I have a very simple question. Normally in other programs, such as word, you can just simply save the document under a different resulting in two separate documents. However, this doesn't work for AnyLogic. Does anyone know how to duplicate a project?
If you do file save as it will create a new alp file for you
But for it to be a truly different model you need to change the Java Package to something unique... See how it is kept as model24 in my screenshot
But be careful it can have some unwanted consequences in a very complex model and you will need to fix these manually, but all doable

I am working on physics simulation research. I have a large fixed grid in one of my projects that does not vary with time. The fields on the grid, on the other hand, vary with time in the simulation. I need to use VTK to record the field data in each step for visualization (Paraview).
The method I am using is to write a separate *.vtu file to disk at each time step. This basically serves the purpose, but actually writes a lot of duplicate data (re-recording the geometry of the mesh at each step), which not only consumes more disk space, but also wastes time on encoding and parsing.
I would like to have a way to write the mesh information only once, and the rest of the time only new field data is written, while being able to guarantee the same visualization. Please let me know if VTK and Paraview provide such an interface and how to implement it.
Using .pvtu and refer to the same .vtu as Piece for each step should do the trick.
See this similar post on the ParaView discourse, and the pvtu doc
EDIT
This seems to be a side effect of the format, this is not supported by the writer.
The correct solution is to use another file format ...
Let me provide my own research findings for reference.
As Nico said, with the combination of pvtu/vtu files, we could theoretically implement a geometry structure stored in a separate vtu file, referenced by a pvtu file. Setting the NumberOfPieces attribute of the ptvu file to 1 would enable the construction of only one separate vtu file.
However, the VTK library does not expose a dedicated operation interface to control the writing process of vtu files. No matter how it is set, as long as the writer's input contains geometry structures, the writer will write geometry information to disk, and this process cannot be skipped through the exposed interface.
However, it is indeed possible to make multiple pvtu files point to the same vtu file by manually editing the piece node in the ptvu file, and paraview can recognize and visualize such a file group properly.
I did not proceed to try adding arrays to the unstructured grid and using pvtu output.
So, I think the conclusion is.
if you don't want to dive into VTK's library code and XML implementation, then this approach doesn't make sense.
if you are willing to write a series of files, delete most of them from the vtu file, and then point all the pvtu's piece nodes to the only surviving vtu file by editing the pvtu file, you can save a lot of disk space, but will not shorten the write, read, and parse times.
If you implement an XML writer by yourself, you can achieve all the requirements in theory, but it requires a lot of coding work.
Good afternoon, Stack Overflow!
To begin, I would like to say that I'm extremely new to the world of scripting but am eager to learn as much as I can. Currently, I am trying to learn how to create a script that would compare two different CSV files for discrepancies and then output to another Excel sheet the discrepancies.
One one sheet, there are a bunch of columns of data for which I only need a couple columns of. For example:
File 1:
Name;Bug;Status;Due Date;Nonsense;Bananas;Issue Key
File 2:
Name;Bug;Status;Cross Reference;Status;Due Date
One thing I would like to point out is that the "Issue Key" column is synonymous with "Cross Reference" in File 2. I know that I could use this to my advantage but can't seem to understand how to start. I'd like to be able to compare the data for 3 to 4 columns between the two files and see any changes/discrepancies.
Is there a reason you want to use PowerShell? So far from what you describe it seems it would make more sense to use a differencing tool. https://winmerge.org/ is one such example and there are lots of others out there. OTOH If this is something you need to do consistently on a large scale it would probably make more sense to do it programmatically.
I'm getting started with Knowledge Studio and Natural Language Understanding.
I'm able to deploy a machine-learning model toNatural Language Understanding and use the API to query it.
I would know if there's a way to deploy only the pre-annotator.
I read from Knowledge Studio's documentation that
You can deploy or export a machine-learning annotator. A dictionary pre-annotator can only be used to pre-annotate documents within Watson Knowledge Studio.
Does exist a workaround to create a model that simply does the job of the pre-annotator, i.e. use dictionaries to find entities instead of the machine-learning model?

You may need to explain this better in what you need.
WKS allows you to pre-annotate documents with dictionaries you upload. Once you have created a ML model, you can alternatively use that to annotate your training documents, and then manually correct. As you continue the amount of manual work will reduce after each model iteration.
The assumption is that you are creating a model with a reasonable amount of examples. In your model results, you will want the mention/relations to be outside or close to outside the gray area of the report.
The other interpretation of your request I took was you want to create a dictionary based model only. This is possible using the "Rule-Based Model" functionality. You would have to create the parsing rules but you just map what you want to find to the dictionary/rule.
Using this in production though is still limited. You should get a warning when you deploy these kinds of models.
It's slightly better than just a keyword search as you can map items to parts of speech.
The last point. The purpose of WKS is to create a machine learning model which will do the work in discovering new terms you haven't seen before. With the rule based engine it can only find what you explicitly tell it to find.
If all you want is just dictionary entries, then you can create a very simple string comparison solution, but you lose the linguistic features.
I have an object that contains about half a dozen properties. I expect to save maybe a dozen or more of these objects to my documents folder. My solution is to save the data using NSEncoding and NSKeyed/Archiver/Unarchiver. Anyone have a better strategy or approach.
NSKeyedArchiver/Unarchiver will work fine. If each file only has a half dozen properties, you might consider whether putting the entire object list in one file would be simpler for you to load/save/keep consistent.
I'm trying to clean up a database by first finding unreferenced objects. I have extracted all the database objects into a list, and all the ddl code into files, I also have all the Java source code for the project.
Basically what I want to do (preferably in Perl as it's the scripting language that I'm most familiar with) is to somehow index the contents of all the extracted database ddl and Java files (to speed up the search), step through the database object list and then search through all the files (using the index) to see if those objects are referenced anywhere and create a report.
If you could point me in the right direction to find something that indexes all those files in a way that I can search them (preferably in Perl) I would greatly appreciate it.
The key here is to be able to do this programatically, not manually (using something like Google desktop search).
Break the task down into its steps and start at the beginning. First, what does a record look like, and what information in it connects it to another record? Parse that record, store its unique identifier and a list of the things it references.
Once you have that list, invert it. For each reference, create a list of the objects referenced. Count them by their identifier. You should be able to get the ones whose count is zero.
That's a very general answer, but you asked a very general question. If you are having trouble, break it down into just one of those steps and ask a more specific question, supplying sample data and the code you've tried so far.
Good luck,
An interesting module you might use to do what you want is KinoSearch, it provides you the kind of indexing you said to be looking for. Then you can go through the object identifiers and check if there are references to it.
