Laser Engineered Net Shaping (LENS®)

The ADINA Thermal program is used for the solution of heat transfer problems in solids and structures. It has powerful features such as radiation between surfaces of arbitrary geometries, element birth-death options and capabilities for highly nonlinear material behavior.

Temperature field of turbine casing
Temperature field of turbine casing, convection boundary conditions.

ADINA Thermal analysis capabilities include:

dot 2-D & 3-D conduction, convection and radiation.
dot Solids and shell structures.
dot Steady-state and transient conditions.
dot Radiation between arbitrary surfaces.
dot Element birth and death options.
dot Time and temperature-dependent material properties.
dot Automatic time stepping.
dot Electrostatic, seepage and piezo-electric analysis.
dot Latent heat effects, e.g., freezing and melting conditions.
dot Coupling to ADINA Structures.
A unique capability of ADINA Thermal is the analysis of radiation between surfaces. The surfaces can have arbitrary geometries, can be arbitrarily obstructed and radiate upon themselves.

The bottle in this figure was analyzed using this radiation capability.

Thermal analysis for SAW
Thermal analysis for SAW (Submerged Arc Welding), multipass butt weldment.
Welding-induced residual stress analysis requires a reliable nonlinear analysis system with specialized modeling techniques. ADINA Thermal and ADINA Structures are used successfully in welding analysis.
The finite element calculation was performed using the birth/death options of the elements, with material properties highly dependent on temperature.

The solution was obtained using 3 restart runs and 1,500 time steps.
