The base file was being overwritten with the output. YAML fatigue files that use BaseFile were not being processed correctly in batch mode. Loading a static state simulation file could result in an invalid floating point operation if a summary results window was active.Д«inary data files did not store information on whether constraint and turbine objects were locked in the model browser. Stiffener attachments protecting the ends of lines could make an unwanted Rayleigh damping contribution to the line end connection load if torsion is not included and the protected line end also has finite end connection stiffness. external function, post calculation actions, user defined results, etc.) would sometimes fail for virtual Python environments. fem files was failing (reporting an invalid node number error) for some valid files that contain triangular elements (ELPTYP=25).Д®mbedded Python execution (e.g. If the target model already contains type objects with the same names, then a decision must be made: use the data from the clipboard, or use data already in the target model? OrcaFlex is meant to ask the user to make this decision, but since 10.3a the mechanism to ask the user has been broken and the program always opts to use the data already in the target model. For instance, if a line is copied from one model to another, any line types that the line uses are also copied. When copying objects between models via the clipboard, OrcaFlex copies associated type objects. msh files has been added for wire frame drawing import, and shaded graphics model import. Python post calculation actions which use user defined results previously failed with an unexpected error.

Slam force coefficients were not being saved to text data files for line types of the equivalent line category. This has been observed when starting a batch run, but the issue could also occur when using the API to open multiple data files simultaneously.

The errors are thrown by the slug flow drawing code so a simple workaround is to disable slug flow drawing for each line that uses the slug flow contents method.ДЄ multithreading bug could lead to program crashes when opening multiple data files simultaneously. Invalid floating point operation errors could be shown when performing calculations for models with lines using the slug flow contents method and that also specify the frequency domain dynamics solution method. This will most significantly affect vessels for which the static equilibrium has a large yaw disparity relative to the reset heading. However, the vesselвЂ™s heading after the static equilibrium has been calculated is more appropriate. Previously the vesselвЂ™s heading in reset state was used to perform this calculation. When solving in the frequency domain at low frequency, the wave drift load process relies on interpolating the QTF data on wave direction relative to vessel heading. To trigger the bug, the constraint had to begin moving during simulation by use of the out-frame release stage data or release condition, and have only fixed degrees of freedom initially.

Users could encounter an error with message вЂњAttempt to read a variable that has not been loggedвЂќ when requesting velocity or acceleration results for a shape object that was (directly or indirectly) held by a constraint. Opening the Morison element type data form could result in grid index out of range error messages for models containing a large number of Morison element types. 1 file refers to waves by period or by angular frequency.

The import process will now attempt to determine whether the. This assumption could be false, and the imported data would then be associated with the wrong period or frequency. The WAMIT output file presenting multibody added mass and damping data for import was assumed to always refer to waves by period. The removal of this contribution from the manoeuvring load is done by the first term of the load component equations presented in the theory. Part of the contribution to vessel inertia load from added mass was included in the simulation twice. Vessel manoeuvring load has been changed to exclude a contribution that was previously double-counted. OrcaFlex also has the unique capability in its class to be used as a library, allowing a host of automation possibilities and ready integration into 3 rd party software. OrcaFlex is the worldвЂ™s leading package for the dynamic analysis of offshore marine systems, renowned for its breadth of technical capability and user friendliness.
