open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello everyone,

I've recently upgraded my system to Windows 11 and I'm encountering significant compatibility issues with BlueKenue. I have tried multiple versions of the software, including 3.12.10, 3.12.0, 3.11.7, 3.10.0, and 3.8.4, but none seem to work correctly on the new OS.

While I was using Windows 10, I never experienced any problems with BlueKenue. However, since the upgrade, I'm facing a couple of critical issues:

1. Node Selection Problem: Whenever I try to select a node by double-clicking on it, the program freezes.

2. File Opening Issue with Version 3.12.10: With the latest version I have (3.12.10), I can't even open an r3d.slf file. The program shuts down immediately after attempting to open the file.

Here are some steps I've already taken in an attempt to resolve these issues:
- Running BlueKenue in compatibility mode for previous Windows versions.
- Running the software as an administrator.
- Ensuring my Windows 11 is up to date with all the latest updates.

Unfortunately, none of these measures have been successful.Any insights or suggestions would be greatly appreciated. Thank you for your time and help!

Best regards,
Aymane

Hi Aymane,

I don't think the problems you are experiencing are because of
Windows 11 per se.
I'm using Windows 11, Version 32H2, OS build 22631.3296 without these issues.
BK versions V3.3.4 through 3.12.14

Can you share the files that are causing you grief?
Can you also share your computer configuration? CPU, memory, GFX card...

Cheers... Martin

Hi Martin,

Thank you for your reply.

I have attached some files. The first file is `geo.slf`, which is giving me trouble when I try to select a node by double-clicking (I also tested with other geometry files from other models and same issue); Bluekenue freezes when I attempt this. This wasn't an issue previously when I was using BK v3.10.0 on Windows 10.

I could not include a 3D result file. I even chopped the larger result file that was too big to upload. The chopped version is 71 MB and could also not be uploaded here. BK crashes when attempting to open a 3D result file.

My dev version of Blue Kenue seems to be working properly with your file...

Hi Aymane,

In the past we sometimes experienced selection problems that we caused by faulty video drivers. Try updating the drivers by downloading the latest from the gfx card manufacturers web site. The default Windows drivers are not necessarily the best.

Regarding the telemac 3D slf file loading problem.
There is a known issue with 3D node value assignment and Alan has it on his radar.

However, I can't replicate a crash.
Perhaps you could upload your file to Dropbox or some such site.

Cheers... Martin

Hi,

I am a colleague of Aymane and I can report on some testing being done today. I have a similar computer set-up and running on Windows 11.

Please note that the 3D selafin files we use are double precision files. We only face problem opening 3D double precision files. We have no issue with single precision 3D files or even double precision 2D files.

I tried to go back to earlier versions of BK and could see that the alpha version 3.10.0 was working fine, 3D double precision files can be opened without problem.

With 3.12.13 or 3.12.14, 3D double precision files are loaded with erroneous values (3.12.13) or simply crashes at start of file scanning (3.12.14).

So, at least we can go back to 3.10.0 and work with 3D double precision files, but it seems that there is an issue in the more recent versions.

We will try to make one example file available for you to perform further testing.

Kind regards
PL

This is a very helpful comment. Thank you for that! There have been some very deep changes recently. To diagnose the root cause of your grief, I'd have to debug using a failing file...

Looking forward to getting one

Kindly,
Alan
