question about SampleMeshManager about librom HOT 2 CLOSED

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.
