What does the warning message FICOUV - Error detected by operating system (29) mean?

Yann_Le_Floch

This warning message can appear when loading a project:

“FICOUV => Error detected by operating system (29)
FICOUV => No such file or directory \...\SOLVE_FLU_60.EFL ... end loading project”

It means that some project files are missing (for instance GEOM_FLU_.EFL; MESH_FLU_.EFL; SOLVE_FLU_.EFL). It occurs when some files are deleted from the .FLU folder and not in Flux. For instance, if you want to delete the results and the mesh, you should open the project in Flux and then delete the results and the mesh.
