This paper presents a compact electro-mechanical-fluidic system-modeling method for multidomain system simulation based on multidomain physics that considers the total energy conservation condition, in terms of respective potential and flow quantities. Models for electrical, mechanical, and fluidic domains are developed to design the example of a blood pumping system, where the blood flow is driven...
Numerical thermalization induced by discrete-particle effects was observed in particle-in-cell (PIC) simulations1, which show that the thermal relaxation time scales with ND2 and ND for one-dimensional (1D) and two-dimensional (2D) models2, respectively. The parameter ND denotes the number of particles in a Debye length (1D) or a Debye square (2D). However, it was found recently that the thermal relaxation...
A new modeling framework of an electrically driven fluid flow system for mixed-domain circuit simulation is reported. Coupling between electrical and fluidic domains is implemented by developing an organic actuator compact model. The actuator model is based on force balance spring-mass-damper system equation. Fluid compact model is derived from mass transport equation. The actuator and the fluid models...
In this paper, the impact of the skin modeling and displacement currents on the induced electric field evaluated by low frequency solvers has been investigated. Both a simplified canonical test-case and a realistic hand-touching electrical stimulation have been selected as meaningful applications without any loss of generality. Similar considerations are indeed expected for other induced contact current...
This paper investigates the electric field and current density induced in a human body when exposed to low frequency electromagnetic fields. A numerical technique based on the Finite Element Method and electromagnetic quasistatic approximations is employed to compute both the fields generated by low frequency sources and the fields induced inside a human body due to exposure or contact. Case study...
This paper investigates the electric field and current density induced in a human body when exposed to low frequency electromagnetic fields. A numerical technique based on the Finite Element Method and electromagnetic quasistatic approximations is developed to compute both the fields generated by low frequency sources and the fields induced inside a human body due to direct or indirect exposure scenarios...
A Taylor-type crystalline plasticity model, implemented into the commercial finite element analysis software, is coded as a subroutine to investigate the behavior of a stainless steel sheet with a body centered cubic (BCC) structure in the current study. Thickness variations of the sheet are examined under the micro-groove formation procedures. Effects of the spatial distribution of crystallographic...

In the context of the SMOS mission, a new numerical method based on the finite element method is presented which can be used to model the radiometric L-band emission of soil and litter layers in forests. Many different characteristics of these layers that affect the soil-litter emission can be incorporated into the model, including surface roughness, inclusions and volume effects. Soil moisture is...
