What Can Ennova Do

Once one has made the leap to multiple cores, it is not much harder to take advantage of clusters of multi-processor computers. But to do this with an application with heavy 3D modeling requirements requires splitting the application into a client part that runs on the desktop using the high performance graphics of a workstation and a server part that runs on the parallel compute resource. With Ennova, the only big data that resides on the desktop is the display list that you see.

Ennova uses a proprietary parallel architecture that utilizes modern multi-core CPU's to speed up CAD import, CAD cleanup and mesh generation by factors of 10x or 100x

Ennova leverages the Hoops Exchange technology from Techsoft3D. Click here for more details.

CAD data for CFD is usually generated as part of the manufacturing design process and often is not of the quality needed for CFD. Click here for more info.

Ennova is a scalable product, designed for the large, complex datasets prevalent in CFD. It is a client/server application with a distributed architecture on the server side, which can be deployed on either a public or private server. Ennova does not try to load the model onto one master node with large memory requirements, but distributes the model over many nodes with a modest memory requirement on each node. In addition, the client runs locally taking advantage of the local graphics hardware acceleration and requires modest bandwidth. Therefore, the size of the model is not limited to the amount of memory on the local machine.

Ennova is built on our own proprietary geometry kernel. This kernel enables scaling of geometry cleanup and mesh generation by as many cores as you have available. Click here to find out more.

Mesh Topology is a unique Ennova technology. It is a software layer that lies between the raw CAD data and the geometry cleanup and meshing algorithms. This layer servers multiple purposes. It allows Ennova to treat the original CAD geometry as read-only even while it repairs it. It allows the meshing algorithms to construct geometric objects like swept regions and structured regions that do not correspond to any CAD entity.

Ennova is a complete meshing tool. Depending on the type of analysis and solver used often different types of grids need to generated. These different types of grids can be for surface meshing or volume meshing. As well as solver often geometry plays a role in determining the type of mesh generated.

Our developers, as the original creators of ICEMCFD, have many years of experience in crafting grids for external or aerodynamic flows. It is well known that for high quality aerodynamic solutions, structured grids or multi-block structured grids preform well in most solvers. However, structured or multi-block structured grids are not easy or fast to make on anything but the simplest conceptual geometry, and they often require hours of manual input to make a grid.
