OrcaFlex 11.2d released

We have just released a minor upgrade to OrcaFlex, version 11.2d. Version 11.2d fixes a number of bugs. Full details of the changes are described in the documentation. Note that there are no changes to OrcaWave in this release.

We recommend that all users of 11.2 upgrade to 11.2d.

To upgrade to OrcaFlex 11.2d from any previous version, download the install program from your company’s Orcina software download page. A link to this page was sent to your software administration contact when we released 11.2a. If you do not have access to this page, please contact us.

32 bit operating system end of support in OrcaFlex

Microsoft stopped offering 32 bit versions of Windows 10 to computer manufacturers in early 2020, and Windows 11 is only available for 64 bit systems. OrcaFlex and OrcaWave require 64 bit processes for efficient performance and from our own experience we cannot remember the last time we came across a user running on a 32 bit version of the operating system.

Accordingly, version 11.3, scheduled for release towards the end of 2022, will be the final version of OrcaFlex which can be installed on a 32 bit version of Windows. Future releases of OrcaFlex, after 11.3, will require 64 bit versions of Windows.

Note that we will continue supplying both 32 and 64 bit versions of the program executable files, but we strongly recommend that you use the 64 bit versions. We are making this change because it is becoming ever harder to test our installation package on 32 bit systems. Limiting support to 64 bit systems will also simplify the development of the installation package.

Distributed OrcaFlex 6.2a released

We have just released Distributed OrcaFlex 6.2a which you can download from the Distributed OrcaFlex web page.

This is a relatively minor update containing the following changes:

  • Previously, when submitting jobs, you specified whether you wanted both statics and dynamics to be performed, or just statics. Starting in OrcaFlex 11.1 the input data specifies whether statics and/or dynamics are to be performed. Because this setting has been moved into the model data, it is no longer possible to make this choice when submitting jobs in Distributed OrcaFlex. However, it is sometimes useful to be able to skip dynamics even if it is enabled in the input data. A new skip dynamics option has been added to the submit job dialog which mirrors the identically named option on the OrcaFlex batch processing form.
  • The console program (dofcmd.exe) can now list jobs in both yaml and csv format. Previously only csv format was available.
  • Jobs with post calculation actions would sometimes be restarted by the server if the post calculation action spent too long processing without sending a progress update. This release fixes that issue, but also requires that the Python OrcFxAPI module is updated.

Note that if you wish to take advantage of the improved handling of long-running post calculation actions, then you will need to update your Python OrcFxAPI module. This would happen normally by an OrcaFlex update, and the next minor release (11.2d) will include the required changes. In the meantime if you need to update then you can do so from the PyPI repository using this command:

pip install –ignore-installed –no-deps OrcFxAPI

Python 2 end of support in OrcaFlex

Support for Python 2 ended at the start of 2020. OrcaFlex has continued to support Python 2 in the releases that we have made since then, but future releases of OrcaFlex will not support Python 2. This means that 11.2 will be the final version of OrcaFlex with support for Python 2.

This means that scripts using the Python interface to OrcaFlex, external functions, post-calculation actions and user-defined results will all require Python 3 from the next release of OrcaFlex. The minimum supported version of Python will be Python 3.6.

OrcaFlex 11.2c released

We have just released a minor upgrade to OrcaFlex, version 11.2c. Version 11.2c fixes a number of bugs. Full details of the changes are described in the documentation. Note that there are no changes to OrcaWave in this release.

We recommend that all users of 11.2 upgrade to 11.2c.

To upgrade to OrcaFlex 11.2c from any previous version, download the install program from your company’s Orcina software download page. A link to this page was sent to your software administration contact when we released 11.2a. If you do not have access to this page, please contact us.

OrcaFlex 11.2b released

We have just released a minor upgrade to OrcaFlex, version 11.2b. Version 11.2b introduces some minor new functionality and fixes a number of bugs. Full details of the changes are described in the documentation:

We recommend that all users of 11.2 upgrade to 11.2b.
