Dear Dr. Jonkman,
I encounter a strange problem. I am running Test13 and want to output the local force and moments at 50% tower height and blade span. and the output file has showed that these local output are invalid showed below:
I guess there is something wrong with the NTwGages and NBlGages in ElastoDyn input file. But I still cannot figure it out as I think my settings seems to be all right.I have attached my ElastoDyn input file for your reference. Sorry I dont know how to upload the txt file.
