Query Regarding DAResidual Registration in DAFoam

[lnhang0618]

Dear Prof. He,
I've come across an intriguing detail that I'd like to discuss. Specifically, I noticed that the DAResidualPtr_ pointer in DASolver gets redirected in createAdjointIncompressible.H by the following code:

daResidualPtr_.reset(DAResidual::New(solverName, mesh, daOptionPtr_(), daModelPtr_(), daIndexPtr_()));

Being acquainted with OpenFOAM's Run-Time Selection (RTS) mechanism, I sought out the registration of DASimpleFoam using:
addToRunTimeSelectionTable(DAResidual, DASimpleFoam, dictionary);

However, to my surprise, I couldn't locate this. Instead, I stumbled upon:

addToRunTimeSelectionTable(DAResidual, DAResidualSimpleFoam, dictionary);

This has led to some confusion on my end. Given the apparent absence of direct registration of DASimpleFoam within the DAResidual base class, I'm curious about the connection between DASimpleFoam and DAResidualSimpleFoam.

Warm regards,

I believe I have resolved this issue. Within the RTS (Run Time Selection) mechanism, registration is not done using the filename like DAResidualSimpleFoam.C, but rather through the typeName found in DAResidualSimpleFoam.H. In this instance, TypeName("DASimpleFoam") indicates that the sub-table's index name in the DAResidual hash table is DASimpleFoam.
