GeneralStep

class compas_fea2.problem.GeneralStep[source]

Bases: Step

General Step object for use as a base class in a general static, dynamic or multiphysics 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.

restartfloat, optional

Frequency at which saving the results for restarting the analysis, by default False.

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.

restartfloat

Frequency at which saving the results for restarting the analysis.

loadsdict

Dictionary of the loads assigned to each part in the model in the step.

fieldsdict

Dictionary of the prescribed fields assigned to each part in the model in the step.
