Dear Jason,

Thanks for your reply.

I am getting following error after changing the path.

How do I need compile for .dll file?

And do I need to do anything to work on Aerodyn and hydrodyn or just changing the path is enough?

Thanks,
Satish J

Dear Satish,

Again, the path to the DISCON.DLL could be incorrect. Or you are running a 64-bit OpenFAST executable and trying to use a 32-bit DISCON.DLL.

Did you compile OpenFAST yourself or download the precompiled binaries for Windows? Included with the precompiled binaries for Windows are DISCON.DLLs compiled for both 32- and 64-bits.

Dear Jason,

Thanks for your reply.

I downloaded binaries and i used the same dll file which resulted this error.

And I am getting this -

What might be solution for this?

Dear Satish,

Regarding the first error, did you change r-test model in some way, e.g., move joints around in HydroDyn?

Regarding the second error, I'd have to see your ElastoDyn and AeroDyn input files to comment. Again, I would recommend enabling the Echo option to debug problems in the input file processing.

Hi Jason,

Thanks for your reply.

I haven't done any changes in r-test. what might be reason for this error?

I have attached Aerodyn and Elastodyn input files.

Thanks,
Satish J

Dear Satish,

I don't see any problems in the nodal output formatting. What is printed to the echo ([*]*.ech) files?

Can you attach this echo file?

Dear Satish,

You've attached the echo file for the OpenFAST primary input file, but the formatting problems are in the ElastoDyn and AeroDyn input files. Can you attach the echo files for those?

Dear Satish,

I don't see that ElastoDyn had any trouble interpreting the nodal outputs, so, I'm not sure what is triggering this warning. And you attached the HydoDyn echo file, not AeroDyn, so, I can't check if there is a formatting problem in the AeroDyn input file. Regardless, the warning about the nodal outputs don't seem to be preventing the simulation from running.

Dear Jason,

Thanks for your reply.

Sorry! I have attached Aerodyn echo file. What might be the solution?

And is it possible to change the inputs such as environmental parameter?

Thanks,
Satish J

Dear Satish,

I don't see that AeroDyn has any problem interpreting the nodal outputs either. But again, this warning doesn't seem to be preventing OpenFAST from running. So, there need to be any solution. Is OpenFAST running now running as expected? Or do you have errors preventing OpenFAST from running.

What do you mean by "environmental parameters".

Dear Satish,

I asked Andy Platt regarding the "nodal output" warnings, and here is his response:

I will change those to Info instead of warning.

When we added the node based outputs, we kept the input files for each module backwards compatible. The node outputs is a second output section following the standard output section. So the warning/info is just to let the user know that this section of the input file does not exist and that they won't get node based outputs. This was added to ElastoDyn (blade nodes only), BeamDyn, and AD15, so all three modules may report this info at initialization.
