Defining Pattern Heat Fluxes

You can specify the laser and heat energy parameters that control how the heat used in additive manufacturing is distributed.

Note:

The steps below are based on use of the default (Built-in) schema that is embedded in the app. You can use a custom schema instead by choosing User defined as the source. A custom schema redefines the interface (dialog box) to work with a user subroutine that exposes only the options required for your process. In this case, your options might be different from those described.

Before you begin: To understand the entries and definitions required, review the Abaqus user subroutines and keywords for use with additive manufacturing. Moving heat flux is tied to the UMDFLUX user subroutine.

  1. From the Additive Manufacturing section of the action bar, click Pattern Heat Flux .
  2. Select the part.

    The part indicates the predefined volume (part or mesh) that is filled with material, layer by layer, to become a real part as the additive manufacturing process is completed.

  3. Edit the heat absorption coefficient data in the table.

    The flux absorption coefficient must be between 0 and 1; it defines the percentage of power from the heat source that is absorbed by the part.

    You can include temperature dependence.

    Tip: You can either enter the data directly or right-click a cell to import data.
