about Cart3d and moving body
 

I'm using the Cart3d to solve a CFD problem about moving body and I want to integrate forward in time with 6DOF and modify the freestream conditions in time too. Someone told me that I could do this by automatically editing the input.cntl file which controls the flow solver freestream conditions. But I don't how to do this in this software.

Would you be kind enough to tell me how to automatically editing the input.cntl in time in the software?

Thank you very much for your help!
