Parameters

in_model
Type: Karamba.ModelsModel
model for which cross sections shall be optimized.
n_samples
Type: SystemInt32
number of points along the beam axis for which the cross section design is to be checked. The minimum is two for beams. For shells the minimum is one. Larger values than one for shells have currently no impact.
elast_design
Type: SystemBoolean
true if cross section design should be elastic, otherwise plastic design is performed.
uls_iter
Type: SystemInt32
number of iterations for the ultimate limit state.
sls_iter
Type: SystemInt32
number of iterations for the serviceability limit state (limiting maximum deformation).
max_deform
Type: SystemDouble
maximum deformation not to be surpassed by optimized structure under any load-cases.
max_deform_dir
Type: SystemNullableVector3
direction in which the deformation shall be measured. If zero the absolute value of the displacements is used.
target_util
Type: SystemDouble
target value for the element utilization.
elem_ids
Type: System.Collections.GenericListString
identifiers of elements to be optimized. If empty all elements are optimized.
elem_grp_ids
Type: System.Collections.GenericListString
identifiers of element sets which shall have identical cross sections. In case of shells all faces of the shell have the same height.
in_crosec
Type: System.Collections.GenericIReadOnlyListCroSec
sorted list of cross sections to select from for optimization. Cross sections coming first are first tested for appropriateness.
bisection_search
Type: SystemBoolean
if true then sufficient cross sections are searched for using a bisection algorithm.
gamma_m0
Type: SystemDouble
Safety factor on the material if buckling does not govern the cross section design.
gamma_m1
Type: SystemDouble
Safety factor on the material if buckling govers the cross section design.
swayFrame
Type: SystemBoolean
Flag indicating buckling involving sideways sway of the structure.
max_displacements
Type: System.Collections.GenericListDouble
maximum displacement in each load-case after optimization.
compliances
Type: System.Collections.GenericListDouble
resulting compliance (i.e. internal elastic energy) for each load-case.
message
Type: SystemString
information regarding the optimization run.
model
Type: Karamba.ModelsModel
model with optimized cross sections.
