Yes you can. Check the example below. It changes the relative permittivity with the level set function but you could use the same functionality to apply a charge: https://www.comsol.com/model/taylor-cone-with-level-set-3828 dongjie fu ...
In the case of no overhead, the result is as predicted by Amdahl’s law(last picture), but when we start adding overhead, we see that something is happening. Speedup with added overhead. The constant, c, is chosen to be 0.005. Different line represents the different function that descri...
This example studies in detail how to create uniform droplets in a microchannel T-junction. Setting up the model you can make use of the Laminar Two-Phase Flow, Level Set interface. The model uses the predefined wetted wall boundary condition at the solid walls, with a contact angle of 135...
The memory requirements for a model with two spatial dimensions do get larger, but still not exorbitantly so. An example of such a case of optimizing a 2D model with the third dimension being time is also presented via the link below and includes theElectric Currentsphysics in addition to he...
one reason for this error could be that some boundary conditions (for example, for laminar inflow in fluid-flow models) add dependent variables that are not initially in the model.7 36、043initial guess leads to undefined function valuethis error message usually appears when you have set up ...
For example, the current’s unit is A*m in the new version while in the old one it was A. plus, the calculated value in the new model is totally different that I couldn’t figure out why. My model is as follows: I modeled a single turn using 2D-axisymmetric modeling in ACDC (...
