Initializes a scalar field from a geometric body.
Currently supported are Sphere, Ellipsoid and Box (= AABB)
Examples:
<InitializerUID> {
initialFill : drop;
someArbitraryId {
shape sphere;
add; // add to the current value in the field
value 1.0;
midpoint < 3,4,5>;
radius 4;
id 0; // If given a vector of scalar fields, which one of them to operate on.
// Should be zero (the default value) if given a scalar field directly.
}
object2 {
shape box;
add;
value -3.14;
min <1,2,3>;
max <3,4,5>;
}
object3_ellipse {
set; // overwrite the current value in the field
value 0;
shape ellipsoid;
midpoint < 3,4,2>;
axis1 <1,0,0>;
axis2 <0,1,0>;
radii <1,1,4>;
}
}

Interface implementation for Initializer - sets a body on a scalar field with options from configuration file.
Implements walberla::geometry::initializer::Initializer.
| void walberla::geometry::initializer::ScalarFieldFromBody< Field_T >::init | ( | const Body & | body, |
| math::FunctionParser & | parser, | ||
| bool | addOrSet, | ||
| std::vector< BlockDataID >::size_type | id = 0 ) |
Sets a body on the scalar field.
| body | The body object - has to implement either overlapFraction(...), or contains(...) see BodyOverlapFunctions for detailed body concept |
| parser | A function parser which will have the variables x,y,z bound before it is evaluated |
| addOrSet | If true, the value is added to scalar field If false, the value is set on the scalar field. |
| id | If operating on a vector of fields, which field to treat. Zero otherwise. |
Supported bodies are Sphere, Ellipsoid, AABB. To add a new supported body implement concept defined in BodyOverlapFunctions.h, and add an explicit template instantiation in ScalarFieldFromBody.cpp for the new body.

| Value_T | value, | ||
| bool | addOrSet, | ||
| std::vector< BlockDataID >::size_type | id = 0 ) |
Sets a body on the scalar field.
| body | The body object - has to implement either overlapFraction(...), or contains(...) see BodyOverlapFunctions for detailed body concept |
| value | The value to set on the matched cells in the field. |
| addOrSet | If true, the value is added to scalar field If false, the value is set on the scalar field. |
