At the end of the 1970 s and the early 1980 s this programme showed the highly non linear elastoviscous behaviour of salt rock. From the 1980 s, 2D software allowed the sizing of isolated or network caverns and from the 1990 s, 3D software permitted the sizing of any cavity as well as the prediction of changes in cavity geometry during operation. 

A further important property which may be shown by a non-Newtonian fluid is elasticity-which causes the fluid to try to regain its former condition as soon as the stress is removed. Again, the material is showing some of the characteristics of both a solid and a liquid. An ideal (Newtonian) liquid is one in which the stress is proportional to the rate of shear (or rate of strain). On the other hand, for an ideal solid (obeying Hooke s Law) the stress is proportional to the strain. A fluid showing elastic behaviour is termed viscoelastic or elastoviscous.
