Fast and Scalable Input/Output
Format independent solution
Input
Parallel loading of unstructured mesh databases
Our I/O module is designed to efficiently load sequential mesh database files and perform high-quality domain decomposition. It has been developed from the ground up as a highly parallel tool designed for HPC environments including the high-performance storage systems. It is composed of several commonly used approaches that together provide to a robust solution.
- Supported formats
- OpenFOAM
- NetGen
- EnSight
- VTK
- ANSYS_CDB
- Abaqus
- New format support can be developed based on customer requests.

Workflow
PreProcessing
Create unstructured meshes in your favorite robust and efficient preProcessing tool as you are used to doing, and export database files from the preProcessing tool in your preferred format.
ESPRESO Scalable I/O
Fast parallel processing and hybrid domain decomposition of unstructured meshes with direct connection to the massively parallel solvers.
Standard Solution
In common open-source approaches, the sequential converting to a parallel native format is needed. This creates sequential barriers for scalable solvers.
Supercomputer
Solve the problems at the top of your database files
Asynchronous Output
For the PostProcessing purpose, storing result outputs to commonly used PostProcessing formats are implemented.
Output to commonly used postProcessing formats EnSight and VTK
Overlapping ongoing computation by storing solution results
Result monitoring of selected regions for statistical and optimization toolchains
Solution restarting without ties to the previous number of resources
