    How to use existing mesh in Click2Extrude Metal

    Steps: Setup model as in tutorial #1 in training manual Export Parasolid file from Click2Extrude. We will generate mesh using this CAD This makes sure that CAD in C2E is same we are going to use for meshing Mesh the model manually and export as GRF/FEM/BDF Now come back to C2E & Load the Parasolid. Make sure the Geometry components & meshed components match Verify the unit set in C2E is same the incoming mesh In C2E, go to the export panel and select Mesh type as Existing and pick the exported GRF file from step #3.

    How To Simulate Dead Cycle Time?

    Overview Need: Understand heat transfer characteristics during billet loading and upsetting stages Feature: Perform thermal analysis during dead cycle time Compute heat transfer between billet and container/liner Calculates billet temperature at the start of extrusion Benefit: Help design better container heating system to maintain optimum billet temperature Minimize dead cycle time Increase productivity What is Dead Cycle Time? The time between the end of one extrusion cycle and the start of the next cycle Dead cycle time is typically between 15 sec to 20 sec First half is spent in removing the back end of the previous billet Remaining time is for loading and upsetting the new billet During upsetting process, the bottom half of the billet loses heat to the container Creates temperature gradient in the lateral direction Material flows faster in the top half compared to the bottom half Will produce non-uniform flow at the die exit The important factor to consider while designing container heating system Refer to attached document on how to use this feature: Click2Extrude Metal - How To Simulate Dead Cycle Time.pdf

    How to reduce CPU time and get quick solution

    Geometry cleanup: Merge fixed points that do not significantly alter the geometry (such as very small fillets).This will increase the solver speed. For the same number of equations, the solver spends more time factoring matrices from elements with bad angles. Adjust element size: There are three meshing option fine, Medium, and Coarse. Coarse mesh will run faster. Increase the nonlinear tolerance to 0.01: This will reduce the times solver is called. This can reduce CPU time by 50%. Use this option, If model has more than 4 M elements or 0.5 M Nodes Running Bearing optimization Running Transient simulation
  4. Click2Extrude Metal supports two level of licenses: Standard Advanced Standard Version supports following features: Profile nose cone analysis Seam weld strength prediction Tool deflection analysis Coupled tool deflection analysis with OptiStruct Advanced Version supports following features: All features that are available the standard version Charge weld analysis Backend defects analysis (skin tracking) Automatic ram speed correction based on press tonnage Thermal management & fully coupled analysis* User-defined functions for material data, etc.* Advanced license supports all existing features in the solver, however, some of the advanced features do not have a user interface (for example, last two items in the above list).
  5. Yes. Click2Extrude simulate the material flow inside die cavity and then applies contact forces on to tool surfaces to accurately predict tool deformation and stresses.
  6. Yes. It is possible to add new material. Click2Extrude also allows a user to define material using new constitutive model using User Defined Material as DLL.
  7. Click2Extrude supports direct and indirect extrusion presses.
  8. Click2Extrude helps in predicting extruded profile nosecone, extrusion tool deformation and stresses, predict charge weld length and back end scrap, predict seam weld locations and strength. It also helps in optimizing bearing lengths and ram speed.
  9. Automatic bearing length optimization, predicting die deflection, dummy block failure, container liner expansion, die wear and excessive heating, improper thermal management.
  10. Click2Extrude help in predicting charge weld length, seam weld, billet skin detects uneven grain size distribution.
  11. Visible defects like extruded profile deformation, uneven wall thickness, die pickup lines (streak lines)
  12. Yes. Balancing the die by fine tuning the bearing lengths manually and iteratively in production can be time consuming and expensive. Click2Extrude Metal automatically optimizes the die with leading numerical methods in a single set up.
  13. No. Click2Extrude offers just one package with access to all features.

    Which platforms does Click2Extrude run on?

    Interface support Windows 64 bit. The solver supports both - Windows and Linux If the user is involved with many large and complex dies, then Click2Extrude also has the ability to perform simulations on a big Linux machine. In this scenario, the user will work on light configuration windows desktop which is used for model setup then Click2Extrude launches simulations on large Linux cluster seamlessly.
