Hello, I can't find in archives a file to practice with the explosion material (with a mesh).
Hi Marfa,
I don't think there is such a file included, but you can download a vdb from for instance:
https://jangafx.com/software/embergen/download/free-vdb-animations/
Near the bottom are the smaller files.
In Blender you can then SHIFT+A > Volume > Import OpenVDB.
