CD-adapco has announced that STAR-CCM+ v9.04, the latest release of its simulation software, includes new physics models useful for development and analysis of various types of OINDPs in addition to offering significantly faster operation.
The new version includes parallel meshing, workflow improvements, and optimization capabilities that will allow for “dramatic gains in productivity,” the company said, noting that simulations useful for understanding drug deposition behavior or for optimizing the design of an inhaler can be performed much faster using the new concurrent per part meshing functionality.
Some of the new models allow for simulation of suspension formulation interaction with valves or for condensation of aerosol droplets. Among the new features of this release are a Lagrangian droplets impingement heat transfer model and a coarse grain particle model based on discrete element modeling that allows for simulation of large numbers of particles in fluidized beds.
According to CD-adapco, “STAR-CCM+ v9.04 also lowers the entry hurdle for performing complex CFD simulations, allowing engineers to perform the simulations themselves without having to recruit the help of external consultants.”
