PLM on the Cloud

HPC-Competence Center

Arctur prides itself in not being just another HPC infrastructure provider, but rather one which always provides personal support even to users which are not so knowledgeable of HPC, so ensuring that every HPC project achieves or even surpasses user expectations. Their motto is “More than just HPC.” As an SME, they understand the issues that other SMEs face when dealing with HPC.

The Enterprise

Stellba is a Germany-based SME working on hydropower plant maintenance, repair and overhaul, engineering and manufacturing one-of-a-kind products for the green energy sector with the goal to optimize energy efficiency.

How HPC makes the difference


The simulation process results in huge amounts of files and data with many different representations of the 3D product model.

This success story is an outcome of CloudFlow project(*).
Engineering analysis processes include activities such as product design and product analysis, including mesh generation, definition of boundary conditions, simulation, and post-processing. In any engineering company the highly iterative simulation process results in huge amounts of files and data with many different representations of the 3D product model. For an engineer it is a challenge to keep an overview of related data (configuration control) and extract the essential information for product optimization, demanding a user-friendly overview over configuration controlled data sets and an easy and fast visual inspection.
For the process of managing evaluation results, the end user Stellba uses a multitude of different software packages with high license costs, training efforts and requirements towards human skills. The process is tedious and the locally installed software packages limit accessibility to the corresponding computers – there is no remote / web access. So, on average, Stellba spends four weeks on organizing and reviewing simulation results in parallel to running the simulations themselves.
With the help of HPC the time for reviewing and managing simulation results at Stellba is being reduced by saving about 40 person-hours of work for a medium-sized turbine optimisation project. By shortening the elapsed time for handling projects, Stellba’s capacity for new projects increases and reduced product costs lead to better competitiveness.
