    Hi,

    The ideal shape for a tetrahedron element is an equilateral tetrahedron. Various quality parameters check how far a given element deviates from the ideal shape. And a similar quality parameter is tetcollapse.

    Tetcollapse is defined as the distance of a node from the opposite face divided by the area of the face multiplied by 1.24.

    Ideal Value of tetcollapse for a tetra element is 1.0 , and value greater that 0.1 is acceptable.
