Dear Sir,

Thank you for your reply. 

I have checked the case with Fluent 2023R1 after saving the case and data file in .cas.h5 and .dat.h5 format respectively. But, I am facing a similar issue after running the case at some non-zero time step.

I am sure I am doing a very small error while setting up the case. Please let me know you need any detail to solve this problem.
