General data: Results

Spectral density fundamental frequency

Only available for time domain analyses. Defines the fundamental (minimum) frequency for spectral density graphs derived from time histories. The default value is usually quite reasonable, but smaller values may sometimes be required to achieve good resolution of the spectral form.

Sample interval for time history synthesis

Only available for frequency domain analyses. Defines the sample interval for time histories synthesised from frequency domain processes.

Wave drift load component seed

Only available for frequency domain analyses at low frequency solution frequencies. Defines the seed used in a random number generator to assign phases when synthesising replays and time histories from frequency domain processes associated with the wave drift load process.

Wall clock time, CPU time

These two output values, found on the properties report, can also be obtained through the OrcaFlex automation interface. Both report the time taken to perform the dynamic simulation.

• Wall clock time measures the real time, in seconds, that elapsed between the start and finish of the simulation.
• CPU time measures the total CPU time, in seconds, summed over all processors in the system.

The results can be extracted using the OrcaFlex post-processing spreadsheet. Use the Get Data command with object name General and data name WallClockTime or CPUTime.

From the Python or MATLAB interfaces use the following code:

WallClockTime = model.general.WallClockTime
CPUTime = model.general.CPUTime

From C or C++ you should call C_GetDataDouble passing the handle of the general data object and data name "WallClockTime" or "CPUTime".

Log file location(s)

This value, also found on the properties report, can be obtained with the automation techniques described above using the name LogFileLocation. This value is the location of any log files used by an OrcaFlex simulation.

Results

For general information on selecting and producing results, see the producing results topic.

Time

The simulation time.

Ramp

The ramping factor.

Implicit solver iteration count

The number of iterations used by the implicit integration scheme to solve the dynamic equilibrium equations.

Implicit solver time step

The time step used by the implicit integration scheme. This is most useful when you are using a variable time step.
