[Libmesh-users] [RB] Question about a poseteriori error estimation

[<ss...@pu...>]

Hello, all.

 

I have a question about the RB error estimation in LibMesh.

 

I know that the maximum error bound is computed in the function
"RBConstruction::compute_max_error_bound()."

Here we should compute the "dual norm of residual" using the function
"compute_residual_dual_norm(N)."

But I do not know exactly if this "dual norm of residual" is "X-norm" or
"energy-norm," where "X-norm" is parameter-independent and "energy-norm" is
parameter-dependent.

 

When I looked at the "compute_residual_dual_norm(N)" code, the current
parameter is called by the "const RBParameters & mu = get_parameters();"
code line.

So I guess the "dual norm of residual" is the "energy-norm," and I would
like to ask if it is correct.

 

I always thank you for your help.

 

Regards,

SKang
