Composites processing software (for engineers)

Thermal Modeling Capabilities

COMPROSOFT utilizes a powerful thermal module which can examine anything from simple one dimensional problems to two dimensional transient problems with localized thermal boundary conditions, moving boundary problems, internal heat generation, and even mass transport problems. The general features of the COMPROSOFT Thermal module is:

• Model can facilitate multiple material types (isotropic and anisotropic (composite) materials)
• Modular boundary conditions which include,
• Free convection
• Forced contact problems
• Adiabatic (insulated) walls
• Impinging gas (heating or cooling)
• I.R. radiation, Heat flux, Internal heat Generation
• Moving boundary problems.
• Internal heat generation included.
• Mass transport of domain is included.
• The model can be used for neural network training for optimization purposes.
• Data can be viewed in real time using an external Viewer (Power FORTRAN Module)

At the heart of CPS Thermal module is a 2-D A.D.I. (Alternating direction Implicit) transient thermal solution scheme which is unconditionally stable (not dependent on mesh spacing or time step) and can be used to solve transient problems with a wide range of possibilities.

The governing equation within this module is as follows:

Where V    = Process Velocity [m/s]
           cp    = Specific heat of material [J/Kg K]
           kx , ky = Thermal conductivity [W/m K]
           r     = Mass Density [Kg/m3]

The thermal domain is solved in two steps as follows:

• X-Sweep : X direction is treated implicitly, Y direction is solved explicitly
• Y-Sweep : Y direction is treated implicitly, X direction is solved explicitly
