Hi Keyur,

Thank you for the prompt reply. Yes I can open it in Fluen Meshing. The problem is that I can read the mesh using Fluent, perform computation, then save dat and cas. However, if I close the case and want to reopen the case using Fluent, it returns the error I mentioned in the original post. 

The "check" and "check the quality" reports are as follows. Could you please see if there is anything I can do? I do not want to read the mesh every time and then read the journal file to recover the case setup... Thank you very much. 

Domain extents.

Done.

 

Minimum Orthogonal Quality = 3.00263e-01

(To improve Orthogonal quality , use "Inverse Orthogonal Quality",

where Inverse Orthogonal Quality = 1 - Orthogonal Quality)

 

 

Maximum Aspect Ratio = 1.62759e+01
