Fluent report definitoin error

      Hello


      I have faced a strange error when using report definitions and output parameters.


      For example, when the calculation is finished, the mass weighted average of temperature gives very wrong value, as can be seen from the picture. Once I redefine it, have to change the variable from temperature to some other thing, and change it back to temperature, then it gives correct value. It is also reporting another "random" value to the workbench through output parameter. The error is not only happening to temperature, but also for some other energy variables, such as entropy.


      The case was perfectly converged, and all the variable field looks reasonable. Only the report definition values are wrong. What could be reason behind it?


      Kind Regards

      Sometimes, it appears to be able to compute correctly in Fluent, however it transfers different values to workbench through output parameters. Please see the above pictures.

      Thanks for the reply. I am using 2019R2, and this version is installed in university computers that I am working on. So, it will be difficult to switch to 2020R1 in a short time for me. Is this a bug? Any method I can use to go around this issue?


      Kind Regards

      Hello,


      Could you please attempt to reproduce this issue on a simple problem such as flow through a simiple pipe and verify if you are seeing this issue?


      Thank you.


      Best Regards,
