ANSYS/EDŽ Programs - a family of ANSYS/Multiphysics educational programs which can be used as personal training tools in industry, at universities and other academic institutions, and at home. The ANSYS/ED programs are similar to ANSYS/Multiphysics in that they contain virtually all of the features of ANSYS/Multiphysics and use the same GUI, but they contain limits for the size of the model that can be created and solved. Limits are included for the following programs:
ANSYS/ED FEA Limits |
|
| Maximum DOF | 2,000 (14,000 for FLOTRAN) |
| Maximum Node Number | 1,000 (2,000 for FLOTRAN) |
| Maximum Element Number | 500 (2,000 for FLOTRAN) |

ANSYS Features Demonstrated - Lists the noteworthy features demonstrated in the problem.
Analysis Options - Typical analysis options are the method of solution, stress stiffening on or off, and Newton-Raphson options for nonlinearities.
Analysis Type - Any of seven analysis types offered in ANSYS: static, modal, harmonic, transient, spectrum, eigenvalue buckling, and substructuring. Whether the problem is linear or nonlinear will be identified here.
Applicable ANSYS Products - Indicates which ANSYS programs can be used to run the example problem. Applicable products are determined by the discipline and complexity of the problem. Possibilities include: ANSYS/Multiphysics, ANSYS/Mechanical, ANSYS/Structural, ANSYS/LS-DYNA, ANSYS/LinearPlus, ANSYS/Thermal, ANSYS/Emag, ANSYS/FLOTRAN, ANSYS/PrepPost, ANSYS/ED.
Boolean Operations - (based on Boolean algebra) provide a means of combining sets of data using such logical operators as add, subtract, intersect, etc. There are Boolean operations available for volume, area, and line solid model entities.
Direct Element Generation - defining an element by defining nodes directly.
Discipline - Any of five physical (engineering) disciplines may be solved by the ANSYS program: structural, thermal, electric, magnetic, and fluid. Note that you can also solve multi-field problems in ANSYS, which consider the effects of the physical phenomena coupled together, such as temperature and displacement in a thermal-stress analysis.
Element Options - Many element types also have additional element options to specify such things as element behavior and assumptions, element results printout options, etc.
Element Types Used - Indicates the element types used in the problem; over 100 element types are available in ANSYS. You choose an element type which characterizes, among other things, the degree-of-freedom set (displacements and/or rotations, temperatures, etc.) the characteristic shape of the element (line, quadrilateral, brick, etc.), whether the element lies in 2-D space or 3-D space, the response of your system, and the accuracy level you're interested in.
Higher-Order Elements - Higher-order, or mid-side noded elements, have a quadratic shape function (instead of linear) to map degree-of-freedom values within the element.
Interactive Time Required - This is an approximate range, in minutes, for you to complete the interactive step-by-step solution. Of course the amount of time it takes you to perform the problem depends on the computer system you use, the amount of network "traffic" on it, the working pace that is comfortable for you, and so on.
Level of Difficulty - Three levels are offered: easy, moderate, and advanced. Although the "advanced" problems are still easy to follow using the interactive step-by-step solution, they include features that are typically thought of as advanced ANSYS capabilities, such as nonlinearities, macros, or advanced postprocessing.
Material Properties - Physical properties of a material such as modulus of elasticity or density that are independent of geometry. Although they are not necessarily tied to the element type, the material properties required to solve the element matrices are listed for each element type for your convenience. Depending on the application, material properties may be linear, nonlinear, and/or anisotropic. As with element types and real constants, you may have multiple material property sets (to correspond with multiple materials) within one analysis. Each set is given a reference number.
Plane Stress - a state of stress in which the normal stress and the shear stresses directed perpendicular to the plane are assumed to be zero.
Postprocessing - ANSYS analysis phase where you review the results of the analysis through graphics displays and tabular listings. The general postprocessor (POST1) is used to review results at one substep (time step) over the entire model. The time-history postprocessor (POST26) is used to review results at specific points in the model over all time steps.
Preferences - The "Preferences" dialog box allows you to choose the desired engineering discipline for context filtering of menu choices. By default, menu choices for all disciplines are shown, with non-applicable choices "dimmed" based on a set of element types in your model. If you prefer not to see the dimmed choices at all, you should turn on filtering. For example, turning on structural filtering completely suppresses all thermal, electromagnetic, and fluid menu topics.
Preprocessing - ANSYS analysis phase where you provide data such as the geometry, materials, and element types to the program.
Primitives - Simple predefined geometric shapes that ANSYS provides. A rectangle primitive, for example defines the following solid model entities in one step: one area, four lines, and four keypoints.
Real Constants - provide additional geometry information for element types whose geometry is not fully defined by its node locations. Typical real constants include shell thicknesses for shell elements and cross-sectional properties for beam elements. All properties required as input for a particular element type are entered as one set of real constants.
Solution - ANSYS analysis phase where you define analysis type and options, apply loads and load options, and initiate the finite element solution. A new, static analysis is the default.
Working Plane (WP) - an imaginary plane with an origin, a 2-D coordinate system (either Cartesian or Polar), a snap increment, and a display grid. It is used to locate solid model entities. By default, the working plane is a Cartesian plane located at the global origin.
