time_freq_interpolation#

Autogenerated DPF operator classes.

class ansys.dpf.core.operators.math.time_freq_interpolation.time_freq_interpolation(fields_container=None, time_freq_values=None, step=None, interpolation_type=None, force_new_time_freq_support=None, time_freq_support=None, config=None, server=None)#

Interpolates between all the matching fields of a fields container at given times or frequencies, using ramped: fieldOut = field1*(1.-fact)+field2*(fact), or stepped: fieldOut=field2. If the time freq is higher than the max available, the field at the max time freq is taken. Computes the output time freq support to support the fields container

Parameters:

  • fields_container (FieldsContainer) –

  • time_freq_values (float or Field) – List of frequencies or times needed. to specify load steps, put a field (and not a list) in input with a scoping located on “timefreq_steps”.

  • step (int, optional) – If a field is set as input, the step ids should be its scoping.

  • interpolation_type (int, optional) – 1 is ramped, 2 is stepped, default is 1.

  • force_new_time_freq_support (bool, optional) – If set to true, the output fields container will always have a new time freq support rescoped to the output time_freq_values (default is false). if set to false, the time freq support is only recreated when time or frequency values are between existing ones.

  • time_freq_support (TimeFreqSupport, optional) –

Returns:

fields_container

Return type:

FieldsContainer
