Dear Paul, Thanks for your quick response. My “solution-…txt” file is created from other language (Julia), just an array. I want to use deal ii to get mesh, then solve the minimization problem in Julia language on the mesh, and then do mesh refinement according to the solution by using deal ii again. I read the block_write() just now, It says that “This is done in a binary mode, so the output is neither readable by humans nor (probably) by other computers using a different operating system or number format.”, so I think it is not what I want.
