Spatial Methods | Kratos Multiphysics Documentation

Edit me

All the spatial statistical methods can be found in the SpatialMethods submodule. ValueMethods container will contain all available spatial value methods, and NormMethods container will contain all available norm methods.

Following example illustrates all the available value methods executed on nodal non historical variable velocity.

import KratosMultiphysics as Kratos
import KratosMultiphysics.StatisticsApplication as KratosStats
model = Kratos.Model()
model_part = model.CreateModelPart("test_model_part")
sum_value = KratosStats.SpatialMethods.NonHistorical.Nodes.ValueMethods.Sum(model_part, Kratos.VELOCITY)
mean_value = KratosStats.SpatialMethods.NonHistorical.Nodes.ValueMethods.Mean(model_part, Kratos.VELOCITY)
rms_value = KratosStats.SpatialMethods.NonHistorical.Nodes.ValueMethods.RootMeanSquare(model_part, Kratos.VELOCITY)
mean_value, variance_value = KratosStats.SpatialMethods.NonHistorical.Nodes.ValueMethods.Variance(model_part, Kratos.VELOCITY)

Following example illustrates all the available norm methods executed on nodal non historical variable velocity’s magnitude.

import KratosMultiphysics as Kratos
import KratosMultiphysics.StatisticsApplication as KratosStats
model = Kratos.Model()
model_part = model.CreateModelPart("test_model_part")
sum_norm = KratosStats.SpatialMethods.NonHistorical.Nodes.NormMethods.Sum(model_part, Kratos.VELOCITY, "magnitude")
mean_norm = KratosStats.SpatialMethods.NonHistorical.Nodes.NormMethods.Mean(model_part, Kratos.VELOCITY, "magnitude")
rms_norm = KratosStats.SpatialMethods.NonHistorical.Nodes.NormMethods.RootMeanSquare(model_part, Kratos.VELOCITY, "magnitude")
mean_norm, variance_norm = KratosStats.SpatialMethods.NonHistorical.Nodes.NormMethods.Variance(model_part, Kratos.VELOCITY, "magnitude")
min_norm, min_norm_id = KratosStats.SpatialMethods.NonHistorical.Nodes.NormMethods.Min(model_part, Kratos.VELOCITY, "magnitude")
max_norm, max_norm_id = KratosStats.SpatialMethods.NonHistorical.Nodes.NormMethods.Max(model_part, Kratos.VELOCITY, "magnitude")
min_norm, max_norm, group_upper_norms, group_histogram, group_percentage_distribution = KratosStats.SpatialMethods.NonHistorical.Nodes.NormMethods.Distribution(model_part, Kratos.VELOCITY, "magnitude")
