Solving Nonlinear Coupled Problems Using Agros2D
Kůs, Pavel ; Karban, P. ; Mach, F. ; Doležel, Ivo
The paper describes the environment of the Agros2D code and presents several nonlinear coupled problems solved numeri-cally in this environment.
Actuator with Ferromagnetic Plunger Working in Ferrofluidic Liquid
Ulrych, B. ; Doležel, Ivo ; Polcar, P.
An electromagnetic actuator with a plunger moving in a ferrofluidic liquid is suggested and modeled. The paper analyses its principal operation characteristics.
Active thermal insulation for induction heating of specific metal parts
Ulrych, B. ; Kotlan, V. ; Doležel, Ivo
The concept of active thermal insulation is explained and its application for induction heating of specific metal parts is analyzed. Its features ale illustrated by a typical example whose results are discussed.
Adaptivity techniques in hp-finite element method
Karban, P. ; Doležel, Ivo ; Šolín, Pavel
Sophisticated methods of automatic adaptivity in finite element methods of higher order of accuracy are presented. The main attention is devoted to hp-adaptivity techniques that exhibit the highest level of flexibility and exponential convergence of results.
Hard-coupled model of local direct resistance heating of thin sheets
Karban, P. ; Mach, F. ; Doležel, Ivo
A monolithic model of local direct resistance heating of thin sheets is presented. The model respects all nonlinearities of the system such as the temperature dependencies of physical properties of individual parts of the system. Numerical computations are performed by a finite element method of higher order of accuracy and realized by our own codes Hermes2D and Agros2D. The methodology is illustrated by a typical example whose results are discussed.
