Hello, I wonder if someone could offer some insight on this issue. I am doing a very simple 1D transient thermal conduction/convection analysis. I am trying to define a time dependent boundary condition by defi
Time-dependent heat flux as boundary conditionPosted 2010年6月11日 GMT+8 07:05 Heat Transfer & Phase Change, Heat Transfer Version 4.1 1 Reply Virginia Ruiz Send Private Message Flag post as spam Hello: I am running a case where my boundary condition is heat flux, and it varies over...
Modeling of saturated and unsaturated soil with time dependent boundary conditionLogin
and i tried it having two PDE knodes and then select which one to use in the solution step subnodes, but then comsol gives an error message referring to the time variable t which appears in the boundary condition for the time-dependent case of course, but is not...
1b). The time-dependent drive is simulated by periodic modulation along a spatial axis in a static 3D lattice, which is a common method of realising Floquet dynamics14,30. Unlike static HOTIs, the corner states in the Floquet HOTI can oscillate in time, with oscillation period either equal...
Boundary condition: 4.2. Numerical solution Up to now, many simulation tools have been developed for flow in porous media such as TOUGH2, COMSOL, FEMLAB, COMET3 (Pekot and Reeves, 2002, Carneiro, 2009, Perera et al., 2011, Ye et al., 2014). Here a new numerical simulator was developed...
A fully coupled time dependent fluid-structure interaction finite element model (FEM) of the hydrodynamic stretcher (HS) was created using COMSOL Multiphysics (Comsol Inc.). The model uses an arbitrary Langrangian-Eulerian (ALE) formulation with a deformed mesh to capture the two-way interaction ...
gravitational body force was set to be ρ(T)g in the fluid domain. Temperature-dependent density data of Argon was taken from the COMSOL library. “Heat source” boundary conditions were applied on the volume of the nanohole array using the heat generation data exported from the electromagnetic...
The boundary condition, 𝑛·𝐷▽𝑐=0n·D▿c=0 was imposed at the outlet and the solid boundaries of the filter holder. The commercial CFD software program COMSOL Multiphysics 5.4 (COMSOL, Inc., Burlington, MA, USA), based on the finite element method (FEM), was used in this ...
The time-dependent charge carrier transport and recombination processes in low-mobility organic semiconductor diodes are obtained through numerical simulations using the finite element method (FEM). The application of a Lorentz force across the diode alters the charge transport process leading to the Hall...
