COMSOL 4.3b API Changes

Physics Interfaces

•

The Crosswind diffusion formulation has been updated for all physics interfaces supporting Crosswind diffusion. Models solved with the new formulation can give different results than models solved in versions earlier than 4.3b. Java® files can be modified to retain old crosswind formulations. Please contact COMSOL Support for details.

•	The default settings have changed for the Background Pressure Field in the Pressure Acoustics interfaces. Add the following line to obtain the old behavior of this feature:

model.physics("acpr").feature("bpf1").set("c", 1, "acpr.c_c");

•	In the Acoustics Module, the Far-Field Calculation feature is no longer available in 1D and 1D axisymmetric models.

•	The shape function property border has been deprecated and replaced by order.
