You d Y do not t need d to t tell t ll ANSYS th the system t of f units it you are using. i Simply decide what units you will use, then make sure all of your input is consistent.
– For example, if the model geometry is in inches, make sure that all other input data — material properties, real constants, loads, etc. — are in terms of inches.
• •
ANSYS does NOT do units conversion! It simply accepts all numbers you input without questioning their validity. The command /UNITS allows you to specify a units system, but it is simply a recording device to let other users of your model know what units you used.

Using the Material Library • • This method allows you to choose a predefined set of properties for a given material.

INTRO ODUCTIO ON TO AN NSYS - Part P 1
ANSYS supplies typical structural and thermal properties (linear only) for some common materials, materials but we strongly recommend that you create your own material library. To choose a material from the library:
– First define the library yp path. • Main Menu > Preprocessor > Material Props > Material Library > Library Path – Enter the location from which to READ material data, e.g, \v100\ANSYS\matlib. • Or use the /MPLIB command.

– Then “import” a material from the library. • Main Menu > Preprocessor > Material Library > Import Library – Choose the units system. This is used only to filter the list of files shown in the subsequent dialog. ANSYS has no knowledge of units and does NOT do unit conversion. conversion – Choose the desired material file, such as steel AISI C1020. • Or use the MPREAD command with the LIB option option.

Specifying Individual Material Properties • • Instead of choosing a material name, name this method involves directly specifying the required properties through the Material Model GUI. To specify individual properties: – Main Menu > Preprocessor > Material Props > Material Models • Double-click on the appropriate property to be defined.
