Comsol time dependent study tutorial

Doublestar complete upper

I would like to do a time dependent study (and particle tracing possibly) on a straight channel. After I do the stationary study, I do not have clear ideas on how to proceed. Would you mind giving me step-by-step instructions or sharing a template please? Thank you, Antonio

Acoustics Module Updates. For users of the Acoustics Module, COMSOL Multiphysics ® version 5.5 includes a new Elastic Waves, Time Explicit Physics interface, multiphysics couplings for acoustic-structure interaction with the time explicit formulation, and a Port boundary condition for the Thermoviscous Acoustics, Frequency Domain interface. COMSOL Multiphysics ® version 5.3 provides you with notable performance improvements as compared to earlier versions. You will experience speedup by a factor of up to ten in software responsiveness, as well as new and improved features for solving, meshing, and the physics-based add-on modules. There's something about the time dependent studies in COMSOL that I'm not able to understand and I would like you to help me if possible. I am solving a heat transfer problem and, to do this, I am using a time dependent study. I have done two different simulations: The heat exchanger in this tutorial model contains a dynamic wall with an oscillating wave shape. The deformation induces mixing in the fluid and reduces the formation of thermal boundary layers. For a time dependent problem it can be useful to do a stationary study step and then take the stationary solution as an initial value for the time dependent step. But you have to take care that the time dependent situation at t=0 approximates the stationary situation.

I am working with composite thermal barrier case using Heat Transfer Module of COMSOL software. Pls how can I draw/get the temperature profile of the time-dependent study of 3D and 2D plots in COMSOL. So, I am trying to see the simulation results for time dependent analysis (for example range 0 to 5ms, step size 1us). When I compute the time dependent study, it is working but the pressure or displacement in the Ti does not changing with respect time(for 1D plot). If you have time can you please look at my model.

Defining the Global Time Parameter. To study both steady-state and transient responses, it helps to define a global parameter t with the unit of time, and a time-dependent generation rate gR using the global parameter t and a global piecewise function pw1, which, in this model, describes a triangular pulse of peak value of unity.
