Coupling MAP++ to OpenFAST causes Segmentation Fault #238

Closed dwalia closed 5 years ago

dwalia commented 5 years ago

I have an OpenFAST simulation set up using MoorDyn, which runs without problems. However, when replacing MoorDyn by MAP++ I run into a Segmentation fault error.

I need to run a OpenFAST simulation by use of MAP++ because I need to generate the mooring stiffness matrix, for setting up BModes.

I was running OpenFAST 2.0.0 in Linux when inicially running into this error. I rebuilt OpenFAST and installed v2.1.0 because I thought that there might be a link to error #227. This didn´ t solve the problem. I also downloaded the windows executable for OpenFAST v2.0.0 and ran the same simulation in Windows 10 with ending up with the same error.

Dear @dwalia ,

I can't comment on the actual error right now, but if you using MAP++ in OpenFAST only to derive the 6x6 stiffness matrix associated with the mooring system for use in BModes, you can use the Python wrapper for standalone MAP++ to derive this, as discussed in the following topic on our forum: https://wind.nrel.gov/forum/wind/viewtopic.php?f=4&t=1123&p=10717.

Best regards,

dwalia commented 5 years ago

Dear @jjonkman ,

thank you very much for pointing out that possible workaround. I will have a look on that. I will also try to rerun the simulation by use of OpenFAST 1.0.0 as well as running a simulation provided by NREL for older (FAST 8.16) versions which use MAP++

My bad, I had a bug in my input files. Closes: #238
