Parametric Sweep messes up Geometry. The results will be available within a single Data Set that contains all the parametric solutions. The overhead comes from the fact that for each parameter, a separate COMSOL Multiphysics process is started. Add depth as the continuation parameter, and click the range button. For the parametric sweep, I'm trying to do a logarithmic sweep from negative numbers to positive numbers. Completely Parallel — A completely parallel problem arises when you use the Parametric Sweep functionality, such as when sweeping over a range of geometric dimensions. Geometries are defined by sequences of operations, where each operation is able to receive input parameters for easy edits and parametric studies in multiphysics models. Your external Parametric Sweep node tells COMSOL to loop all around the model, (I believe not rereading Parameters, but all the rest Yes) in this way your parameter sweep can update the geometry, get the mesher to remesh, and then Solve the model.

Lina. Meshing issues. What a generally do is: (1) calculate the study with the parametric sweep (2) Create a new table wich contains the results (2) Generate a plot from the table The positive aspect of a sweep analysis is that it indicates the optimal values’ space, which helps to minimize the search domain and speed up the computational time when using more robust procedures. The Parametric Sweep study step is used to sweep the angular speed, a Time Dependent study step is used to perform a time-dependent analysis corresponding to each angular speed in the parametric sweep, and a Time to Frequency FFT study step takes the fast Fourier transform of the time-dependent data to convert into the frequency spectrum. The Batch Sweep — in contrast to the Parametric Sweep — is using multiple COMSOL batch instances to process the parameter cases. The instances are launched as external batch jobs from a Batch Sweep study run in the GUI. Scholarly publications with full text pdf download.
