COMSOL 6.4 - The Microfluidics Module Study Capabilities by Physics Interface

Table 1-2 lists the Preset Studies available for each physics interface specific to this module.


	When using the axisymmetric interfaces, the horizontal axis represents the r direction and the vertical axis the z direction. The geometry must be created in the right half plane (that is, only for positive r).
