Analysis Extenders
|
This extender adds capabilities for computational fluid dynamics analysis to your core package.
Analysis capabilities include steady-state and transient heat transfer analysis, steady and unsteady fluid flow analysis and mass transfer analysis.
Heat transfer analysis capabilities solve for linear and nonlinear thermal designs by considering conduction,
convection, heat flux, heat generation, radiation and thermal contact in steady-state or transient analyses.
Fluid flow analysis capabilities determine the steady and unsteady flow patterns for incompressible, laminar, Newtonian or non-Newtonian fluid flow designs.
Knowledge of flow rates is optional, since inlet and outlet pressures can be specified instead of flow rates.
This extender also handles turbulence in laminar flow designs.
This feature enables the prediction of turbulent flow (large changes in velocity over small distances)
and laminar flow (smooth, gradual changes in velocity distribution) at the same time in the same model.
Coupled heat transfer and fluid flow analysis capabilities determine the effects of natural, forced or mixed convection.
When this extender is coupled with stress analysis capabilities, it determines the effects of temperature
on mechanical models composed of isotropic or orthotropic materials;
or the effects of stresses generated by fluid flows on containment vessels and/or interior constrictions can be calculated.
When coupled with Mechanical Event Simulation with nonlinear material models, this extender can also determine
creep of an object and the stress incurred as the temperature varies over time.
When coupled with electrostatic analysis capabilities, it determines the effects of Joule heating.
