PFEM Integrator

The PFEM integrator is a specialized integration method for fluid-structure interaction analysis using the Particle Finite Element Method.

Description

This integrator is particularly suitable for:

• Fluid-structure interaction problems

• Free-surface flows

• Large deformation problems

• Multi-physics simulations

• Problems involving fluid sloshing and splashing

The PFEM integrator is specifically designed to handle the coupled physics in fluid-structure interaction problems using the Particle Finite Element Method.

Parameters

The PFEM integrator accepts the following parameters:

Parameter	Description	Default	Notes
gamma	Gamma factor	0.5	Optional
beta	Beta factor	0.25	Optional

Usage Example

# Create a PFEM integrator with default parameters
integrator = fm.analysis.integrators.create_integrator("pfem")

# Create a PFEM integrator with custom parameters
integrator = fm.analysis.integrators.create_integrator("pfem",
                                                gamma=0.6,
                                                beta=0.3)
