DESCRIPTION

Postprocessors can be used to calculate derived quantities from previously computed fields over the domain. Force and heat fluxes postprocessors are enabled in the boundary condition menu. OPTIONS

1 Local shear-rate

For flow problems, the local shear-rate = is computed where D is the rate of deformation tensor

2 Viscosity

For flow problems, the viscosity (function of the second invariant of the rate of deformation tensor, and/or of the temperature) is produced

3 Rate of deformation tensor

For flow problems, the components of the tensor D are computed

4 Inelastic stress tensor

For generalized Newtonian flow problems, the components of the stress tensor T are computed

5 Viscous heating

For flow problems, the viscous heating is computed

6 Total extra stress tensor

Some viscoelastic models include a purely viscous counterpart to the stress tensor. For such models, the knowledge of the total stress tensor is of interest. Selecting this option produces this total stress tensor.

7 Residence time

For flow problems, the residence time distribution is computed

8 Tracking of material points

For transient simulations only, this postprocessor allows for the tracking of x=constant, y=constant (and z=constant) lines (planes) through the flow domain.

9 Tracking of a material property

For flow problems, the user can track particles by assigning a value of a 'material property' (a scalar field) to them and following the advection of this property in the flow domain.

10 Forces on slices

For axisymmetric fiber spinning problems, computes the force acting on each slice of the mesh.

11 Heat fluxes

Computes the heat fluxes

12 Flow rate

Computes the flow rate

13 Joule effect

Computes the Joule effect = s/2 —v•—v

14 Mixing index

Computes the mixing index = /(+)

15 Extension evaluation

Computes the extension (linear and area strech) of material in Blow molding or Thermoforming simulations..
Available for shell models only.

16 Vorticity

Computes the rotational of the velocity vector on the flow domain.

17 Convected heat

Computes the integral of ro Cp V.n T on a boundary set specified by the user.

NOTES For viscoelastic flows with a purely viscous component, the calculation of the total stress tensor will be performed upon request. SEE ALSO
