Making The Case For Using A Cloud Hosted CFD Solver

Home » Blog » Making The Case For Using A Cloud Hosted CFD Solver

EXN/Aero is a whole new kind of CFD solver. In this article, we lay out some of the key arguments sure to convince any engineer to embrace our on-demand, cloud-hosted CFD solver, ultimately saving time and money. 

Why Use A Cloud Hosted CFD Solver?

While most engineers want more affordable access to CFD simulation power, cloud-hosted CFD solvers remain relatively new and as such, some perception barriers exist around their adoption. Cloud hosted CFD solvers have the potential to help improve cash flow, improve a businesses ability to compete when pitching for new business, and actually improve collaboration and security.

Reasons To Embrace Cloud Hosted CFD

Here, we've pulled together a number of solid arguments in favour of adopting a cloud-hosted CFD solver.

You're probably not totally satisfied by your current CFD solver and could be being held back.

Well, from our recent CFD survey we know just 14% of respondents are satisfied with their current simulation setup. In many cases, engineers are 'working with what they have', potentially limiting their capability, extending project times, and even reducing their overall competitiveness.

Being 'reactive' is no longer a viable option. You need to be 'proactive' with CFD software such as EXN/Aero.

The traditional way of reacting to increasing simulation needs has been to invest in expensive hardware, even to sacrificing accuracy for speed. Here at Envenio, we've always believed there's a better way of doing things, and instead adopted a proactive approach to embrace the many emerging HPC trends. By utilizing the cloud, our CFD solver is made for the future, allowing engineers access to more affordable simulation power when they need it.

EXN/Aero has already embraced the HPC revolution.

EXN/Aero was designed from scratch to accommodate the evolution of high-performance computing CFD toward heterogeneous computing architectures, which involves diversity in both memory organization and the type of computing core. Therefore EXN/Aero can solve HPC CFD problems using traditional multicore CPUs, or manycore GPUs or a combination of CPU’s and GPUs. Load balancing of the CFD solution over manycore CPU/GPU resources applies to all computational tasks in the solution.  

EXN/Aero embraces the many-core factor.

Anticipating the increased computing power with many-core computing, along with increasing latency costs with data transfers, additional parallelization is built into our CFD solver EXN/Aero by employing domain decomposition both in space and in time.  Domain decomposition in time is characterized by low overhead in communication cost and can be used to maximize the use of available computing core on devices such as GPUs. A recent article explored HPC's time of change and the many-core era, considering what this change could mean for the world of simulation. Intel also presented a paper on the future of manycore computing for the wider I.T world.

You can use structured, unstructured or hybrid meshing.

To maximize computing performance EXN/Aero allows problems to be setup isolating structured mesh regions, that can be more efficiently transferred, stored and executed on manycore hardware such as GPUs, from regions using unstructured meshes. Problems can be run entirely structured or entirely unstructured, or a combination of both data types.

The ability to identify single or double precision areas further improves computing performance.

To further improve computing performance, EXN/Aero, on top of subdividing problems into structured and unstructured regions, allows regions to be identified as single or double precision. Double precision requires double the memory and data transfer overhead than single precision, along with decreased floating point performance. Limiting double precision numerics only to regions where needed improves computing performance.

The cell and interface design creates a natural organization of data and provides a high-level of flexibility for incorporating multi-physics models.

Our CFD solver employs a high-level object oriented design breaking problems up into a collections of cell and interface objects (interfaces connect cell objects and also connect to the outside world), with each object type have a set of attributes which can among many things include destination computing resources (based on CBMM load balancing) and data type (structured/unstructured) and precision (single/double).  Executions of tasks on the cell and interface objects data involves straightforward low-level programming, supporting efficient computing and ease in code development. 

You'll enjoy ultimate flexibility, and you won't be restricted with expensive annual licenses.

Unlike many traditional CFD options, Envenio's cloud CFD solver comes without the expensive annual licenses, allowing engineers to access high performance CFD on-demand. Essentially this flexibility enables engineers to punch above their weight when it comes to simulation power, for an affordable monthly fee without the tie-in. Additionally, engineers can choose to use EXN/Aero only when a client or project demands.
