As previously announced, due to the Coronavirus pandemic, we are running our OrcaFlex user group meetings as virtual webinars. Now that version 11.1 has been released we can announce that these webinars will take place in the middle of March.

These webinars will cover all the new features introduced in version 11.1 of OrcaFlex and OrcaWave. There is a lot of content to cover. Because long online meetings can be quite demanding, we have decided to split the content into three separate webinars. We will deliver each one of these three webinars twice in the same day, so hopefully most users can 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.

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 know that no webinar can be as engaging as an in-person meeting, but we will do our best to make it interesting. We look forward to catching up with our regular user group attendees, and hopefully some first timers too!

OrcaFlex restart analysis

This webinar will cover the new restart analysis feature. Supporting functionality including change tracking and enhanced analysis data will also be introduced.

OrcaWave new features

This webinar will introduce the new features in OrcaWave, our diffraction analysis program.

OrcaFlex new features (apart from restart analysis)

Having covered restart analysis separately, this webinar introduces all the other new features in OrcaFlex 11.1.

We are very pleased to announce the release of OrcaFlex version 11.1. The software was finalised and built on 12^th February. We originally planned to release 11.1 in Q4 of 2020. However, we delayed the release in order to complete the restart analysis development. We plan to make the next release in the traditional Q4 slot, later this year.

All clients with up-to-date MUS contracts will receive, in the week starting 22^nd February, an e-mail with instructions on how to download the new version.

Version 11.1 introduces much new functionality, including:

• Restart analysis, variation models, and change tracking
• Turbine pre-bend
• Turbine range graphs
• Hysteretic and externally calculated axial and torsional line stiffness
• Performance improvements for wave time history analysis
• Wire frame drawings specified by panels
• Embedded Python scripts as an alternative to external files
• OrcaWave intermediate results
• OrcaWave target roll damping
• OrcaWave performance improvements

These are the most significant developments, in our opinion. As always there are more enhancements that are not listed here. All new features are fully documented in the what’s new topics:

We have just released a minor upgrade to OrcaFlex, version 11.0g. Version 11.0g fixes a number of bugs in both OrcaFlex and OrcaWave. Full details of the changes are described in the documentation:

• OrcaFlex
• OrcaWave

We recommend that all users of 11.0 upgrade to 11.0g.

A patch to upgrade from earlier 11.0 releases can be downloaded here. The full installation program can also be downloaded from your Orcina download page. Please contact us if you do not have the link to your Orcina download page.

We aim to release a major OrcaFlex update in Q4 of each year. This year we are not going to achieve this goal, and version 11.1 will now be released early in 2021. We hope and expect that we will be able to do this in January or February.

The most significant new feature in 11.1 will be restart analysis. We are excited to be adding restarts, and development is very well advanced and progressing smoothly. However, it is such a broad feature, and impacts almost all existing functionality in the program, that development and testing has taken a long time. We considered releasing 11.1 without restarts in Q4 2020 to fit in with our schedule goals. We decided that it is preferable to delay the release a couple of months and ensure that restart analysis is included.

As well as delaying the OrcaFlex release, we have decided also to push the user group meetings into the new year. As previously announced these will be virtual because of the pandemic. Our intention is that these meetings will run around the same time as the OrcaFlex release.
