Hi,

I am a bit confused on the use of internalField versus setFieldsDict. If I specify the internalField (whether uniform or a vector list), do I still need a setFieldsdDict?

In my particular case, I am running mesh refinement for a transient case, so the initial internalField (for the subsequent mesh refinements) is defined using mapFields and the previous coarser solution. Do I need to define a setFieldsDict as well for this finer run?

Thanks

internalField contains the values of the field for each cell. Alternatively, you can specify uniform values.

If you want to start your simulation with non-trivial initial conditions, then you can use:

• setFields to specify non-uniform values
• mapFields to use computed values from another case

Using setFields or mapFields is optional, so you only need the [map|set]FieldsDict file when you use corresponding pre-processing tool.


If you directly write your non-uniform values into the internalField list, then you do not need to use any pre-processing tool. However, this list has as many entries as the mesh has cells.
