Batch processing through scripting appeared in CFD-VisCART v2006 and this feature kept improving since then. You can see a short description in this past user tip. This can be very useful to create meshes without graphical interaction or to set up similar models over and over. Since CFD-VisCART v2009, a new feature will make its use even easier and powerful: You will now be able to dump a batch script from an existing VGD file.

After loading a pre-set vgd file in CFD-VisCART graphical interface, or creating one, you can now output a script file automatically with all the commands needed to recreate this same VGD file in batch mode.
The main advantage obviously is the ability to easily create script files for similar models. After setting up one model, you can dump one script, and modify it for all your similar models. Parameters, such as mesh sizes, components, mesh sources…, can be modified and adapted.

Another advantage of this feature is that you don’t need to know the batch script commands to write the scripts you need. You can simply set up a vgd file as you would normally do in the graphical window and then dump a script that you can reuse, without knowing any scripting commands

You can use this feature from the File menu (Figure 1) or the Toolbar (Figure 2).

After clicking on the Dump Script icon, a file saving dialog button will appear to specify the dump script file. The Default extension is .vbt (CFD-VisCART batch text file), but you can specify any name and extension you would like.

If you have any questions about this feature or would like us to discuss some other topic in the future, please let us know.
