  • ANSYS APDL 基础

    Notes on "ANSYS Mechanical APDL Basic Analysis Guide"

    Chater 1 : Getting Started

    1.1. Building the Model

    Fisrt specify a jobname and analysis title, then use PREP7 preprocessor to define the element types, element real constants, material preperties, and the model geometry.

    1.1.1 Specifying a Jobname and Analysis Title

    Defining the Jobname : /FILNAME command. when the Key argument is set to 1, ANSYS would start new files.

    Defining an Analysis Title : /TITLE command, /STITLE command add subtitles which appear in the output but not in graphic displays

    Defining Units : /UNITS command, serves as a record for subsequent reviews of the analysis

    1.1.2 Defining Element Types

    Must be in PREP7 (use /PREP7) to define element types, use ET command to define the element type by name and give the element a type reference number.

    When defining the actual elements, just point to the appropriate type reference number via the TYPE command

    Example : 

    ET, 1, BEAM188

    ET, 2, SHELL181

    Specify the key options via the KEYOPT command

    1.1.3 Creating Cross Sections

    when using beams or shells , issue the SECTYPE, SECDATA, etc to define cross sections

    when using line and area elements that require geometry data such as cross-sectional area and thickness to be specified as sections, verify via /ESHAPE and EPLOT

    1.1.4 Defining Element Real Constans

    Specify real constans via the R family of commands (R, RMODIF)

    the table of reference number versus real constants set is called the real constant table

    To verify the constant inout, issue the RLIST and ELIST commands

    RLIST lists all real constants sets

    ELIST,,,,,1 shows the real constant labels and their values for each element.

    1.1.5 Defining Material Properties

    each set of material properties has a material reference number, the table of material reference numbers versus material property sets is called material table

    use the MAT command to define the elements

    1.1.6 Creating the Model Geometry

    1.2 Applying Loads and Obtaining the Solution
