[Libmesh-users] Regarding subdomain restricted variable updating

2013-11-14 Thread Vikram Garg
Hey all, I had a question regarding the subdomain restricted variables functionality. My understanding is that the user specifies specific subdomains and regions where certain variables are defined and are active, and the library then assembles the systems accordingly. If the subdomains

CondesdEigenSystem removes Dirichlet rows and columns from the matrix using create_submatrix. Hence I don't think you'd have to worry about what calling DofMap::constrain_element_matrix does to those entires since they'll be removed anyway. David On 11/14/2013 10:19 AM, Manav Bhatia wrote: >

Thanks John for the quick answer, Let me explain; what I would like to do is to create an EquationSystems and then create a system under it with a (several) variable(s) and fill the solution vector from the ExodusII file. Is this possible and how can I do it? Thanks again, Ata On Thu, Nov 14,

2013-11-14 Thread Manav Bhatia
Hi, Should the DofMap::constrain_element_matrix be called before assembly of element matrix for the CondensedEigenSystem? I suspect that the answer is "yes" for AMR, but what if DirichletBoundaries are defined for the system? The idea for the CondensedEigenSystem would be to create a redu
