Experimenting

Experimenting by Adit:

    When the Blast Pressure increase the area of flat surfaces decreases, simultaneously Concave happens, the Center of the Concave moves against the direction of the closest vector of pressure.

Experimenting by Gabrielle:

    When the Blast Pressure increases, four faces come out of every mesh cell, the lower two faces act like protectors of the other two, the joint point between the four faces moves away from the center of explosion according to the pressure. (inspired by examples of Geco)
