General
calculation parameters
Any type
of calculation can be controlled by means of a set of parameters.
|
Proper
FEM analysis of cross-section parameters
|
If this option is ON, torsional constant
and shear relaxation are calculated by means of finite element
method for cross-sections defined as (i) general cross-section,
(ii) geometric shapes or (iii) wooden sections.
|
|
Neglect
shear force deformation
|
This setting has effects on beams.
The option ON means
- The shear areas are equal to each other
The option OFF means :
- Shear areas are computed exactly, using numerical integration.
NOTE: With this option ON, you get the same results for internal forces for SE and manual calculation.

| Bending theory of plate/shell analysis |
Defines if Kirchhoff or Mindlin banding theory is used. |
|
Type
of solver
|
Direct
or iterative solution type
may be selected.
|
|
Number
of sections on average member
|
Defines the number of section for evaluation
of results on a 1D member of "average length".
Section is always created in both end points
and under concentrated loads. The average length is determined
from the real length. Shorter 1D members contain fewer sections
while longer 1D members contain more sections.

Warning when maximal translation is greater than
|
If the maximal value of translation specified
here is exceeded, the user is asked to confirm that s/he still
want to review the results. This parameter is linear and nonlinear analysis .
|
|
Warning when maximal rotation is greater than
|
If the maximal value of rotation specified
here is exceeded, the user is asked to confirm that s/he still
want to review the results.
This parameter is linear and nonlinear analysis .

Note:
The adjustment of these parameters may affect the layout of the calculation
dialogue that opens on the screen when a calculation is started.
Note: For Mindlin bending theory of shell is used a mixed interpolation of transverse displacements, section rotations and transverse shear strains. It is an extension of a pure displacement formulation. For curvatures there is used an interpolation as the pure displacement on based elements but for shear strain are used another one. The mixed elements are not locked and do not contain any spurious zero energy mode.
