all supernodes attached to the specified support vessel or SIMO body.

    • Forces may be stored in either the global coordinate system or in the support vessel or body coordinate system.

    • If more than one line is connected to a supernode, the resultant forces acting on the vessel or body are also reported.

11. Hydrodynamic loads

Time series of hydrodynamic loads may be stored for selected elements.

  • The added mass load contribution is not included in the stored loads. The total (excepting added mass) hydrodynamic loads are available for all hydrodynamic load models.

  • For the time domain VIV load model, the relative fluid velocity and the individual load terms are also available

12. Bottom contact

The following results may be stored:

  • Bottom contact forces for selected elements

  • Touch down point location and seafloor contact for TDP (touch down point) element and an additional selected number elements next to the TDP element.

See illustrations in Arclength to TDP and Storage of sea floor forces

13. Body results

The following can be stored

  • Forces from slender system acting on the body

    • Forces may be stored in either the global coordinate system or in the body system.

  • Body results

Available for bodies only

14. 3D visualization

  • Dynamic response may be stores visualization. Two formats are available:

    • SIMA 3D graphics (Default): The .ldat file may also be viewed with the SimVis program.

    • VTF format: The .vtf file may then be visualized in programs such as Ceetron GLView and SESAM Xtract.

Time series must be stored in the binary format of they are to be explored or post-processed in SIMA.

15. Wasim results export

Export results from the simulation to files that can be read by Wasim.

  • Wave components

  • Motion, velocity and acceleration for selected body

  • Point forces

Available for bodies only
