I am a beginner to programming. I am trying to run a simulation of a combustion chamber using reactingFoam.
I have modified the counterflow2D tutorial.
For those who maybe don't know OpenFOAM, it is a programme built in C++ but it does not require C++ programming, just well-defining the variables in the files needed.
In one of my first tries I have made a very simple model but since I wanted to check it very well I set it to 60 seconds with a 1e-6 timestep.
My computer is not very powerful so it took me for a day aprox. (by this I mean I'd like to find a solution rather than repeating the simulation).
I executed the solver reactingFOAM using 4 processors in parallel using
mpirun -np 4 reactingFOAM -parallel > log
The log does not show any evidence of error.
The problem is that when I use reconstructPar it works perfectly but then I try to watch the results with paraFoam and this error is shown:
From function bool Foam::IOobject::readHeader(Foam::Istream&)
in file db/IOobject/IOobjectReadHeader.C at line 88
Reading "mypath/constant/reactions" at line 1
First token could not be read or is not the keyword 'FoamFile'
I have read that maybe some files are empty when they are not supposed to be so, but I have not found that problem.
My 'reactions' file have not been modified from the tutorial and has always worked.
edit:
Sorry for the vague question. I have modified it a bit.
A typical OpenFOAM dictionary file always contains a Foam::Istream named FoamFile. An example from a typical system/controlDict file can be seen below:
FoamFile
{
version 2.0;
format ascii;
class dictionary;
location "system";
object controlDict;
}
During the construction of the dictionary header, if this Istream is absent, OpenFOAM ceases its operation by raising an error message that you have experienced:
First token could not be read or is not the keyword 'FoamFile'
The benefit of the header is possibly to contribute OpenFOAM's abstraction mechanisms, which would be difficult otherwise.
As mentioned in the comments, adding the header entity almost always solves this problem.
If I begin with a wholly Japanese sentence and run it through MeCab, I get something like this:
$ echo "吾輩は猫である" | mecab
吾輩 名詞,代名詞,一般,*,*,*,吾輩,ワガハイ,ワガハイ
は 助詞,係助詞,*,*,*,*,は,ハ,ワ
猫 名詞,一般,*,*,*,*,猫,ネコ,ネコ
で 助動詞,*,*,*,特殊・ダ,連用形,だ,デ,デ
ある 助動詞,*,*,*,五段・ラ行アル,基本形,ある,アル,アル
EOS
If I smash together everything I get from the last column, I get "ワガハイワネコデアル", which I can then feed into a speech synthesis program and get output. Said program, however, doesn't handle English words.
I throw English into MeCab, it manages to tokenise it (probably naively at the spaces), but gives no reading:
$ echo "I am a cat" | mecab
I 名詞,固有名詞,組織,*,*,*,*
am 名詞,一般,*,*,*,*,*
a 名詞,一般,*,*,*,*,*
cat 名詞,固有名詞,組織,*,*,*,*
EOS
I want to get readings for these as well, even if they're not perfect, so that I can get something along the lines of "アイアムアキャット".
I have already scoured the web for solutions and whereas I do find a bunch of web sites which have transliteration that appears to be adequate, I can't find any way to do it in my own code. In a couple of cases, I emailed the site authors and got no response yet after waiting for a few weeks. (Just how far behind on their inboxes are these people?)
There are a number of directions I can go but I hit dead ends on all of them so far, so this is my compound question:
MeCab takes custom dictionaries. Is there a custom dictionary which fills in the English knowledge somewhat?
Is there some other library or tool that can take English and spit out Katakana?
Is there some library or tool that can take IPA (International Phonetic Alphabet) and spit out Katakana? (I know how to get from English to IPA.)
As an aside, I find that the software "VOICEROID" can speak English text (poorly, but adequately for my purposes). This software uses MeCab too (or at least its DLL and dictionary files are included in the install.) It also uses another library, Cabocha, which as far as I can tell by running it does the exact same thing as MeCab. It could be using custom dictionaries for either of these two libraries to do the job, or the code to do it could be in the proprietary AITalk library they are using. More research is needed and I haven't figured out how to run either tool against their dictionaries to test it out directly either.
I have a flat file below. I'm having trouble with the schema with this layout. I switched it around to have a header and a detail and created an application with no problems, but the customer won't change the layout. This is probably pretty basic, but I'm a beginner. How do I take certain fields from this layout and create a header and a detail? The last date field needs to be in the header so you can see how it's random.

The basic problem here is the Flat File Disassembler does not support the concept of splitting/debatching based on changing values, PO207730CO -> PO207814CO for example.
So, you'll have to regroup by PO number at some following step.
You have a few options:
Use a Custom XSLT Map to group the lines based on the PO Number,
then split, by using a Receive Pipeline on an Orchestration for example.
https://social.technet.microsoft.com/wiki/contents/articles/17985.xslt-muenchian-grouping-biztalk-complex-transformation.aspx
Use an xPath Debatching Pattern in an Orchestration. http://www.biztalkgurus.com/biztalk_server/biztalk_2004/m/biztalk_2004_samples/32438.aspx
Either way, you would parse the flat file as you are now, row by row.
Thanks for the replies.
I went with an SSIS package to preload a table and build the pipe delimited file. I have Biztalk then picking up that file and debatching it the way I need it.
Good day. The programs function is to take an equipment number (or none), display that number with a description (or all) in alv, and then run IE03 should the user double click on
Program worked fine in client 110, but in 150 a runtime error happens. This morning I tried to make a new program with a shorter name (only lead I had), activated it (window popped up asking me to activate the previous version as well). That didn't work and now the original doesn't work in either.
The program "SAPLSKBH" is terminating because program line is too long, being 78 chars wide which is too much for the internal table "\FUNCTION=K_KKB_FIELDCAT_MERGE\DATA=L_ABAP_SOURCE[]"
It sounds like you are using REUSE_ALV_GRID_DISPLAY for output, is that correct?
Check you source code; somewhere you have a line that is more than 78 characters. The function K_KKB_FIELDCAT_MERGE takes the source code of your program to produce a structure that corresponds to the table/structure you give it. (In the old days, there was a limit of 78 characters width for a line of ABAP code, and this is an old function module).
You can alternatively build a field catalog yourself in code, rather than use this function.
I developed a new method of encrypting information. It does not comply with standard methods of encryption and was custom made to encrypt info stored in session cookies.
It basically works like this:
-It takes a standard 72 char string as it's IDENTITY or password. There could be more than a million variations of this.
It then uses a pre-defined set of randomly generated variations of text and uses that to hide the actual content. However, it has special chars hidden in each enrypted line to help identify how to decrypt it.
My reason for posting here is to see if anyone here could (a) crack it or (b) give me some advice on how to make it better.
I am not too reluctant to give too much info yet as this is still in aplha stage and not the finished project.
Here is an example. It is the 50 US states in random order. Please note that even if I keep the same order, each time it will look different. To prove that, I will run it twice with the same order used:

As you can see, it looked different for the same order of 50 lines of text.
So, any ideas?
Any encryption method which relies on the secrecy of the algorithm is flawed. The attacker will always know the algorithm. See Kerckhoff's Principle for a longer explanation.
It is absurdly easy to write an algorithm that you yourself cannot break, anyone can do it. However, unless you are a professional cryptographer, a professional cryptographer will find it easy to break. Have you tested your algorithm against differential cryptanalysis? Do you even know what differential cryptanalysis is?
There are many excellent cyphers available already, suitable for many different purposes and with varying levels of complexity and security. Don't reinvent the wheel; use an existing cypher.
