Answer :

When you need to perform batch processing. In this example, PyTecplot gives you:

Direct get right of entry to in your information – Use PyTecplot to load any facts report format supported by using Tecplot 360 and access the statistics at once to carry out publish-processing in any other case no longer possible within Tecplot 360 or with macros.
Speed – PyTecplot executes faster than equal Macros. In one use case we reduce execution time from 18 mins all the way down to 7.3 seconds.
A actual programming language – PyTecplot lets in you to apply all of the utilities afforded by means of Python consisting of arrays, string processing, and integration with other Python applications. You can also debug and broaden the usage of the equal tools you’re already the usage of in your present Python scripts.
Integration with different procedures – Python lets in to you extra effortlessly combine Tecplot 360’s capabilities into existing workflows.

Question thirteen. Can I Record A Python Script?

Answer :

Not yet. This is something that we plan to address inside the destiny.

Question 14. How Do I Install Pytecplot?

Answer :

First off, PyTecplot calls for an set up of Tecplot 360 2017 R1 or later. PyTecplot is also hosted on pypi.Python.Org so you surely want to run ‘pip deploy pytecplot’ from a command set off. Easy as Py!

PyTecplot is also blanketed inside the Tecplot 360 installation so you can install from there when you have an overzealous firewall or want to make sure the PyTecplot version you’re putting in is assured to be well suited along with your version of Tecplot 360.

Question 15. You Had A Python Api In Tecplot 360 2013, What’s Different About This One?

Answer :

We first of all added a Python API in 2008. That Python API turned into a light-weight cover over our C API and did no longer experience like Python. That API also required Python to be hooked up along with Tecplot 360 which brought on installation conflicts. Finally, scripts written using that API needed to be run within Tecplot 360, making it very difficult to debug your script.

PyTecplot is a totally redesigned API that embraces several capabilities of the Python language making it a more natural interface to use inside a Python script. It is now a pure-python module that masses Tecplot 360's libraries on import.

Question 16. How Much Of The Api Is Currently Available?

Answer :

At the time of our initial launch in 2017 we estimate over 60% of the style settings to be complete. This ought to fulfill the widespread majority of early adopters. We will retain to develop the API until we reach nearly a hundred% of what is available via the macro language. For APIs which have not been evolved yet you may use tecplot.Macro.Execute_command() to use Tecplot macro instructions.

Question 17. Are You Getting Rid Of The Macro Language?

Answer :

No. Though PyTecplot can use macro instructions. This allows macro specialists to easily merge the benefits of Python (like arrays, good judgment, string processing) with their information of the Tecplot macro language.

Question 18. How Does Pytecplot Work?

Answer :

When PyTecplot is imported in a consumer's script, Tecplot 360’s engine is began up in batch mode. Any installation of Python (64-bit, version 2.7 or 3.Four+) will work, that means you could use wellknown Python tools to put in writing and debug your code. Our first release of PyTecplot will support the use of Tecplot 360 from within Python to enable batch mode processing and workflow integration. A destiny launch will increase PyTecplot to assist interactive use of Python from within a going for walks Tecplot 360 instance.
