Asymptotic Barenblatt coefficient.
data = [p^{infty}]
Note:
solving “dw_diffusion.i1.Y3( m.K, qc, pc ) = 0” solve, in fact “C p^{infty} = hat{C} hat{pi}” with the result “hat{p^{infty}}”, where the rhs comes from E(P)BC. - it is preferable to computing directly by “hat{p^{infty}} = hat{C^-1 strip(hat{C} hat{pi})}”, as it checks explicitly the rezidual.
Homogenized fading memory Biot-like coefficient.
