Whatever meshing software you use, you need to add Bolt to your tool chest. Bolt is a push-button solution for generating all-hex meshes from complex geometries with little or no user interaction. Most models can be meshed by simply clicking the Mesh button. For other models, use the mesh controls to adjust mesh, size, and smoothing.

Get excellent results—fast.
For many complex simulations, Bolt produces equivalent or superior results when compared to pave-and-sweep meshes that take hours or days to generate. Depending on the type of analysis you are doing, Bolt can give you excellent results in minutes.

No more cutting up models.
Traditional pave-and-sweep meshing methods require you to decompose the model into sweepable volumes. This could be more than 60% of the time it takes to get a good mesh. Bolt uses a very advanced overlay-grid method to generate an all-hex mesh. Unlike the pave-and-sweep method that takes hours or days to prepare, Bolt allows you to mesh your model with the simple click of the Mesh button.

Tolerant of dirty geometry.
You know that all geometry is not the same. Many of the models you get from a designer require significant clean up and defeaturing. Repairing problems takes time, a lot of time. Bolt doesn't require you to manually fix gaps, overlaps, or misalignments. Bolt uses a new volume fraction approach that has been developed and tested for more than six years to accurately represent the topology of your model without having to fix it first.

Massively parallel.
Even without having to clean up and prepare your geometry, large and complex models can take a long time to mesh. Bolt speeds up actual meshing time by dividing the model into parts and meshing each part in parallel. Bolt's meshing algorithm is massively parallel and will use as many processors as specified and available.
