+where <m>epsilon</m> is directly evaluated from the velocity field and <m>p</m> is the isotropic pressure.The convention is that a positive stress corresponds to a tensile stress (opposite to the isotropic pressure convention).
 This solver doesn't work for the GOLF anisotropic ([[solvers:aiflow|AIFlow Solver]]) and the snow/firn ([[solvers:porous|Porous Solver]]) rheologies. Nevertheless, these two solvers have intrinsic functions which allow to compute the stress directly.
