thanks for your advice,Martin .! 
 I think the input files , topog.box and windx.sin_y  matched the total gird size in size.h ,but I don't understand the following "Then you have to make sure that you use the approprate "precision" for your input files. If the model expects double precision (readBinaryPrec = 64), a single precision  field will be too small (by a factor of 2) "   , 
 I want to know where I can find the precision , need I change  something  in  the file ? 
at last , what  does it mean by "a clean (unmodified) experiment and then change one thing at a time."     can you tell me something  in detail ?
 I am eager for your help ,thank you  so much !!
