Maximum Stored Number of Neighbors

When more than Nneigh neighbors are found within the security distance, the program retains the only Nneigh closest points and decreases the value of ${\alpha }_{sort}$ .

If all true neighbors lying inside the influence sphere of all particles are still retained, then the results do not change.

In the other case, a message such as "Warning SPH Computation" is sent to the Radioss output file. Note that in the case of such a message, the computation time increases since it becomes necessary to sort closest particles at each cycle. Moreover, this kind of situation has to be analyzed carefully since it is often put into an evidence (local) instability.
