Results in SCIA Engineer 15
3D Stress / Displacement - extension
SCIA Engineer 15 comes with extension of 3D Stresses and 3D Displacements functionality in the Results service. This extension consists of three parts:
- correct display of results also on 1D members with openings.
- the same feature for 2D members - the values have been increased by membrane stress and stress components typical for 2D members.
- display of 3D results for ribs.
All this together provides a unique possibility to see 1D and 2D results together in one view. Engineers can display global deformed structure and obtain clear view of the behaviour of the structure.
SCIA Engineer 15 offers possibility to use hot-keys for a set of most common commands:
- Ctrl + C to copy selected objects
- Ctrl + X to move selected objects
- Ctrl + Z to undo action
- Ctrl + Y to redo action
- Enter / Space - to repeat the last command
Extension of 2D results for Open Design
The possibility to display results for 2D members calculated via Open Design have been extended. Now it is possible to use averaging strips (see the picture below - option: redistribution of peak) and show results on edges and along selected sections.
As well as in standard results, there is possibility to use averaging strips. These strips have to be defined in advance (e.g. in Results service). Redistribution of the peaks can be used for any value calculated via Open Design. This gives users the opportunity to eliminate problems due to singularity (nodal support for slab, slab supported with column,...).
Open Design brings a unique possibility to display values calculated via Open Design on selected sections or on edges of 2D member. The user can select:
- diagram type (none, precise, trapezoidal),
- diagram position (section or element plane),
- either total or average values,
- units in drawing.
A brand new feature is a choice of section on a 2D member. The user can select just one or several sections by clicking in the 3D scene or via the selection command (each section has its own name). Moreover, there is a possibility to see the detailed output from Open Design for a selected section.
Updated solver dialogue & new type of solver for eigenvalue problems
Solver settings have been updated. The type of eigen value solver was moved from the general part to dynamics and stability. It is possible to select different eigen value solver for dynamics and stability as can be seen from the attached figure.
A new type of solver for eigenvalue problems have been introduced in SCIA Engineer 15. It is called polynomial method. The related well-known theory can be found in numerous technical books or on the internet. The usage of this method can lead to the shorter time of calculation in comparison to the Lancosz method. The polynomial method is recommended for eigen value problems in dynamics.
SCIA Engineer 15 comes with a brand new development related to non-linear calculations. This non-linearity lies in the behaviour of material. SCIA Engineer 15 implements a new type of material behaviour for 2D members: plasticity. The plastic zone is based on the Von Mieses yield condition (J2 plasticity condition). The yielding condition is:
This calculation can be useful for users dealing with steel pressure vessels and also other analyses that require to take into account the plastic (non-nlinear) material behaviour.
