Since the CWE interface is suited for solving large acoustic problems (measured in the number of wavelengths per geometry unit it can handle), the model solved can easily contain many million degrees of freedom (DOFs). Storing the solution with a desired time resolution can thus results in huge data files. To circumvent this, a good practice is to use the Store in Output option found in the main Time Dependent solver (for example, in the Study 1 > Step 1: Time Dependent node). Using the Selection option in Output, it is possible to only store data on predefined selections. This can, for example, be on a symmetry plane, along an edge, or at the location of a receiver in a model. When postprocessing the data, best results are obtained by adding the same selections to the dataset used.
