The Curing Kinetics node defines equation to analyze the evolution of the conversion degree during curing reactions. Define the rate expressions as required.

To specify the velocity field, select the source of the Velocity field. For User defined, enter values or expressions for the velocity components in the input fields. This input option is always available. You can also select the velocity field solved for by a Fluid Flow interface added to the model component. These physics interfaces are available for selection in the Velocity field list.

The following parameters are required for the n-th order model:

The following parameters are required for the Sestak–Berggren model:

The following parameters are required for the Kamal–Sourour model:

A diffusion factor fd is introduced to account for the reaction rate decrease as the conversion reaches the critical value. Select a Reaction rate limiter model: None, Diffusion factor, and Modified diffusion factor.

Use this section to specify the Volume fraction of the cured fluid, Vf. The default is 1.
