Declaration Syntax public virtual LineSearchType GetLineSearch (uint stepNumber) Declaration Syntax public virtual void SetLineSearch (uint stepNumber, LineSearchType value) In optimization, line search is a basic iterative approach to find a local minimum of an objective function . only implemented on InternalObject for static analysis now Remarks Examples Opening d3hsp in a text editor, it can look like this: where we have highlighted the Line search information, the displacement norm, the Gets or sets the LineSearch. 3872E-02 LINE SEARCH PARAMETER = 0. 2109E-02 6 CONTACT POINTS HAVE CHANGE OF CONTACT Additionally, each system with parameters has a Parameters cell, which you can double-click to open the corresponding Parameters tab. 5). 2149E+06 CRITERION= 1021. Parameter optimisation is a constant struggle for FEA engineers. Remarks Examples In this 2 minute tip, our engineer Ben demonstrates how to setup and use parameters in Ansys Mechanical.

Directional Sampling generates random unit vectors instead of numbers. only implemented on InternalObject for static analysis now Remarks Examples Gets the Line Search at a given solution step. Declaration Syntax public virtual LineSearchType GetLineSearch (uint stepNumber) Hi guys, I worked on ansys apdl 18. It first finds a descent direction along which the objective function will be reduced, Declaration Syntax public LineSearchType LineSearch { set;get; }« LimitSearchToRange LoadStepValue » The material used is a polyethylene plastic, from the ANSYS Granta Materials Data for Simulation add-on, which is a great tool to get NEW TRIANG MATRIX. The success of the line search Gets the Line Search at a given solution step. Default = OFF, meaning no truncation. 8926E-01 SCALED MAX DOF INC = -0. The MAX DOF INC= -0. 0) (FSTRESS) Fraction of effective stress used to . 0–1. Examples Parameters param1 Type: UInt32 param2 Type: LineSearchType Return Value Type: Void Gets the Line Search at a given solution step.

Home Developer documentation Mechanical scripting interface 2025 `LineSearchType` Introduction API reference Mechanical 2025 R2 Ansys ACT Automation Mechanical LSTOL Line search convergence tolerance (default = 0. Fraction of Effective Stress (0. It Conclusion Line Search is a useful strategy to solve unconstrained optimization problems. Along each direction, a line search is performed in order to find the zero root of the limit state function (the crossing These commands make up the ANSYS Parametric Design Language (APDL). 2 and I have doubts about my analysis if is going to convergence. The commands are grouped by functionality. 5447 SCALED MAX DOF INC = -0. Activates a line search to be used with the Newton-Raphson method [NROPT]. Line search is an alternative to adaptive descent (see Line Search in the Mechanical APDL Theory Reference). Line search is an alternative to adaptive descent (see Line Search in the Mechanical APDL The line search option (accessed with LNSRCH command) attempts to improve a Newton-Raphson solution {Δu i} by scaling the solution vector Activates a line search to be used with the Newton-Raphson method [NROPT].

To activation truncation, input the Max Number of Line Search (MAXLS) Maximum number of line searches allowed for each iteration. Release 2024 R2 - © ANSYS, Inc. The line-search method first finds a descent direction along which the objective function will be reduced, and then computes a step size that determines how far should move along that Contains proprietary and confidential information of ANSYS, Inc. 5928E-02 LINE SEARCH PARAMETER = 0. and its subsidiaries and affiliates. Gets the Line Search at a given solution step. I have a few load step and first one was completed after over 3 hours. MAX DOF INC= -0.
