How to read .cas and .dat files obtained from ansys fluent?

[akaszynski]

I'd have to write a reader for those as well as pyansys can only read files generated from ANSYS APDL. Would you be willing on volunteering some example files and some sample code?

Dear Alex,

Thank you for replying. I am currently working on a project which involves reading .cas and .dat files generated from fluent, on Python. Therefore, I would be very happy to contribute as I have to read some files of the same format.

Yours truly Divyanshu

I was wondering how do we interpret bunary files generated by fluent. Is this information given somewhere?

Thanks.

I'll have to add the reader at some point. My work doesn't normally include reading CFD files, so it might take a while for me to add this feature in my spare time.

[DivyanshuGola]

You can take your time. Also I wanted to know where do I get the information about the binary file, that is how do I comprehend it myself.

After a quick search, I haven't found any resources describing the dat file format from ANSYS.

OpenFOAM has a converter that gives some insight into the format of the file: http://www.openfoam.com/documentation/user-guide/fluent.php

As OpenFOAM can read in fluent files, you might want to try out it for now.

Hello Alex,

I found this while searching for formats of data and case files generated by Fluent. https://www.sharcnet.ca/Software/Fluent6/html/ug/node1490.htm Do you think we can proceed on these lines?

Good find! Yes, I think it will be possible to start work on it. Do you have some example data and case files?

[DivyanshuGola]

Yes, I have some sample case and data files. I have attached them with this mail.

I think you'll have to go onto GitHub on this thread to upload files.

[DivyanshuGola]

Github doesn't support uploading these type of files.......I think should be able to download them from gmail.Please give me your gmail id.

Hello Alex, I tried reading the case and data files using :

with open('sample.cas') as f: content1=f.readlines()

I am able to print the contents as a list. But I am not able to find any values or coordinates of nodes in the file as shown in the user guide (link that i sent you earlier). Can you help me with this? By the way, are you able to extract something useful out of the files?

Thanks.

CFD results are out of scope of this project at the moment.

How to read .cas and .dat files obtained from ansys fluent?

Hello, blogger, have you found a way to read the fluent dat file with python? My most research also needs to use python to read the node data (pressure, density, etc.) in the dat file

[DivyanshuGola]

Hi,

The ansys handbook has the format specified for the data files. They are binary files which you can read using various numpy modules.

Hope this helps.
