Based on your question I think you are expecting that the sampling of DOFs is performed in SampleMeshManager
. Am I right? The SampleMeshManager
is used to construct a FiniteElementSpace
containing the sampled variables determined with for instance the DEIM. It does not sample itself.
I think the answer on issue #187 will give clarity.

@JacobLotz Thanks, your answer makes it more clear. After looking at the code, DEIM/S_OPT/GNAT determines the sample_dofs
and then the SampleMeshManager
builds a FiniteElementSpace
. As for my question about the error, I guess the error is implicitly determined by the number for basis vectors/reduced space dimension for V', 'X', 'H'
. DEIM/S_OPT/GNAT will determine the best dofs to sample, given the basis vectors and basis size. There is no direct parameter to set the error of the ROM and then determine a sample mesh.
