ANSYS TAS - Summary of Features

ANSYS® TAS™

List of Features

Steady state and transient analysis
Two dimensional plate elements

Elements can be four or three sided
Thermal conductivity, thickness, density and specific heat is defined in the property table
Anisotropic thermal conductivity, (different in X and Y directions based on user defined coordinate system)
Thermal conductivity, density and specific heat can be temperature, temperature difference, time and time cyclic dependent
Plate elements can be generated using the automesher using DXF or TAS element geometry
Plate elements can be extruded into three dimensional brick elements
Plate elements can be generated from the face of brick elements
Plate elements can be generated by either selecting the four (or three) corner nodes or by selecting the two diagonal nodes

Three dimensional brick elements

Elements can be six or five sided
Thermal conductivity, density and specific heat is defined in the property table
Anisotropic thermal conductivity, (different in the X,Y and Z directions based on user defined coordinate system)
Thermal conductivity, density and specific heat can be temperature, temperature difference, time and time cyclic dependent
Brick elements can be generated by either selecting the eight (or six) corner nodes or by selecting the two diagonal nodes

Three dimensional tetrahedron elements

Thermal conductivity, density and specific heat is defined in the property table
Thermal conductivity, density and specific heat can be temperature, temperature difference, time and time cyclic dependent
Anisotropic thermal conductivity, (different in the X,Y and Z directions based on user defined coordinate system)

SyncroMesh to thermally attached parts of the model that are meshed differently
Simple to use 2D automeshing
Three types of radiation elements can be generated, node-to-node, node-to-surface and surface-to-surface. The elements can reference the property table where emissivity and view factor are defined. Emissivity and view factor can be time or temperature dependent The TRASYS thermal radiation software is included with TAS used to generate Surface-to-Surface radiation elements accounting for view factors, shadowing and different emissivities.
Convection elements can be generated from a plate element, the face of a brick or tetrahedron to a single node. The heat transfer coefficient is defined in the property table and can be temperature, temperature difference, time or time cyclic dependent. Empirical formulas are included in TAS to calculate heat transfer coefficient. A fluid library is included with temperature dependent properties.
Scalar resistor elements can be generated between any two nodes.
Fluid flow elements can be generated to account for the fluid temperature rise.
Nodal, surface and volumetric heat loads can be fixed or temperature, temperature difference, time or time cyclic dependent
Boundary or fixed temperature nodes can be defined. They can be time or time cyclic dependent.
On/Off and proportional thermostat can control heat loads, convective heat transfer coefficients and resistances. On/Off thermostat has hysteresis.
Mass Transport feature to simulate a moving material.
Simulation of one-dimension subliming ablation.
Two way interface with ANSYS.
OpenGL and GDI graphics supported.
Documentation on the model can be saved with the model.
Coordinate systems can be user defined and used to define thermal conductivity orientation or in the generation of elements.
Any consistent units can be used, Degrees C, F or absolute can be used.
Materials can be selected from a material library.
Models can be solved interactively.
Model is shown three dimensionally on the screen using colors to represent element type, properties and temperatures.
Screen view can be windowed, panned or zoomed manually or dynamically.
Groups of elements can be defined.
Three dimensional color contour plots can be view on the screen.
Hidden line and property plots can be viewed on the screen.
Model outline can be viewed.
Transient results can be plotted using a built in routine and animated (AVI files can be saved, put them right into your PowerPoint presentation).
Screen images can be printed using the standard Windows print dialog box.
Element information can be queried and displayed.
Transient plot data can be saved to disk separately.
Models can be merged.
Both SINDA/G and SINDA/FLUINT models can be created by TAS. FORTRAN generated in the OUTPUT block creates both steady state and transient TAS compatible results files allowing TAS to used as a Pre and Post processor for SINDA.
TAS contains a complete interface with FEMAP

FEMAP neutral files can be read by TAS and converted into TAS models
FEMAP neutral files can be generated by TAS
TAS steady state and transient results can be converted into FEMAP neutral files to be read by FEMAP

Two way interface with MSC/NASTRAN
Input CAD 2D and 3D DXF files
TRASYS radiation models can be created. TRASYS results can be loaded back into TAS to automatically generate surface-to-surface radiation elements. Both steady state and transient cases are supported.
