Upcoming in OrcaFlex 10.2: Line feeding

For the final post in our series on upcoming developments for version 10.2, we look at line feeding. Line feeding allows line to be dynamically fed into, or out of, the active model. OrcaFlex 10.2 is very nearly ready to be released and we expect this to happen in the next fortnight. In the meantime, […]

Upcoming in OrcaFlex 10.2: Text labels on 3D views

It’s been a little while since we posted in our series on upcoming developments for version 10.2. We’ve been busy finishing off development for the release, and hosting our annual series of user group meetings. OrcaFlex 10.2 is very nearly ready to be released and we expect this to happen in the next fortnight. In […]

We have just released a minor upgrade to OrcaFlex, version 10.1e. This minor upgrade fixes the following bugs: In earlier OrcaFlex versions, when importing vessel type data from AQWA, both difference frequency QTFs and sum frequency QTFs were conjugated upon import. After feedback from users, we now have a more complete understanding of the AQWA QTF […]

Upcoming in OrcaFlex 10.2: New line clearance results

Continuing our series of posts on upcoming developments for version 10.2, we consider a number of enhancements to the line clearance results. Historically, OrcaFlex has offered results reporting the clearance between lines. These results report the shortest distance, in 3D space, between lines. Results are available for clearance between centrelines or between contact surfaces. Some […]

Upcoming in OrcaFlex 10.2: Support and constraint release

Continuing our series of posts on upcoming developments for version 10.2, we consider a couple of enhancements to the support and constraint objects. OrcaFlex objects can be connected to each other, so that the connected objects move together. In addition, certain types of connections can be released at defined points in the simulation. For example, […]

Upcoming in OrcaFlex 10.2: Vessels and 3D buoys can be slave objects

Continuing our series of posts on upcoming developments for version 10.2, let’s now look at a further relaxation of the rules relating to object connectivity. In version 10.0 we made it possible to connect lines to lines and to form chains of connections, e.g. 6D buoy1 is connected to 6D buoy2, which in turn is […]

Upcoming in OrcaFlex 10.2: Coupled object modal analysis

Continuing our series of posts on upcoming developments for version 10.2, we now move to an important enhancement to modal analysis. This development has aspects in common with another new feature, line statics policy, which we have discussed in an earlier post. OrcaFlex modal analysis calculates modes for individual lines or for the entire system. […]
