** ERROR 308306 ** Number of cells per volume value is not specified or not appropriate.
Please check the value and run the analysis again.
If you choose to use the Constant nucleation density model, which is the default selection, you are required to enter the number of cells per volume. This value is then used by the solver to calculate the various results. If you select the Fitted Classical Nucleation Model, this entry box disappears, but other data is required if you do not use the default foaming gas.
