Pressure tensor components are recorded during the production run.
These equilibrated boxes at the correct densities were then used as the starting point for several NVT simulations as describe in the methods section to record the pressure tensor components.
We also calculated the viscosities of the all four mixtures at all four pressure points at 150C using EMD simulations and using the Green-Kubo analysis on the recorded pressure tensor components.
ij], the density, thermodynamic pressure, energy vector, and the anisotropic pressure tensor, respectively.
The inflation of this cuff at certain pressures produces signals that will be detected by a high-resolution pressure tensor, and this sends these signals to the computer.
where [sigma], p are the energy density and isotropic pressure, respectively, and P denotes the anisotropic pressure tensor of the fluid, [mu] is the unit timelike vector field, called flow vector field of the fluid associated with the 1-form y given by g(X, [mu]) = [gamma](X) for all X.

Thus, the stress and pressure tensors for the offered system of shells and a sphere inside are obtained.
The given approach allows to receive analytically the values of pressure on the limits and inside the spheres, and also stress and pressure tensors.
