- the snGradTransformDiag() is used in this type of code:
```
if constexpr (!is_rotational_vectorspace_v<Type>)
{
// Rotational-invariant type
return tmp<Field<Type>>::New(this->size(), pTraits<Type>::one);
}
else
{
return pTraits<Type>::one - snGradTransformDiag();
}
```
This implies that a rotational-invariant form should return 0
and not 1 like the pow(..., 0) does.
This is a backstop for any code that may inadvertently hit it,
but also allows the possibility of having integer indicator fields
without upsetting the compiler.
STYLE: doTransform() logic now uses is_rotational_vectorspace

Description
|
|
This boundary condition enables processor communication across patches.
|
|
|
|
Usage
|
|
Example of the boundary condition specification:
