is the dependent variable. By the definition of the divergence of the gradient of a scalar variable, I assume what I should do is define avariablein COMSOL like below Laplacian_xi=d(d(xi,x),x)+d(d(xi,y),y) which corresponds to . However, if I p...
How to define a value that is evaluated through iteration in COMSOL 4.0Login
This is true according to common sense. But in the numerical model it's different. I define a homogenous initial temperature for a domain. When I choose a different boundary temperature, then this changes the COMSOL model initial temperatur field even at the time t=0. I.e. it ove...
Our laser heating model already defines aGlobal Parametercalledemissivity, which is a constant value of 0.8 and is used within the model to define both the absorbed and radiated heat. We can remove this constant global definition and instead define a state variable over the top surface, of the...
A detailed description of both of these coefficients and how to define them is given in theUser’s Guidefor the Acoustics Module, under the section on theThermoviscous Acoustics, Frequency Domaininterface in theThermoviscous Acoustics Modelsection. TheVibrating Particle in Water — Correct Thermovis...
(rp-var-define 'my_monitor 0.0 'real #f)That defines a variable called my_monitor, and it has a real type and an initial value of 0.2. Write the report value into the variable defined in step 1. For example, if we want to write the mass flow rate into my_monito...
Now that we have the curve objects that define the outline of each cross section of the head, we can create the solid shape with theLoftoperation. TheLoftoperation is one of the geometry modeling tools included inthe Design Module. Before setting up theLoftoperation, we need to make sure th...

(4,solid.sx)rather thansolid.sx, you will plot a stress that is smooth over the element. In this case, the nonlinear stress–strain relation is evaluated only at the Gauss points where it is already fulfilled. Then, a least-squares fit of the Gauss point values is used to define a ...
We can also use theInelastic residual strainsocket to define a description of an inelastic strain contribution to the overall material model. An example of this would be if we wanted to add our own creep strain term to the built-in linear elastic material. TheInelastic residual strainsocket ass...
