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,

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

Aborting OpenFAST.[/code]
And I am getting this -
Running ElastoDyn.
Nodal outputs section of ElastoDyn input file not found or improperly formatted.
Running AeroDyn.
Nodal output section of AeroDyn input file not found or improperly formatted.
What might be solution for this?
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.
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?
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.
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.
So getting this “Nodal outputs section of ElastoDyn input file not found or improperly formatted” won’t affect the simulation in anyway right?
I mean wind speed, wave height, wave period,etc.
I am still facing this error

Correct, the “nodal output” warning will not effect the simulation results; you can ignore the warning.
The wind speed is specified in the InflowWind model. The wave height and wave period are specified in the HydroDyn input file.
Regarding the error about “Line2 element…length” can you clarify where version of OpenFAST you are running and which OpenFAST input file you are running (please share links if possible)?
I used 5MW_OC3Mnpl_DLL_WTurb_WavesIrr model for simulation.
But, when I run 5MW_OC4Jckt_DLL_WTurb_WavesIrr_MGrowth model, it shows terminated normally (attached). Does that mean it is working fine and if so, is .out file the output which we need?
If above one is correct, what might be the reason of error for 5MW_OC3Mnpl_DLL_WTurb_WavesIrr model?
