model_part_name is the model part which all of the mentioned statistics will be calculated. input_variable_settings contains list of statistical methods, their norms and container combinations where statistics will be calculated. under each input_variable_settings_block, method_name is the statistics method, norm_type is the norm type ("none" for value methods, other wise norms are used), container to tell from which container to read/write, method_settings to specifiy input/output variables for the method. Apart from that, there are few global settings. statistics_start_point_control_variable_name is the temporal statistics calculation start control variable name. This variable should be present in the model_part specified in order to calculate temporal statistics. Statistics calculation will start when this variable’s value passes user specified value in statistics_start_point_control_value.
