Using curvilinear constraints to impose motion

OrcaFlex has two objects whose motion can be imposed rather than calculated: The vessel object through displacement RAOs, harmonic motion, time history or externally calculated motion. The constraint object (added in version 10.1) through motion time histories in the constraint’s imposed displacement mode. In addition to these more well-known methods of imposing motion, the constraint […]

OrcaFlex 10.2b released

We have just released a minor upgrade to OrcaFlex, version 10.2b. This minor upgrade fixes the following bugs: The following features may not have worked correctly for lines that have inactive parts: line profile graphs; fatigue analysis; splined lines in line contact relationships; penetrating lines that are around splined lines in a line contact relationships. The […]

Distributed OrcaFlex 6.0c released

This is a minor update release which fixes a few bugs that have come to light since the 6.0b release. The new release is available here: Distributed OrcaFlex 6.0c The changes include: Bug fix: Sometimes, in the event of an error, the DOF Server would produce a cascade of error report files that caused the […]

OrcaFlex 10.2 released

It’s been over a year since OrcaFlex 10.1 was released, which means it is time for the 2017 major release, version 10.2. The software was finalised and built on 24th November. All clients with up-to-date MUS contracts should receive the new version by early December. We have been blogging regularly through the development process and […]

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 […]

OrcaFlex 10.1e released

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 […]
