Submitting a Job

Define and run an analyis using the Run Analysis tool.

The model setup should be completed before submitting job for analysis. Save the model in a new folder with the desired project name. Analysis will be performed in this folder based on user preference under Run Options.

  1. Click on the Analysis tool in the Run group.
  2. In the Analysis Parameters dialog, define parameters accordingly.
  3. Click Run to submit the job.
    The status of the run is displayed.
  4. Click Export to complete the pre-processing.
    The process stops after the data decks for the solver are generated.

Analysis Parameters Settings

Project Name
The data deck is written with "name" as a prefix. It is written in the same folder where the model is saved. Avoid using special characters as files will be created using this name.
Profile Temp
Exit temperature of the profile after extrusion. This is the temperature at die exit. Typical values are around 525° C.
Note: If you select Map Extrusion Results, that profile temperature will override whatever is given here.
Puller Speed
The speed at which the puller pulls the profile. Typically, this is similar to extrusion speed (ram speed × extrusion ratio).
Simulation Time
The time required by the profile to exit the last quench zone. This is the recommended value to see the complete quenching analysis.
Time Step Size
The recommended value is 1 second. Reduce this value if you want a more detailed temperature history. Reducing this value will increase the CPU time, as the number of steps is the ratio of simulation time to time step size.
Warpage Analysis
Check this box to perform Warpage Analysis.
Mesh Size
Medium is the preferred option. If the model has many fine features, selecting fine is recommended. If it is a simple model, coarse option can be used. To start from existing mesh, click on Existing and select the mesh file. To specify mesh size by part, click on User-defined, then click the Mesh size tab and adjust default mesh sizes.
Map Extrusion Results
Check this box to consider the profile temperature and grain size from a previous extrusion analysis in the quenching simulation. Browse to that run's directory to select it.
Stationary Profile Analysis
Check this box to keep the profile stationary, which provides greater precision in quenching and control over the cooling rate.
Advanced Tab
The Advanced tab provides access to expert-level options for the solver.
Specify User Defined Functions: Use this section to incorporate custom material models or grain prediction models via user-defined dynamic link libraries (DLLs). For more information on integrating user-defined functions, refer to the advanced training packet.
  • Select DLL: Provide the path to the DLL file. Sample DLLs are available at: <Installation Folder>\Altair\2026\hwsolvers\hx\lib\win64.
  • Select Function: Choose the specific function within the DLL to use.
  • Select Type: Specify whether the DLL is for a Material or Grain Size.
User Commands - Before Loading GRF: Use this field to override the default solver parameters before loading the GRF file. Enter pset parameters directly in the text box.
User Commands - After Loading GRF: Use this field to override the default solver parameters after loading the GRF file. Enter pset parameters directly in the text box.
For a list of supported pset variables, refer to What are Key pset Solver Variables?.

Start from Existing Mesh

Start from an existing mesh in Advanced Mesh Controls.

  1. Enter the path to the mesh file or browse to it.
    Note:

    Supported data formats:

    *.grf, *.bdf, and *.fem

    Specifications:

    1. The length unit of mesh must be the same as the user unit.
    2. The meshed part name should be the same as the solid part name, with optional suffix "3D". For example, if the solid part name is DiePlate, then choices for meshed part names would be DiePlate3D or DiePlate.
  2. Click Run to start the job.

User-Defined Mesh Controls

Define mesh size controls by part.

Under Mesh Type, click User-Defined to open the Mesh Size Controls table.

The table lists each part of the model, its type, volume, and surface. You can edit the volume value for each part.
