Need help with Error
 
Hallo,
I changes my Simulation from steady to implicit unsteady and now I get always this Error Message:

An internal error has occurred. Please contract your support representative with details.

Attempt to access unallocated VolumeFractionLevel1 storage in cells in Region1.


Can anybody help me to fix this error?

Thank you very much!!

Which version are u using? Did u initialized the steady state solution before running unsteady? Try both, start unsteady with a clear solution and try with initilaizing the steady one.

Did you freeze the momentum equation before starting the transient?
I got this error when I switched to the unsteady simulation keeping the momentum equation deactivated.
I solved the problem running 1 iteration with all the equation active.
