Solver Setup

This setup dialogue provides for adjustment of basic parameters controlling the calculation.

Solver setup is possible to open in two ways. Either in standard project tree in group "Calculation, mesh", or in the dialog "FE analysis" just before the calculation is executed..

Parameters in Solver setup are divided into several groups according analysis type (Nonlinearity, Dynamics...), or as parameters for special functionality (Soil, Mass...).

Solver setup groups of parameters

- General

This group of parameters is available for all type of calculations in the project.

There is only limitation in "type of structure" in "project data" dialog where there is no settings for slabs in for example project type "frame".

Parameters for this group

- Neglect shear force deformation

- Bending theory of plate/shell analysis

- Type of solver

- Number of sections on average member

- Warning when maximal translation is greater than

- Warning when maximal rotation is greater than

More information about these parameters is here : " Obecné parametry výpočtu"
