Partitioning Tetrahedral mesh using Metis-5.0.2

Hi Friends

We have a tetrahedral mesh file with the format where node1 node2 node3 node4 contain the nodal values of each tetrahedral element of the mesh

no-of-elements 3

node1 node2 node3 node4
.
.
.
.

till no-of-elements

when i ran the metis mesh partitioning tool "mpmetis tet.mesh 5" for 5 partitions,

it gave a error:-

"mesh with more than one balancing constraints are not supported yet"

I used the version metis-5.0.2.

Pls help me solve this problem
