How Can I Reduce CPU Time and Get a Quick Solution?

  1. 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.
  2. Adjust element size: When extruding thin profiles, the profile and pocket dimensions are small compared to the weld chamber,. In such cases, we can use larger element sizes (3 to 4 times the element size in bearing/pocket (if it exists). This will reduce the element and node count and hence reduce time spent in solving.
  3. Bias the elements in bearing: This will reduce the element and node count – reduce time spent in solving.
  4. Increase the nonlinear tolerance to 0.01: This will reduce the times solver is called. Can reduce CPU time by 50%. Use this option for model with more than 500,000 nodes/ Bearing optimization/Transient simulation.
