The btBvhTriangleMeshShape is a static-triangle mesh shape, it can only be used for fixed/non-moving objects.
If you required moving concave triangle meshes, it is recommended to perform convex decomposition using HACD, see Bullet/Demos/ConvexDecompositionDemo. Alternatively, you can use btGimpactMeshShape for moving concave triangle meshes. btBvhTriangleMeshShape has several optimizations, such as bounding volume hierarchy and cache friendly traversal for PlayStation 3 Cell SPU. It is recommended to enable useQuantizedAabbCompression for better memory usage. It takes a triangle mesh as input, for example a btTriangleMesh or btTriangleIndexVertexArray. The btBvhTriangleMeshShape class allows for triangle mesh deformations by a refit or partialRefit method. Instead of building the bounding volume hierarchy acceleration structure, it is also possible to serialize (save) and deserialize (load) the structure from disk. See Demos\ConcaveDemo\ConcavePhysicsDemo.cpp for an example.
