[deal.II] Re: How to provide the VectorMemory<BlockVector > for the class SchurMatrix?

2017-04-26 Thread Jean-Paul Pelteret

Dear Jesse,

You can probably just provide an instance of the GrowingVectorMemory 
 
class 
templated on BlockVector< double >. So this would look something like:
GrowingVectorMemory< BlockVector > memory;
const SchurMatrix schur_matrix (A_inv, B, Dt, C, memory);
...

If its of any help to you, and if you have a C++11 compatible compiler, 
then you could alternatively use the (relatively) new LinearOperator 
 
class and the schur_complement 

 
operator. It provides a more flexible framework with which you could 
perform the same operation.

Kind regards,
Jean-Paul

Re: [deal.II] Re: p4est has to be configured with enabled zlib support

Hi Bruno,

I reinstalled p4est, but zlib didn't get picked up unfortunately. I made
sure it is installed on the machine:
"Installed Packages

[deal.II] How to provide the VectorMemory<BlockVector > for the class SchurMatrix?

2017-04-26 Thread Jesse

Deal all,

I'm using the mixed finite element to solve a Cahn-HIlliard type equation, 
after discretization I obtain a block matrix system. I plan to use the 
class SchurMatrix in deal.ii to obtain the Schur Complement.

The block matrix system is 

* / \ / \ / \ * | A Dt | | u | - | f | * | -B C | | p | - | g | * \ / \ / \ 
/
where A and C are sparse mass matrices, B Dt are sparse stiff matrices. 
But when constructing the SchurMatrix object, I need to provide  'mem'. 
Could someone help me to provide 'mem'?

Thank you in advance.
Jesse

[deal.II] Re: p4est has to be configured with enabled zlib support

2017-04-26 Thread Bruno Turcksin

Lev,

you need to make sure that zlib is installed on your machine and then 
reinstall p4est. zlib should be picked up automatically.

Best,

Bruno

Re: [deal.II] Refining a hyper_ball with a spherical_manifold produces nan values

2017-04-26 Thread Alexander Gary Zimmerman

Thanks, Luca. The behavior is obvious to me now.

As for the documentation: I indeed missed that detail from 
SphericalManifold; but* there is a very misleading statement in the 
hyper_ball documentation:* "You should attach a SphericalManifold 
 to 
the cells and faces for correct placement of vertices upon refinement and 
to be able to use higher order mappings." I would guess that this could 
lead many people to (at least initially) make my mistake, so maybe a small 
edit to note the pitfall could be made here.

So if I want to have a solid sphere domain with a spherical manifold 
throughout it's entirety, I understand that my best option is to use a 
hyper_shell with a very small inside radius.

Re: [deal.II] Refining a hyper_ball with a spherical_manifold produces nan values

2017-04-26 Thread luca.heltai

This is actually not a bug. A spherical manifold is undefined on the center of 
the sphere/ball. You cannot attach set_all_manifold_ids of the spherical 
manifold and attach a spherical manifold to it, since the central cell (the one 
where the cell->center() coincides with the ball center) would not know what to 
do.

This is documented in the SphericalManfold documentation. See the phrase "In 
order for this manifold to work correctly, it cannot be attached to cells 
containing the center of the coordinate system. This point is a singular point 
of the coordinate transformation, and there taking averages does not make any 
sense.”

Best,

L.
