I would say, that the most recommended method at the moment in Icepak is
HD mesher. But in a simple geometry like this, the mesh should be almost
the same no mattet what the methdod is. Just make sure, that you have
same amount of elements on each fin and between the fins, when comparing
methods and models. At least in the packed project this was not the
case. Set all max and min parameters to same values as well. And does
the source object have approximately the same amoint of elements with
each method?
You can make comparison easier, if you set object parameters for
meshing. In mesh control panel, just select "Object params" and then
edit. Icepak tries to mesh the model according your settings.
