SLIDE 3

Grids with distmesh, mesh2d solution to Poisson’s equation

JU/DW JU

SLIDE 4

Grids, cd

Use deal ii, and Blossom for meshing

SLIDE 5

Cd

DF GX/DF

SLIDE 6

More exotics

AA/CS ZY

SLIDE 7

Sometimes something goes wrong (Lab 5)

SLIDE 8

Lack of coercivity

SLIDE 9

More exotic domains: solution to an elliptic equation and to the wave equations

SLIDE 10

Eigenfunctions for an exotic domain

ME/EH

SLIDE 11

More exotic domains and eigenfunctions

SLIDE 12

Sometimes something goes wrong (Lab 5)

But can be corrected

SLIDE 13

And eventually gets corrected

SLIDE 14

Eigenfunctions for Dirichlet problem

AA/CS ZY

SLIDE 15

Eigenfunctions

SLIDE 16
