But what if the fluid is incompressible? Bryce received a B.S. To start a new discussion with a link back to this one, click here. Then you should point the integration domain of interest. If, on the other hand, you want to make the results of a time integration available within a model, add a Domain, Boundary, Edge, or Point, or the Global ODEs and DAEs interface. Hi, I am a COMSOL-beginner with what I guess might be a quite basic question. As your partner in disruption, we help you design, develop and . For example, suppose that you have defined the normalized Gaussian function via a Global Variable: G = exp(-((t-0.5[s])/(0.1[s]*sqrt(2)))^2)/(0.1[s]*sqrt(2*pi)). Kim holds a Masters in Management: Information Systems and Services from University of Maryland, a B.A. Thanks a lot! Followed is the thread link I posted with the model file attached, only if you could take a look. You can also use the timeint operator in any results evaluation. That is, the variable Pressure takes on whatever value is needed so that the enclosed area of the deformed shape equals the initial area. I checked the solver, it is using fully coupled direct solver by default. We will introduce one more equation into this model, via the Global Equations feature added to the Solid Mechanics interface, to solve for the pressure within the fluid such that the volume doesnt change. Volume Integration and Surface Integration. The information provided may be out of date. This equation is solved from the initial value TimeInt=0 and thus it computes the integral, from t=0 to the current time, of the expression G. Note that you can take a time integral of the results of a spatial integral, meaning that the expression G could be replaced with an integration operator, for example. listed if standards is not an option). Making Structures Stronger by Removing Material. In 2D the volume is the surface integration * depth (often called "d", sometimes simply normalised to 1 [m] all physcs . The example computes the compressive force, and compares the result of including the effect of the compressible air within the seal with the result of not including it. Were the the mission-driven link between data and action. Now you must choose the correct reference frame (depends also on which physics) to get the volume before / after some changes. An easy way would just be to define a subdomain integration coupling variable, name it "volume," and use 1 as your expression. Ivar. Volume Integration of revolution 2D.
