1, Meshsize: the mesh size will affect the accuracy of the analysis results and the calculation time. Generally speaking, the smaller the grid, the more accurate the analysis result, but the longer the calculation time. In the process of analyzing AutoFormSigma, the mesh size can be changed by thinning the mesh.

2. Time step: Time step refers to the time interval in the analysis process, which can also affect the accuracy of the analysis results and the calculation time. The smaller the time step, the more accurate the analysis result, but the longer the calculation time. In general, the time step should be small to ensure the accuracy of the simulation.

3. Rheological parameters of materials: Rheological parameters of materials refer to the deformation behavior of materials in the forming process, including stress-strain curves and anisotropy coefficients. The setting of these parameters will affect the accuracy and stability of the analysis results. In AutoFormSigma, you can choose to use the standard rheological parameters of materials, or you can use custom parameters to meet different analysis requirements.

4. Friction coefficient: Friction coefficient refers to the friction coefficient between the workpiece and the die, which will affect the accuracy of the analysis results and the calculation time. The smaller the friction coefficient, the more accurate the analysis result, but the longer the calculation time. In AutoFormSigma, you can choose to use standard friction coefficient or user-defined parameters to meet the analysis requirements.

AutoFormSigma also has other operation setting options, such as strain rate and stress balance. In the process of use, we should choose the appropriate operation settings according to the specific analysis requirements and the limitation of computing resources.
