This is a 72 frame smoke VDB animation sequence, which I created using special effects software and includes a single frame VDB. You can import it into your engineering software, check to load the VDB sequence and animation, and match your project by adjusting the animation playback speed. You can also directly use the rendering static VDB. I used c4d2023 Arnold rendering, which has no material and you need to adjust it yourself or use the software's built-in smoke material

Note that this VDB project does not have a basic point, line, and surface model, such as fbx/obj/stl. You need to convert it yourself by using VDB to polygon or baking it into a basic point, line, and surface model using plugins. VDB is a special effects project and does not belong to the category of basic models
