"""
This function creates the A4 analysis, complete existing model NLTH with linear material properties and without
connections and soil-structure interaction. It depends on the software set, which will switch between explicit
(ABAQUS) and implicit (DIANA) analysis.
Input:
- project (obj): VIIA project object containing collections of fem objects and project variables.
- iteration_method_requested (str): The iteration method selected for the time-steps execute, the default value
is 'secant'. Other options are 'newton-raphson', 'linear-stiffness' and 'constant stiffness'.
- output_1c (bool): Select to create output-block 1C for additional signal checking. Default value is False.
- nr_time_steps (int): Overrule the number of time-steps to be used in the NLTH analysis. Default value None,
time-steps are determined based on the length of the signal.
Output:
- Creates and returns the A4 analysis object for the requested software with all settings for VIIA.
