Detailed Description

template<typename Trafo_>
class FEAT::Assembly::DomainAssembler< Trafo_ >

Domain Integral Assembler class template.

This class implements a multi-threaded domain assembler, which is capable of executing domain assembly jobs.

After you have constructed the domain assembler object, there are still a few steps left that have to be performed before you can assemble a assembly job by the domain assembler:

Optional: You can choose a specific threading strategy by calling the set_threading_strategy member function or you can just stick with the default automatic strategy that is preselected.
Optional: You can choose the maximum number of desired worker threads for the multi-threaded assembly by calling the set_max_worker_threads member function. Skipping this step always results in single-threaded assembly.
If you want to assemble on the whole domain, i.e. on all elements of the mesh (which is the usual case), all you have to do as a final mandatory step is to call the compile_all_elements() member function.
If you want to assemble on a subset of the domain, you have to add all elements to the domain assembler by either adding them individually using the add_element() function or by adding them as mesh-parts using the add_mesh_part() member function. Once all elements have been added, you have to call the compile() member function.

Note: Each domain assembler object is tied to the trafo object that is has been constructed on, i.e. if you have several different trafo objects (such as in a multigrid scenario) then you also need several domain assembler objects – one for each trafo object. Also, a domain assembler always assembles over the elements of its trafo, so all FE spaces used in the assembly have to be defined on the same trafo object as the domain assembler.

Attention: Please be aware that the setup of a DomainAssembler object is a rather expensive operation, because the assembler has to perform a lot of internal initialization including an analysis of the element adjacency pattern as well as applying graph coloring/layering algorithms, which (in general) may have super-linear runtime. Therefore you should always hang on to a DomainAssembler object once it has been created and avoid re-creation of several DomainAssembler objects that could have been avoided by saving a previously created DomainAssembler object.
