""" """
Set order in which concurrent sub-meshes should be meshed Set priority of sub-meshes. It works in two ways:
* For sub-meshes with assigned algorithms of same dimension generating mesh of
*several dimensions*, it sets the order in which the sub-meshes are computed.
* For the rest sub-meshes, it sets the order in which the sub-meshes are checked
when looking for meshing parameters to apply to a sub-shape. To impose the
order in which sub-meshes with uni-dimensional algorithms are computed,
call **submesh.Compute()** in a desired order.
Parameters: Parameters:
submeshes: list of lists of :class:`sub-meshes <SMESH.SMESH_subMesh>` submeshes: list of lists of :class:`sub-meshes <SMESH.SMESH_subMesh>`
