Re: Access violation error for 180deg wind

Dear Jason, Ok, then I was effectively simulating very large yaw angle misalignment with a large restoring moment applied at t = 0 (which was not my intention). Apparently the 90 deg propagation didn't immediately throw an error, but the same faulty simulation set-up was used. Your guidance to the Y...

Re: Access violation error for 180deg wind

Hi Jason, Thanks for your help. I indeed tried already small variations around the 180 deg, but these also did not run. I extended this range of angle to check at what point the simulations starts to fail. I changed the following settings: - Turned off waves/current in order to isolate the wind cont...

Access violation error for 180deg wind

Dear Jason, I am trying to run openFAST in which the waves and wind field have a propagation direction of 180 deg. At the same time, I am also running the exact same model, but for directions of both 0 deg and -90 deg (wave and wind are colinear). The latter two directions are working just fine, but...

Re: HydroDyn - Full QTF with multiple directions

Thanks Jason. I did come across this post, but since it was a few years old and didn't see this topic among the open issues on GitHub, I expected it to be resolved in V2.2.0.

I may have to spend some effort again in compiling FAST myself then.

Best regards

HydroDyn - Full QTF with multiple directions

Dear Jason, I am trying to get a simulation to run with a full QTF obtained from WAMIT. However, I continue to struggle, as HydroDyn will not accept my .12d input file. I am aware that HydroDyn expect all direction pairs to be populated and I have updated my input file accordingly. Still, I keep get...

Re: openFAST v2.2.0 binearies

Thanks for the response Jason. I am not using the 64bit executable together with a 32bit controller library; I use the 32bit executable. However, openFAST throws an error message (in attachment) suggesting that my controller is compiled in 64bit (which it is not). If I run exactly the same simulatio...

Re: openFAST v2.2.0 binearies

Hi Rafael, I am trying to run openFAST 2.2.0 (32bit) but are running into trouble due to my controller library being compiled in 32bit. Apparently, v2.2.0 expects the controller DISCON.dll to be compiled in 64 bit? The exact same simulation is running fine in V2.1.0. Is there something to be done fr...

Re: Wind loads on floater body

Dear Jason, Thank you for clearing this up and apologies for my late reply (due to Xmas holiday). I sincerely hope this feature can be added in a future release, as its an important part of total loading for quite a few of the floating wind concepts out there. The implementation could be quite simpl...

Wind loads on floater body

Hi Jason & others, I am currently modeling a floating wind concept in which the floater has a non-negligible area above the still water surface. Therefore, it will attract significant wind loads, especially in the cut-out range and above. It is however unclear to me if there is any option of pro...

Re: openFAST v2.2.0 binearies

Hi Rafael, Thanks for your prompt reply. I understand the problem, but was this also not the case for previous releases (I had to install those Intel libraries also to get 2.1.0 working)? Speaking entirely for myself of course, but first having to installing the intel libraries is for me only a mino...

openFAST v2.2.0 binearies

Dear NREL team, I noticed that for the latest openFAST release (2.2.0) there are presently no pre-compiled binaries available on GitHub, as was the case for previous releases. Is there any reason for this? I would like to use the latest release, as there are some bugfixes which are helpful, but I ne...

Re: openFAST - release versus self compilation

Dear Jason, Thanks for the reply. Perhaps another benefit of compiling the code is to be able to go into debug mode in order to retrieve the source of some error? Anyway, perhaps it would be an idea to highlight the option of simply downloading the latest release in the user documentation (instead o...

openFAST - release versus self compilation

Dear all, I am very eager to use openFAST, but I have a few questions regarding the use and compilation of openFAST. Although I have an engineering background, I do not have a lot of experience with software development and compiling code. My questions may therefore seem silly, but perhaps others wi...
