transf.in
 

Hi H.c
I read your comment thanks for your care. i can't find transf.in file in my simulation directory to add those lines. why i dont have this files? in your idea what should i do? I am using F3D 9. Thank you so much:):)

you need to create a new text file in the simulation directory, put those lines into the text file and rename it to "transf.in". make sure the extension "txt" is removed.

Hi H.c
with you'r help i can do what i want. Thank you so much buddy:):)
