    Hi,

    Isolid = 14 is for 8-node linear element with various number of integration points, and has co-rotational formulation.  When more integration points are used it could be computationally expensive, but will produce accurate results with no hourglass. 

    Whereas for Isolid=17 it has only standard integration.

    We recommend to use Isolid=24. under-integrated elements but with physical hourglass stabilization, and the computation time will be also less.

    Please go through RADIOSS theory manual in Help menu where these element formulations are shown.
