MeshTags associate values with mesh entities.
The entity index (local to process) identifies the entity. MeshTags is a sparse data storage class; it allows tags to be associated with an arbitrary subset of mesh entities. An entity can have only one associated tag.
Type |
Create a MeshTag from entities of given dimension on a mesh.
[in] | mesh | The mesh on which the tags are associated |
[in] | dim | Topological dimension of mesh entities to tag |
[in] | indices | std::vector<std::int32> of sorted and unique entity indices (indices local to the process) |
[in] | values | std::vector<T> of values for each index in indices. The size must be equal to the size of indices . |
|
inline |
Find all entities with a given tag value.
[in] | value | The value |
