[deal.II] deal.II binary package won't open on Mac OS
Hello all, I've recently seen some issues opening the version 8.4.1 Mac OS binary package. After downloading the .dmg file and copying the application to the Applications folder, double-clicking it doesn't launch the terminal window like it should. The "verifying..." dialog pops up and then the deal.II.app freezes. If I open the application in Finder with "Show Package Contents" and open "/Contents/Resources/bin/dealii-terminal" everything is fine. Both computers I saw this on has OS X El Capitan (unfortunately it was at an event where I was helping users install deal.II, so I don't have those computers handy anymore). On my own laptop (also running El Capitan), it works fine. Has anyone else had a similar issue? Any ideas on what the problem could be? Two different users on two different machines had the same issue.

Maybe it will look correct but something that you don't show is wrong or the person looking at your code misses something obvious. On top of that if everybody on the mailing list starts asking if their code is correct, we won't have time to answer other questions. What you need to do is to write a test, i.e. a small code that use the function you wrote, and you need to make sure that the code works like it should on this simple example. This way not only you will be able to convince yourself that the code works like it should but you can make sure six months from now that everything is still working. If your test doesn't work like expected, then you may want to ask questions on the mailing list.

[deal.II] Re: Assemble system with variational right hand side
Thanks for the reply,
I just wanted to make sure that whether I implemented it right,
but I still cannot sure whether I am doing correctly. Let me be with
more specific questions.
First, Yes I am considering 2-dimensional flow.
if I writes a code that looks as previous,
template
void
RightHandSide::vector_value (const Point ,
Vector ) const
{
values(0) = pow(p[0],2);
values(1) = pow(p[1],2);
* values(2) = 0.0; // I assumed this always zero. because f is 2
dimensional force, and we will not have third component of f*.
}
1) whether my interpretation of 'values(2) is correct' - marked with red
line
2) If we considered a vector value test function phi=(*v,*q)= (v_x, v_y ,
q), the right hand side term in weak form should look like this
RHS = (*v, f* ) at domain o mega.
since both *v* and* f* is vector that has two direction , (x and y) , the
calculation should be conducted in both direction
but in the following code, it seems that I am multiplying only the first
component v and f...
Do I understand this appropriately?
In this sense, I don't understand my code well... cuz it looks like...
*const unsigned int component_i =*
* fe.system_to_component_index(i).first; <- Here I only said the first *
*component...*
* local_rhs(i) += fe_values.shape_value(i,q) **
* rhs_values[q](component_i) **
* fe_values.JxW(q);*
Shouldn't this be some thing like this?
*const unsigned int component_i =*
* fe.system_to_component_index(i).first; *
*const unsigned int component_j = *
* fe.system_to_component_index(j).second; *
* local_rhs(i) += (fe_values.shape_value(i,q) **
*rhs_values[q](component_i)) *
*(fe_values.shape_value(i,q) **
*rhs_values[q](component_j)) *
* fe_values.JxW(q);*
