StaticStep

class compas_fea2.problem.StaticStep[source]

Bases: GeneralStep

StaticStep for use in a static analysis.

Parameters:

max_incrementsint: Max number of increments to perform during the case step. (Typically 100 but you might have to increase it in highly non-linear problems. This might increase the analysis time.).
initial_inc_sizefloat: Sets the the size of the increment for the first iteration. (By default is equal to the total time, meaning that the software decrease the size automatically.)
min_inc_sizefloat: Minimum increment size before stopping the analysis. (By default is 1e-5, but you can set a smaller size for highly non-linear problems. This might increase the analysis time.)
timefloat: Total time of the case step. Note that this not actual ‘time’, but rather a proportionality factor. (By default is 1, meaning that the analysis is complete when all the increments sum up to 1)
nlgeombool: if True nonlinear geometry effects are considered.
modifybool: if True the loads applied in a previous step are substituted by the ones defined in the present step, otherwise the loads are added.

Attributes:

namestr: Automatically generated id. You can change the name if you want a more human readable input file.
max_incrementsint: Max number of increments to perform during the case step. (Typically 100 but you might have to increase it in highly non-linear problems. This might increase the analysis time.).
initial_inc_sizefloat: Sets the the size of the increment for the first iteration. (By default is equal to the total time, meaning that the software decrease the size automatically.)
min_inc_sizefloat: Minimum increment size before stopping the analysis. (By default is 1e-5, but you can set a smaller size for highly non-linear problems. This might increase the analysis time.)
timefloat: Total time of the case step. Note that this not actual ‘time’, but rather a proportionality factor. (By default is 1, meaning that the analysis is complete when all the increments sum up to 1)
nlgeombool: if True nonlinear geometry effects are considered.
modifybool: if True the loads applied in a previous step are substituted by the ones defined in the present step, otherwise the loads are added.
loadsdict: Dictionary of the loads assigned to each part in the model in the step.
gravitycompas_fea2.problem.GravityLoad: Gravity load to assing to the whole model.
displacementsdict: Dictionary of the displacements assigned to each part in the model in the step.
