Re: [Libmesh-users] Basis Functions at Dirichlet Boundary

Sounds like you want to use FEMSystem for Navier-Stokes with a non-homogeneous DirichletBoundary. This is done in fem_system_ex1, so I suggest you look there. The boundary conditions are specified via subclasses of FunctionBase, e.g. see class BdyFunction : public FunctionBase in naviersystem.C

Re: [Libmesh-users] Basis Functions at Dirichlet Boundary

How would one reconstruct a variable that has a non-homogeneous boundary condition defined through the DirichletBoundary class? I am attempting to do something that FEMContext::interior point does and I am having a hard time understanding what elem_subsolutions

Re: [Libmesh-users] Basis Functions at Dirichlet Boundary

Yes, DirichletBoundary objects can do this for you. See introduction_ex4, for example. David On 07/18/2014 05:22 PM, Sahai, Amal wrote: > Can the value of the basis functions be modified so that they are 0 at the > boundaries where Dirichlet Boundary conditions are declared? > > Regards > Amal

[Libmesh-users] Basis Functions at Dirichlet Boundary

Can the value of the basis functions be modified so that they are 0 at the boundaries where Dirichlet Boundary conditions are declared? Regards Amal -- Want fast and easy access to all the code in your enterprise? Index a
