Nika has developed a number of Key Technologies to allow their users to concentrate on their problems and not be distracted by the inner workings of the program yet still maintain the highest level of mathematical rigidity and physical significance. These technologies include:


This technology enables the user to perform the fluid flow analysis directly on the native solid body of the model. The user defines inlet and outlet boundaries, by means of lids for internal flow (e.g. flow through pipes), and the program automatically detects the fluid region.


This allows the mesh to automatically adapt to the geometrical and/or physical requirements of the model. Additionally, the user has the ability to change these parameters manually if so desired.


One of EFD's strengths, and one that enables solutions to be found quickly, is the technique of applying empirical data to the region of partial cells, these being cells that are bound on once side by solid and the other by fluid, to approximate the boundary layer remarkably reliably.


With this technology, there is no need to specify the flow characteristics of the fluid in an application. The flow regimes are dealt with in the same flow model.


Nika claims very robust convergence behavior of the solver to a solution.


Nika refers to this as a "what-if" analysis.


The GUI is easy to learn, presented for the engineer and is similar in feel to the MS Office Suite.
