Show a better example to prove that the equations are not the one that the professor solved.

comment Solve a PDE on a domain $\Omega$ with given boundary conditions
This is one of the questions I'm considering :). It's a pity that NDSolve can not yet handle irregular rigion, and this seems to be the only question that tried to deal with this issue in this site so long.

This de-optimization has already existed since v8.

comment NIntegrate receiving a function with NumericQ which returns a list
Er… Sorry but I can't understand the added explanation very well 囧, and I just noticed that the listPart isn't actually used in your work-around… BTW, have you considered something like Method->{Automatic, "SymbolicProcessing"->False"}?

Also faster than my c11, but maybe a little hard to extend to more general cases?

About 3 times faster than my c11 now :).

I'm sorry but this approach is even slower than my c1 and no simpler than it.

@Kuba Well, I should say it's more general… maybe the new list is generated by $f(a)$ and $g(a)$, or even $f(a1, a2)$ and $g(a1, a2)$…

comment How to collect result continuously (interruptible calculation) when running parallel calculations?
Oh, I overlooked the existence of CheckAbort… thanks for your explanation!

comment NIntegrate receiving a function with NumericQ which returns a list
I can't think out a work-around with the existence of _?NumericQ, but what do you really want? Just a explanation for the failure? A numerical integration without symbolic processing for a list of expressions? Or something else?

Well… isn't the Reap and ParallelSow redundant in the last sample? I think Catch has only caught the output of ParallelTable here.
