ANSYS Professional NLT

Ever required to take in to account of thermal behaviour in your structural analysis? Most structures that operat under a wide temperature range can be induced with significant levels of thermal stress due to thermal expansion behaviour of the material, if left unchecked, the thermal stress may in turn impact its load bearing capability and life cycle.

ANSYS Professional NLT is the ideal tool for analysing thermal - mechanical coupling, with dedicated thermal analysis capabilities that is unmatched by its sibling products like the ANSYS Professional NLS and ANSYS DesignSpace.

Unique Capabilities

ANSYS Professional NLT offers the following unique thermal capabilities in addition to the complete set of linear analysis capabilities and limited nonlinear analysis capabilities. The capabilities of NLT that differentiates itself from its sibling products are

  • Transient thermal analysis
  • Thermal conduction, convection and radiation
  • Phase change (solid - liquid - gas)

In addition, ANSYS Professional NLT offers the user abundant capabilities in the dynamics arena, with modal analysis and mode superposition spectrum, PSD, harmonic and transient analyses.

Thermal

With ANSYS Professional NLT, the user can simulate the temperature change of the structure/product over dynamically varying temperature environments (i.e a transient thermal analysis). Based on the results from the temperature profile and heat flux profile, the user is equipped with the information to improve the thermal handling capability of the structure by treating high thermal spots or attenuate thermal variation via placing radiation fins at optimal locations or enlarging convection surfaces.

Thermal - mechanical

With ANSYS Professional NLT, it is easy to conduct multi-disciplinary analysis across the thermal - mechanical field. The thermal modules are seamlessly integrated with the structural modules to facilitate the coupled solution. The temperature profile from the thermal module is transferred to the structural module, and based on the temperature field and the material thermal expansion coefficient, the thermal load is calculated in the background. The resulting stress and strain from the analysis will aid the designer in improving the load handling capability of the structure as well as prolonging the life cycle.
