Q: In FLUENT: how can you replace an existing mesh with another similar one - is there an efficient way to retain the non-geometric parameters and models while substituting the mesh?


A: The older FLUENT text user interface (tui) "file/reread-grid" functionality has been replaced in version 6.2 by the "grid/modify/replace-zone" functionality. this was part of more detailed grid activation, deactivation, deletion by zones capability.

In version 12, something very close to the older functionality for replacing the entire grid was added back under the file menu in the text user interface (tui) as:

file/replace-mesh filename

and in version 13, the same tui command is also available as:

mesh/replace filename

"mesh" is the new name for the tui "grid" menu, from version 12. however, FLUENT recognizes the "grid" name of this menu as well. across all versions, the other way to do this is write a boundary conditions file from a set-up fluent case by:

file/write-bc filename

then, read a grid, and read back the bcs file as follows:

file/read-bc filename

note that "write-bc" and "read-bc" also do not appear anymore from version 12 on. the new name for this functionality is "read-settings" and "write-settings". however, here too old names are recognized. of course, when reading a bc (settings) file, in addition to materials and settings, all mesh threads with same names will be reassigned same conditions.
