get_node_physical_id nrv.fmod.FEM.mesh_creator.get_node_physical_id(id_ax: int, i_node: int, volume: bool = False) → int[source] Compute the physical-domain identifier associated with one myelinated node. Parameters: id_ax (int) – Base physical identifier of the parent axon. i_node (int) – Node index along the axon. volume (bool, optional) – Reserved flag for API compatibility. Returns: Physical identifier assigned to that node. Return type: int
