hello everyone, I used the adams2013 to simulate the test14 with normal operation,I used the test14.adm,test14.acf and adams2013.dll.But when I use the adams to simulate the lineration using the test14\_lin.acf,the error happened: ![error.jpg](https://europe1.discourse-cdn.com/nrel/original/1X/4c002a7c0987ca77526f31bc130af268eea5b651.jpeg) I don’t know why. I have another question about compile the adams2013.dll use the BladeDLLinTERFERCE.F90 to simulate the 5mw turbine.Is it same to others? HOPE YOUR HELP BEST REGARD Ruiliang.Wang ---

Dear Ruiliang, These warnings are related to the trouble with the numerical integrator in MSC.ADAMS. I suggest you follow the guidance given in the warning message. We’ve had success with (3), but you have to ensure that the solution remains accurate. MSC technical support can provide further guidance. The controller DLL for the NREL 5-MW turbine does not require a customization to the Bladed DLL interface; the BladedDLLInterface.f90 source file supplied with the FAST archives can be used directly. Best regards,
