Dear Wolfgang, dear community,
obviously this is a mistake. I checked the source files which we have used for
results in corresponding paper.
There I have found the following coding:
resid_old = resid;
resid_vector = system_rhs_newton;
resid_vector.compress(VectorO
Thanks a lot, Daniel and Wolfgang!
What I understood was that since the SUPG and PSPG terms are integrated
over the cell interiors so the laplacians can be ignored while using Q1/Q1
element without any singularity problems on the cell edges.
Thanks!

Dear all,
Since the inclusion of Transfinite interpolation, I have been successful on
working with this powerful technique in my research. I had coded a mesh
implementing concentric circles, where the inner most is shifted a small
distance s. All concentric circles are labeled 100+i, where i is

These terms are simply zero if you consider Q1 elements for the velocity. I
That's true only if you're on affine meshes. In general, the Laplacian
of a Q1 function on an arbitrary mesh is not zero.
That doesn't mean, though, that it may not be vali

Hi,
I'm working on a solver to solve Navier-Stokes equations using the
Streamline Upwind Petrov-Galerkin (SUPG) and Pressure Stabilization
Petrov-Galerkin (PSPG) method, combined with Newton's iteration and FGMRES
iterative method. However, I had some difficulties with implementing the
formula
