Problem with program launch
After installation (Windows 11) and starting BARAMFlow or BARAMMesh, a Baram... process appears in Task Manager and disappears after 1-2 seconds. The program fails to start. No error messages are displayed. In which direction should I look for the error?
Hi Konstantin,
I have no idea for now since they are usually working without issues after installation expecially on Window.
Is it your first time to install BARAM? If not, has it worked on other machine?
Have you changed any parameters such as installation path during installation?
Could you let me know current installtion path?
Do you have any other MPI packages other than MS-MPI on your Window?
Let's check these first.

Thank you for the response. The issue is resolved. It turned out that I needed to change the order of the paths in the Path variable. After I moved the MS-MPI path to the top of the list, everything started working.
Glad to hear the issue has been resolved!
Feel free to reach out if you run into any other problems while using BARAM.
By the way, do you use any MPI systems on Windows other than MS-MPI?
If so, do you prefer them over MS-MPI?
I’m asking because I’d like to consider supporting other systems if they are widely used.
Thank you.

Microsoft MPI is the primary solution for parallel computing tasks. However, alternative MPI implementations have also been installed to facilitate testing and debugging of third-party code. To make the system more user-friendly, it would be helpful to display clear error messages that explain what went wrong when a problem occurs. Another potential issue relates to number formatting. In some regions, a comma is used as the decimal separator instead of a dot. This can cause errors when entering numbers in specific fields. While this can be fixed by adjusting the system settings, it might be better to add a simple check in the code (like converting commas to dots) to handle this automatically and avoid confusion."
Hi Konstantin,
Thank you for the suggestion.
I will check and update it if I can reproduce the situation.
Could you let me know which MPI system you have installed on you Windows system other than MS-MPI?
When it comes to the commas and dots, converting commas to dots seems good idea.
I will check the feasibility of implementation too.

Hi Jake,
Intel MPI was installed with some software.
I'm having a similar problem but only with BaramFlow. It shows up momentarily on task manager as a 'background process' before disappearing and nothing appears even after a minute of waiting. I've ensure MS-MPI path is placed at the top of the list yet it doesn't resolve the problem.
What I believe could be somehow a cause is the fact that on my initial installation I accidentally set my E drive itself as the directory for installation instead of a dedicated Baram folder but after installing it like this I reinstalled it properly on a dedicated folder. The only reason I suspect this could be somehow an issue is I installed Baram on a separate device (windows laptop) and installed it on a folder the first run and BaramMesh and BaramFlow both worked without problems.
After the reinstallation both Baram programs ran fine and I was able to use BaramFlow to run a tutorial. Yet after making my own custom mesh and exporting directly to BaramFlow from BaramMesh it was stuck on 'copying files' for a few hours before a force shut BaraMesh. From this point BaramFlow wouldn't open and if I tried to export from BaramMesh straight to BaramFlow it would just take me to the BaramMesh case selection page.
If it helps, I've ran openFOAM the standard way by itself on my computer (problematic device) but never on the laptop (device where BaramFlow is running fine).
Hi Ilya,
I'm not sure what causes the issue. The temporary installation should not interfere with the new installation.
Yet I'd like you to try one thing.
Delete these two folders in your user folder, which is usally in c:Users\<username>.
.BaramFlow and .BaramMesh
And run the app(BARAM Flow or BARAM Mesh) again.

Same problem, how to solve it.
