Known bugs in version 11.0b
- Disabled line contact relationships were being used to determine the extent of the coupling between lines when using either the solve coupled systems line statics step 2 policy or the include coupled objects modal analysis option. This meant that the degrees of freedom of a larger group of model objects than was strictly required may have been included as part of a single coupled analysis, even when the system could have been decomposed into two or more independent subsystems. This just affected the grouping of the degrees of freedom when performing the analysis; the results of any coupled analysis would still have been valid.
- Line contact relationships in which the protected or splined lines had not been assigned were simply being ignored during the calculation. Such relationships are invalid and should have been brought to the attention of the user via an error message.
- Attempting to use the analytic catenary solver to determine the shape of a line in reset state could sometimes lead to an unexpected error if the line was neutrally buoyant.
- Morison element drag diameters were not being converted correctly when the model units system was changed. For instance, if drag diameters were entered in SI units, and the model units system was subsequently changed to US units, then the Morison element drag diameters were not being correctly converted from metres to feet.
- The PD 8010 Young’s modulus was not being converted correctly when the model units system was changed. This data is used in the PD 8010 torsion, load combinations and bending strain checks.
- The SHEAR7 bending stress curvature load factor was not handled correctly when using non-SI units systems. When OrcaFlex creates the SHEAR7 data file, it must convert to the units system used by SHEAR7. When using non-SI units, SHEAR7 requires stress values to be given in kpf/in2 (ksi), but previous versions of OrcaFlex were incorrectly converting to kpf/ft2.
- An access violation error was raised if the OrcFxAPI function C_GetVarID was called for an OrcaFlex object that does not provide any results, e.g. type objects.
These bugs will be fixed in version 11.0c.
