KARALIT provides a CFD software that is based on the IB technique.

This technique was hampered, however, by the lack of an effective numerical theory for generating the cells that intersect with the object’s surface and was discarded in favor of mesh generation techniques.Īs geometries became more complex and the size of the data started to increase exponentially, so did the time it took to generate the meshes, and interest in Immersed Boundary methodologies was renewed.Īmong the first to commercially and successfully harness the power of this time-saving methodology is KARALIT, a start-up company headquartered in Pula, Italy.

It also did not require morphing, which can deteriorate the mesh, or re-meshing the computational domain when the geometry is changed. The promise of IB was that it could eliminate the time spent on the set-up and generation of a mesh. Instead of running Navier-Stokes equations on grids that conform to the shape of an object, as is done with meshing, the IB technique immerses a CAD model of the object into a Cartesian grid and then integrates the equations into that Cartesian grid. The Immersed Boundary (IB) methodology, a mesh-free technique for running CFD simulations, has been around since the 1970s. « Back CFD Simulation Analysis Times Reduced Aerodynamics, Automotive, Case Studies, Chorus January 13, 2015Ĭase Study: Tecplot Chorus integrates with KARALIT CFD to save time with mesh-free CFD simulations and analyses
