https://azuremarketplace.microsoft.com/en-us/marketplace/apps/nextfoam.nextfoam_baram24_ubuntu_x86?tab=Overview

Start

On Windows, BaramFlow and BaramMesh icons are created on the desktop after the program installation is complete. Double-click the icons to run them.

On Linux, use the terminal to run the file. In the terminal, navigate to the folder where BARAM is installed and run the file to start the program. The executable file is a bash script and the command is as follows.

BaramFlow : baramFlow.sh or python -m baramFlow.main
BaramMesh : baramMesh.sh or python -m baramMesh.main

When you run BaramMesh, a window appears where you can choose whether to run a new project or open an existing project.

Start Window

The window displays the folders that have been recently used, which you can select to start BaramMesh and open the project. If you want to open an existing project and it is not displayed in the window, you can select the folder by pressing the Open button.

To start a new project, click the New Case button and enter the name in the desired location.

Main Window

When you run the program, you'll see a window of figure.

Main Window

The main window can be divided into six areas

Menu
Progress panel : The part at the top of the screen that shows each steps
Configration window : Setup conditions for each step
Display Control : Located in the second left corner of the screen. Settings for the display of geometry and grids
Graphic window : Show geometry and mesh
Console Log : shows messages, error statements and more as the mesh generation progresses

There are menus for File, Mesh Quality, View, Parallel, Settings, Help.

File

In file there are sub-menus as New, Open, Open Recent, Save, Exit.

Mesh Quality

Clicking on Mesh Quality will bring up the window shown below. The mesh will be created based on the values set here.

Mesh Quality parameter

Parallel

Make settings for parallel computation. Select the number of CPU cores and parallel computation method. There are Local Machine and Cluster.

Parallel setup window

In the case of Cluster, you need a text file with the node list. The View/Edit button lets you type directly or load a file. The contents of the file are as follows:

[node name1]   cpu=[number of cores]
[node name2]   cpu=[number of cores]
[node name3]   cpu=[number of cores]
...

Settings

Scale : This adjusts the program's resolution, and anything higher than the default of 1.0 will result in larger windows and larger text. You must close and restart the program for the new settings to take effect.
Language : Currently, only English, Suomi (Finnish), and Korean are supported. Language translation is done using Qt Linguist. Anyone can contribute translations. https://baramcfd.org/docs/internationalization

Progress panel

Seven steps are shown. The next step is currently disabled. When you finish the current step and press the Next button, the current step is locked and the next step is enabled.

If you go back to a previous step, you can see its status, but you can't edit it. If you want to edit the previous step, you must unlock it by pressing the Unlock button. Unlocking unlocks all subsequent steps and clears the mesh data that was created.

Configration Window

Set models and values for each step.

Display Control

You will see a list of geometries and mesh. There are three types: Geomerty, Boundary, and Mesh. In the [1.Geometry] and [2.Region] steps, only Geometry is displayed, and when you create a background grid in [3.Base Grid], Boundary and Mesh appear from then on. You can sort the list by clicking Name and Type.

If you right-click on the list, you will see Hide, Opacity, Color, Display Mode, and No Cut. This is how you can set the display appearance. You can set each item individually, or you can set several at once by dragging the mouse.

Display Control

The on/off button in the display control, is for choosing whether to show the mesh in the graphics window, to avoid the inconvenience of taking a long time to render graphics as you move through the progress steps in case of very large mesh.

Expand 'Cut' at the top to see the Clip and Slice options. Slice allows you to view a section perpendicular to the axis. Objects that have No Cut selected in the Display Options will not be cut.
