Heat transfer setting temperatures not affected by material

So when I do a heat transfer (stationary, 2d), I have a rectangle and I set the top and the sides to 300K, and the bottom to 600K. Then I do temperature profiles of these conditions for two materials...

No change in laminar flow simulation results even after changing material...

Hi, I have been doing very straight-forward and simple laminar flow simulations in a chamber. I have observed that flow simulation results don't change if I add and use another fluid with different...

Flow through a concentric annulus

Hi, I have some problems for the simulation of a simple flow trough a concentric annulus. I use an axisymmetric model in which only the annular duct is defined (the model is attached here). Then, for...

How to add a condition on the mode solver when using the parametric sweep?

Hi, I am using the RF module of COMSOL 4.3b to determine the effective refractive index of the modes of a waveguide as a function of the wavelength (for instance between 600 and 700 nm). I am therefore...

heat transfer in porous media and conjugate heat transfer

Hello everyone, I'm new to Comsol and I'm trying to couple the heat transfer in porous media with the conjugate heat transfer (solid + water in laminar flow). But i have a lots of problems. I would...

AC impedance of a dipole

Hello, I am at the moment trying to simulate a simple system and I am having a few problems. I am trying to calculate the self impedance of a dipole located inside a full space of conductivity 0 and...

Plasma Module Error: Failed to Evaluate Variable Jacobian

I am attempting to model a DC microdischarge in Argon using COMSOL 4.2. I am using a 2D axisymmetric model. The top layer is the anode, the middle layer is a dielectric and the bottom layer is the...

Tracking position of isothermal or general contour curve in 1D plot

Hi everyone, I have very simple model where copper plate is heated by a pulsed laser (transient study, 2D, see file surfaceplot_1). Now, I am searching for a way to track the position/depth of my...

Large mesh with Beam Envelopes module

Dear all, probably I'm missing something about the use of the Electromagnetic Waves, Beam Envelopes; as I understand well, this module can be used to simulate a long waveguide (some mm or cm long) but...
