We have just released Distributed OrcaFlex 7.0a which you can download from the Distributed OrcaFlex page.

This is a major update containing the following changes:

• DOF can now handle simulation restarts. Restart parents are identified in the DOF Viewer when submitting a batch of jobs and the DOF Server will ensure that the dependency chain is run in the correct order if the ‘Respect restart sequence’ check box is selected when submitting jobs. When adding restart child models, you can automatically include the restart parents if you check the ‘Include restart parents’ check box. The child restart models must be ‘.yml’ text data files.
• The DOF Viewer can display full details for a selected job in a pop-up window from the context menu. Client machine details can be viewed in a pop-up from the context menu in the DOF Viewer OrcaFlex Clients tab. The DOF Server settings can be seen in a pop-up window by double-clicking the DOF Viewer status bar.
• The speed of handling of the job status and progress messages in the DOF Server has been improved.
• The list of DOF Clients kept by the DOF Server is now saved in structured text format (yaml) file. This can be edited to give a DOF Client an alias name for display in the DOF Viewer rather than its machine name.
• Bug Fix: If a client disconnected during communication with the DOF Server this would cause an error in the server.
• Bug Fix: A client could fail to provide a MAC address to the DOF Server which meant that the ‘Wake on LAN’ feature would not work.
• Bug Fix: If a DOF Client was disabled whilst running jobs, these jobs were given a ‘moving’ status but could block later scheduling to that DOF Client if other client machines were busy.

We have just released a minor upgrade to OrcaFlex, version 11.3b. Version 11.3b introduces some minor new functionality and fixes a number of bugs. Full details of the changes are described in the documentation:

Following the release of OrcaFlex 11.3, we can now announce our OrcaFlex 11.3 user group meetings. Once again, we are running these as virtual webinars.

These webinars will cover all the new features introduced in version 11.3 of OrcaFlex and OrcaWave. We will split the content into two separate webinars, one for OrcaFlex and one for turbines and OrcaWave. Each webinar will be delivered twice in the same day to give users in different time zones the opportunity to attend.

We anticipate that each webinar will be around one hour in duration, and attendees will be able to ask questions. Recordings of the webinars will be available on our website shortly after they have taken place.

We are running the webinars over Zoom. You will need to register for whichever webinars you wish to attend, using the links below. Zoom webinars can be attended using the Zoom client, or directly from the browser if you do not have the Zoom client.

We look forward to catching up with our regular user group attendees, and hopefully some first timers too!
