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.

Submit a SimSolid Run

Define and run a quick analysis using the Quick run tool.

Complete the model setup before submitting a job for analysis. Analysis is performed in the run folder based on user preferences under Run Options.

In the Tool Deflection ribbon, click the Submit job for quick analysis icon in Quick in the Run group.



The SimSolid run starts and the Analysis Run Status window opens.

After the analysis is complete, the status is updated.

Post-Processing

Use the Show Analysis Results tool to view the results of an analysis in the Analysis Explorer. View and animate results, add callouts, and compare results from different runs.

Results must be available before attempting post-processing.

Click the Analysis Results icon in Quick.



Post-processing mode is activated.

Limitations

Limitations for SimSolid versus OptiStruct analysis include:

  • Constraints at a point must be fixed so that there is no translation or rotation in any direction.
  • Loads must be applied on the necessary surfaces using BCs tool.
  • All runs are local sequential.
  • There is no run history.
  • Undo does not work on deleted results.

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.
Pressure Type
Preferred option for pressure type is Linear or Mapped.
Constant. This option is used when user manually selects the load surfaces and specifies a constant pressure load on each of these surfaces. In this case, automatic detection of load surfaces will be disabled.
Linear. Load surfaces will be automatically detected and you will not have to manually select them. Enter the value maximum load that will occur at billet dummy block interface. Based on this value, loads will be automatically determined using linear interpolation. This assumes 20% of the pressure drop occurs inside the container (at maximum load) and 80% occurs in the die. Interpolation is based on the Z coordinate (extrusion axis).
Mapped. Load surfaces are automatically detected and you will not have to manually select them. Loads are used based on the values computed in the extrusion analysis and are accessed from the *.HMASCII file containing the loads. This file is automatically created by the HX solver. This file should be available in the folder where the model is saved.
Combined Loads. You can also combine mapped or linear pressure types along with user-specified loads. On selected surfaces, you can specify loads manually and also use this feature to override the mapped loads on those faces.
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.
Mesh Order
Second order mesh gives more accurate results, but at the cost of computational time. First order mesh is the recommended option.
Analysis Type
Elastic Deformation within elastic limit. Reforms to original shape.
Elasto-Plastic Deformation beyond elastic limit.
Tool Temperature
Uniform Use average temperature.
Compute Apply temperatures from Heat Transfer Boundary Data to estimate.
Heat Transfer Boundary Data
Specify the Die Ring Temperature and the Backer/Bolster Temperature to compute tool temperature.

Start from Existing Mesh

  1. Click Existing under Mesh Size options.
  2. Enter the path to the mesh file or browse to it.
    Note:

    Supported data formats:

    *.fem and *.bdf

    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.

  3. Click Run to start the job.

Submitting Temperature Dependent Elasto-Plastic Analysis

For an elasto-plastic analysis with temperature-dependent properties, select a tool material with stress/strain curves for each temperature. Creating and selecting this tool material is explained in the Selecting Materials section.

  1. Select Elasto-Plastic under Analysis Type.
  2. Under Tool Temperature, select Uniform or Compute.
  3. Optional: If you select Compute, enter values under Heat Transfer Boundary Data for Die Ring Temp and Backer/Bolster Temp.
  4. Click Run.
