ProLB is based on the lattice Boltzmann method. Highly scalable, inherently transient, this method revolutionizes Computational Fluid Dynamics by reducing computational time while at the same time increasing accuracy.
The software suite includes LBPre for pre-processing. Results are exported in ParaView or Ensight Gold formats for Post-Processing.
ProLB users are provided with the source code for all the numerical models implemented. Expert users can implement their application-specific models or modify the existing ones: the wall-law, subgrid-scale model as well as the complete lattice Boltzmann numerical scheme
The software suite includes LBSolver for generating the volume mesh and processing.
LB-Solver features advanced, state-of-the-art turbulence-modeling techniques: DNS and LES. Large-Eddy Simulations are either based on the Shear-Improved Smagorinsky Model or on the Approximate Deconvolution Model. A pressure gradient-sensitive wall-law may also be employed. It integrates a correction for the viscous sub-layer as well.
Boundary conditions in ProLB are handled through an innovative Immersed Boundary Model. Thanks to this model, pre-processing is facilitated and most issues related to body-fitted meshes and element quality are eliminated.
The time required to generate the volume mesh is substantially reduced thanks to a parallel octree mesher. The volume is then discretized following the userdefined grid refinement regions.
Every step of the simulation workflow in ProLB can be automated to maximize productivity. Beyond scripting of the pre-processing, templates can be created for recurrent simulations. Post-processing in ParaView is automated via scripts provided using the ProLB software suite. Engineers can now focus on solving product-related issues rather on numerical one.
