Milestone 1: Write the initial version of the manual/readme.md file
Milestone 1: Update readme.md for the new frequency-dependent stuff
The readme.md file has a section on verification that we compute the correct answer. This still uses the scheme from before #9, where density and wave speed are provided in the .prm file for all frequencies. The description of the inputs for these verification cases needs to be updated now that #9 is done.
Milestone 2: Fix the output format of the P and U matrices
From Jason's write-up:
Eventually for a system with 2 ports, Ares is going to need a matrix that looks like this:
| m11 m12 m13 m14 | | P1 | = |b1|
| m21 m22 m23 m24 | | U1 | |b2|
| P2 |
| U2 |
where the velocities U1 and U2 are defined to be into the node (or into the volume).
For a system with 3 ports, I'm going to need a matrix that looks like this:
| m11 m12 m13 m14 m15 m16| | P1 | = |b1|
| m21 m22 m23 m24 m25 m26| | U1 | |b2|
| m31 m32 m33 m34 m35 m36| | P2 | |b3|
| U2 |
| P3 |
| U3 |
etc.
For a volume with N ports, I need N linear equations relating the 2*N DOF's (P1-PN and U1-UN) to each other.
(Of course, you need 2*N equations to solve for the full system. The other N equations come from how the volume's ports are connected to the other components in the equivalent circuit model in Ares.)
For your problem, the b coefficients will all be 0 (i.e. there are no sources in your volume).
Also, we don't need all of the m coefficients. Because this is a linear system, we know that the 2N DOF's can be related to each other through a simple NxN system of equations that can look like:
|Q11 Q12 |* |P1| = |U1|
|Q21 Q22 | |P2| |U2|
which can be rewritten as
|Q11 -1 Q12 0| * |P1| = |0|
|Q21 0 Q22 -1| |U1| |0|
|P2|
|U2|
The form for the N=3 system will be
|Q11 -1 Q12 0 Q13 0| * |P1| = |0|
|Q21 0 Q22 -1 Q23 0| |U1| |0|
|Q31 0 Q32 0 Q33 -1| |P2| |0|
|U2|
|P3|
|U3|
So half of our mij coefficients are either -1 or 0.
To find the N*N Qij coefficients, I solve the system N times:
once with P1=1, P2-PN=0, and then I solve for U1-UN
once with P2=1, P1=P3-PN=0, and again I solve for U1-UN
once with P3=1, P1=P2=P4-PN=0, and again I solve for U1-UN
. . .
once with PN=1, P1-P(N-1)=0, and again I solve for U1-UN
Then from these N solutions, I'm able to solve for the N*N Qij coefficients. I'll go through the math of this for the N=2 case.
Let's rewrite
|Q11 Q12 | |P1| = |U1|
|Q21 Q22| |P2| |U2|
as
|P1 P1 0 0 | * |Q11| = |U1|
| 0 0 P1 P2 | |Q12| |U2|
|Q21|
|Q22|
So we've got N=2 equations and N*N unknown.
Now suppose we know P1, U1, P2, and U2 for N separate unique conditions. Let's call these 2 unique conditions:
P1_1, U1_1, P2_1, U2_1 for condition "_1"
P1_2, U1_2, P2_2, U2_2 for condition "_2"
|P1_1 P2_1 0 0 | * |Q11| = |U1_1|
| 0 0 P1_1 P2_1| |Q12| |U2_1|
|P1_2 P2_2 0 0 | |Q21| |U1_2|
| 0 0 P1_2 P2_2| |Q22| |U2_2|
So now we have N unknowns and N equations.
We can solve for Qij's and from there assign the mij coefficients.
For a N=3 system, we have NxN=3*3 = 9 unknowns, but we get 3 equations for every solution and the system to be solved is
|P1_1 P2_1 P2_1 0 0 0 0 0 0 | * |Q11| = |U1_1|
| 0 0 0 P1_1 P2_1 P3_1 0 0 0 | |Q12| |U2_1|
| 0 0 0 0 0 0 P1_1 P2_1 P3_1 | |Q13| |U3_1|
|P1_2 P2_2 P2_2 0 0 0 0 0 0 | |Q21| |U1_2|
| 0 0 0 P1_2 P2_2 P3_2 0 0 0 | |Q22| |U2_2|
| 0 0 0 0 0 0 P1_2 P2_2 P3_2 | |Q23| |U3_2|
|P1_3 P2_3 P2_3 0 0 0 0 0 0 | |Q31| |U1_3|
| 0 0 0 P1_3 P2_3 P3_3 0 0 0 | |Q32| |U2_3|
| 0 0 0 0 0 0 P1_3 P2_3 P3_3 | |Q33| |U3_3|
Also write output data into a CSV file
Milestone 2: Implement the mesh refinement criterion
As stated in the readme.md, we want to do this:
On the other hand, if the number of mesh refinement steps is negative,
then the mesh is adapted using the following algorithm. For a given
wave speed, we can compute the wavelength of oscillations for a
given frequency _w_ via
lambda = c/f
= c/(w/(2pi))
If `lambda` is larger than the diameter of the domain, then we replace
it by the diameter of the domain since that is the largest wavelength
at which the solution can vary.
We can then determine a frequency-adapted mesh size in the following
way: We want that there are at least _N_ grid points per wave
length. Since there are as many grid points per cell as the polynomial
degree _p_, this equations to requiring that the mesh size _Delta x_
satisfies _Delta x / p <= lambda/N_
or equivalently: _Delta x <= lambda/N * p_. The `Mesh refinement steps`
parameter is then interpreted as _N_ if it is negative.
In the code, we just need to compute lambda correctly -- right now it is simply set to 1000.
Milestone 1: Name output files by the number of the frequency
As $title says. This requires moving the number of the frequency through from the place where we call the function.
Milestone 1: Correct the definition of the velocity on ports during postprocessing
Concatenate all .csv files into one
Ask Jason whether we need this.
Finish documenting point values in the example section
Reverse the order of indices in the U, P, and M matrices
Columns should be source port, rows destination port. Currently, it's the other way around.
Milestone 1: Verify correctness of the code
Use a simple pipe with two ports, for which I can write down the exact solution of the problem.
Visualize boundary indicators
...so that we can actually see what geometry we are given.
Milestone 2: Read COMSOL files
Write a reader for the COMSOL .mphtxt file format:
https://www.comsol.com/fileformats
See also Jason's email from 11/2/2021.
Signal failure
<output prefix>solver_failure_signal.txt
This file is created by dealII_3D and indicates that there was an error in solving the problem passed to it. Information about the error will be placed into the output_log.txt file. ealII_3D will terminate after this file is created.
Move surface output into visualization/ folder
Related to #19.
Flag that determines that we only want diagnostic output, no solution
Document CSV output file
Output boundary indicators and areas
Could you report the surface areas and names of the interface surfaces?
It would be nice if this could be a separate command call to helmholtz.exe where helmholtz.exe loads the mesh file and just reports some information about the mesh. Currently the number, names and area of the interface areas are needed.
Milestone 1: Correct the boundary conditions on the output ports
Right now, we prescribe unit pressure at the source port and zero pressure at the other ports. For all other parts of the boundary, we prescribe Neumann values
nabla p = 0
I suspect, however, that setting the pressure to zero at the outlet ports is not what is really wanted. Need to discuss with Jason.
Milestone 1: Implement frequency-dependent density and bulk modulus
For example, for air:
% frequency(Hz) density(kg/m3) bulk modulus(Pa)

Complete point value output for the with-attenuation case.

Milestone 2: Standardize and document error reporting
One thing I didn't put into my interface document is a way for deal II to report errors. !!!!
We're going to need a way to report them in a way that gives the user a decent chance to find out what's wrong with ow he setup the mesh and interface areas.
Can you add this to the interface document? It can't just be "error while reading file"... It has to give them enough information to help figure out what's wrong.
My general rule for how software should work is : what would YOU want the software to do/say if you were the user and not the programmer??? That's the way the software should be written.
Milestone 1: Create success file
<output prefix>success_signal.txt
This file is created by dealII_3D and indicates that all of the frequencies specified in <cmd_filename> have been successfully solved for. dealII_3D will terminate after this file is created.
Milestone 1: Implement a way to scale STL geometry to SI units
there is some confusion with units because the STL file does not use
SI units but uses mm for lengths, whereas internally I use SI units)
When I send an STL file to someone, I usually tell them the units. Usually it's mm, sometimes it's inches. Then when the people import it into whatever CAD software they're using, they apply a scaling factor to represent it in whatever units they use in their CAD file.
So I suspect we'll need to have them provide the units used in the STL file, or perhaps a simple multiplicative value that will convert the units to meters.
Fix check_for_termination
In both the Helmholtz and Biharmonic programs, check_for_termination_signal() exits the program when requested, but also returns a value. Furthermore, that value is ignored almost everywhere. Fix this in both program: if it exits, we don't need a return value.
Milestone 1: Output pressure and velocity at "listening points"
From Jason:
Also, I wanted the ability to output information on "listening" points inside of the volume. I don't see this mentioned anywhere in your SOW that I have. Along with the port interface areas, I want the user to be able to specify points in the volume where the pressure and particle velocity vector can be computed for. This will consist of a similar transfer matrix dependent on the inputs at the ports.
Validate the correctness of results for the 5cm cylinder
See an earlier email by Jason with the specifics of the testcase.
Figure out whether the solution for the test case should/should not be symmetric
Make sure we write to the common output files under a mutex.
Document the surface output in the readme.md file
Milestone 2: Write each frequency results into its own files
From Jason:
One thing that I had to do with biharmonic was to have it write each frequency result to it's own file. I tried to use frequency_response.txt, but I'd get read/write collision errors when your solver and Ares were both trying to access it at the same time.
Finish documenting the plain text output files
Add a table of contents to the readme.md file
Using this style:
# Table of contents
1. [Introduction](#introduction)
2. [Some paragraph](#paragraph1)
1. [Sub paragraph](#subparagraph1)
3. [Another paragraph](#paragraph2)
## This is the introduction <a name="introduction"></a>
Some introduction text, formatted in heading 2 style
## Some paragraph <a name="paragraph1"></a>
The first paragraph text
### Sub paragraph <a name="subparagraph1"></a>
This is a sub paragraph, formatted in heading 3 style
## Another paragraph <a name="paragraph2"></a>
The second paragraph text
Milestone 2: Use file prefix
Related to #12:
Also, I want all of the files to start with their own unique prefix so I can run multiple instances of your solver and still use the same directory. So each instance will have it's own unique prefix for the interface files.
