Hi Rob,

Thanks for your response.

Over the years the below journal TUI steps had been working for me with 2020R2 version. There's no h5 extension

And get results like below

With the 2022R2 version i did as shown below 

The simulation runs but no output files.

I tried again to adjust like below 

Its the same thing. The simulations runs but no output files.

I have never experience this issue when i was using .cas and .dat files only.

Please i need help in case  i missed some lines.
