Function gmsh_sys::gmshModelMeshGetBarycenters

pub unsafe extern "C" fn gmshModelMeshGetBarycenters(
    elementType: c_int, 
    tag: c_int, 
    fast: c_int, 
    primary: c_int, 
    barycenters: *mut *mut f64,

)

Get the barycenters of all elements of type elementType classified on the entity of tag tag. If primary is set, only the primary nodes of the elements are taken into account for the barycenter calculation. If fast is set, the function returns the sum of the primary node coordinates (without normalizing by the number of nodes). If tag < 0, get the barycenters for all entities. If numTasks > 1, only compute and return the part of the data indexed by task.
