import an Ansys mesh in Abaqus (.dat format)

Hi, I'm trying to import an Ansys mesh in Abaqus. The file I have is in .dat format. I have done: import  ->   model (selecting the dat format). Is it correct? Because then I have the following "import nastran message": errors and/or warnings were found when translating and importing the mode. The imported Abaqus/CAE model may be missing features. I don't understand if the procedure I used is wrong or if there's some mistake in the dat file. 

attached the log file I get 

Thanks
