Attempt to access unallocated Phase1::VolumeFractionLevel1 storage in cells
 
Hi,

I intend to run a simulation aimed to capture cavitation. I previously achieved the intake wake and then ran a non-cavitating simulation. The non-cavitating simulation is just for a one-phase fluid i.e. H2O. No multiphase defined. After obtaining this results. I initiated the VOF and multiphase which includes liquid and gas.

I keep on getting this error when I do this:

" Attempt to access unallocated Phase1::VolumeFractionLevel1 storage in cells in Fluid
Processor: 105
Recoverability: Non-recoverable "

Does anyone have an idea on how to fix this?

Initialize your case


The error is self explanatory but if that doesn't work you're going to have to describe better the events leading up to error.

Thanks for your response. I already initialized it. Before this error, I have run 6000 steady state iterations. During this, the domain was just liquid (single phase).
Then, I ran unsteady simulations summing over 50,000 iterations.
After which, I switched to a dual phased fluid i.e. water and vapour. Some other models were included. These are a multiphase interaction model and the VOF.
