h- and r-adaptivity.
|
|
|
|
A:
|
|
* h-adaptivity gets worse with increasing p (not correct)
|
|
* GH: choose nIter=1 ==> all solutions are incorrect
|
|
* GH: choose nIter=20 ==> all solutions are correct
|
|
* GH: nIter = 5 and Dirchlet bc at x=1.5 ==> aweful for p=20, 100
|
|
Integration of f(x) is not accurate enough. ==> better integration formula needed, see integral(...)
|
|
|
|
B:
|
|
* h-adaptivity is correct
|
|
|
|
C:
|
|
* r-adaptivity
|
|
looks suspicious, but similar to Mandl
