My recollection from Aqwa-Flow is it prints the X Y and Z components of velocity, in amplitude and phase form, for each wave frequency component,...
Morison elements in Aqwa are not the appropriate implementation. You create diffracting elements and solve the radiation and diffraction problem...
As I understand it, a big part of the reason morison elements were introduced into Aqwa was so you don't need to resolve the radiation and...
Ray, I trust I answered your question in e-mail. If not, I can elaborate here. For those reading, you cannot have morison elements as...
If you use the PMST option, which means Print Mooring Section Tensions, then by default it prints the fairlead tension and the anchor tension....
Cable dynamics, i.e. simulation of non-linear moorings, is failing. Try adjusting the length of the mooring line. Slack moorings are not...
There is no limitation on the movements of the vessel if hydrodynamic interaction is turned off.
I would really need to look at the workspace to answer your questions. I have some ideas of what's going on as I've encountered many of the same...
Hi Inventus, Our OpenFOAM model is really only of academic value. It works, in the sense that things move, and the fluid moves, and it spits out...
The time domain vessel motions include the linearized radiation and diffraction forces. As far as I know there is no way to get the diffracted...
I don't know how to do that in Workbench. In GS/batch mode use the ZRWS option (deck 18) before specifying the nodes for printing.
Understandable. I meant using CFD for finding equivalent (more accurate) damping factors in the areas of interaction where viscous flows can't be...
Yeah, I'd have to dig up my notes, the external lid is originally defined for structure to structure interaction. I think it's a little fuzzy...
You'll probably have to edit the data file outside of workbench and replace the QPPL/TPPL with QPPL DIFF/TPPL DIFF to make them diffracting...
Post the Aqwa workspace (if you're still having trouble). The negative damping issue is probably due to irregular frequencies, and/too few...
0.8mm was the high end, the low end was 0.2mm so half of that seems right. Also, I did mis-read your first post but some pictures I've seen show...
All, I apologize for this latent reply, I hope it doesn't come across as ungracious, I do appreciate the responses. ruysg, the specifications...
Hi, thanks for the reply. The specific issues being looked at are corrosion and abrasion and how they impact fatigue life of FOWT moorings,...
Hi, I am looking for material related to the effects of corrosion and abrasion for floating offshore wind turbine mooring systems. Strictly...
Add one, it'll stop those fictitious waves inside the spar.
