Admin Tool upgraded to 2019.4
In Admin Tool 2019.4, the following new features are introduced:
- On Windows, when the Random MAC address is enabled, the host ID of the machine could change, which could result in invalid license file. The License Management menu of the Admin Tool allows to detect it and inform the user: the machine details are not displayed.
- On Windows, when a non-ascii path is used for the installation directory, a warning is appearing before starting the Admin Tool with a recommendation to avoid non-ascii path.
- On Linux, FlexLM requires LSB (Linux Standard Base) compliance. The License Management menu of the Admin Tool detects if the lsb-core is installed and allows to install it as sudo if not installed.
- The license information (path of the used "License_management" directory, host name, host IDs) can be retrieved at the top of the License Management menu of the Admin Tool.
- FlexLM version is upgraded from 11.14 to 11.16
General upgrades in package
General upgrades are made in the package:
- End of support for Ubuntu 14.04 LTS, Fedora 22 and Fedora 25.
- Beginning of support for Ubuntu 18.04 LTS.
- Use of PGI 18 compiler. When launching a computation on Linux using the executable compiled with PGI 18, the argument -pgi should be used.
- Upgrade Intel MPI to 2018.0 on Windows.
- Removed directory _python_admin because the FINE™/Open chain does not use it anymore.
FINE/Open with OpenLabs
First order upwind initialization in the user interface
Starting from FINE/Open with OpenLabs 9.1, the first order upwind initialization is available in the interface. The compatibility scope of the functionality was extended to CPU-Booster applied on the finest grid level
Upwind schemes with Merkle preconditioning for all type of fluids
The 1st/2nd order upwind schemes are extended to be compatible with the Merkle precondtioning for all type of fluids. When the Merkle preconditioning is selected, the upwind scheme cannot be accessed in the GUI. Users have to activate the upwind scheme through the expert parameter upw_precond_=1.
Show information used to generate the current combustion table
When generating a combustion table in FINE/Open with OpenLabs 9.1, the information used to generate the table will be saved in the generated table. After selecting the combustion table for non-premixed or partially-premixed combustions in the GUI, clicking the button Info… will show the following information: table type, pressure, fuel temperature, fuel composition, oxidizer temperature and oxidizer composition.
Improved robustness for incompressible fluids
In FINE/Open with OpenLabs 9.1, the pressure gradient switch is removed when computing the second order artificial dissipation for simulations using incompressible fluid. This improves the robustness of the simulations.
Fluid-Structure Interaction with modal approach
In FINE/Open with OpenLabs 9.1, FSI simulation with modal approach is now fully supported for single and multi-block projects. It also includes the weak and strong coupling methods.
The IDW mesh deformation is now also supported and has been replaced as the default method. Note that the mesh deformation based on quaternions has been removed as this method is deprecated
The following is the list of existing capabilities recently certified in FINE/Open with OpenLabs:
Model heat transfer in thin solid layer with non-zero thickness wall model
For some applications with a thin solid layer like a thermal barrier coating in the combustion chamber, meshing this thin layer requires a large number of cells. And consequently the simulation requires lots of CPU time. FINE™/Open provides a non-zero thickness wall model, which accounts for the heat transfer in the thin solid layer without the need to mesh it.

The resolution of Computational Fluid Dynamics (CFD) problems involves three main steps:
- spatial discretization of the flow domain,
- flow computation,
- visualization of the results.
To perform these steps NUMECA has developed three software systems. The first software system, HEXPRESS, is an automated all-hexahedral unstructured grid generation system. HEXPRESS also includes a module HEXPRESS/Hybrid, which allows to mesh complex geometries with an isotropic hybrid mesh including mainly hexahedral cells with tetrahedral, pyramid and prism cells. The second software system, FINE/Open with OpenLabs, is a powerful CFD Flow Integrated Environment dedicated to complex internal and external flows. The third software system, CFView, is a highly interactive Computational Field Visualization system.
These three software systems have been integrated in a unique and user friendly Graphical User Interface (GUI), called FINE/Open with OpenLabs, allowing the solution of complete simulations of 3D internal and external flows from the grid generation to visualization, without any file manipulation, through the concept of a project. Moreover, multi-tasking capabilities are incorporated, allowing the simultaneous treatment of multiple projects.
FINE/Open with OpenLabs fully integrates the concept of multitasking. This means that the user can manage a complete project in the FINE/Open GUI; making the grid using HEXPRESS, running the computation with the FINE/Open solver and visualizing the results with CFView. Furthermore, the user has the possibility to start, stop and control multiple computations.
418M multidomain mesh automatically generated in 4.5 hiyrs with HEXPRESS/Hybrid. Full multiphysics CHT coupling with FINE/Open radiation and heat exchanger macro model.
Numeca International Inc develops computational fluid dynamics (CFD) software for the simulation, design, and optimization of fluid flow and heat transfer worldwide. It offers automated and customized flow integrated environments (FINE), including FINE/Turbo for the simulation of rotating and turbomachinery flows; FINE/Open for the simulation of complex internal and external applications; and FINE/Marine for marine applications.

Multiprocessors calculations
Multiprocessors calculations are allowed on shared and homogeneous distributed platforms. Non-homogeneous configurations are not allowed.
The following limitations additionally apply:
- Multiprocessors calculations are allowed on distributed platforms in local user configurations provided that the same account is used for all machines,
- Domain administrators are not allowed to run multiprocessors calculations.
- MPICH2 library needs Microsoft .net Framework package before installing NUMECA software otherwise execution of mpiexec.exe will lead to a Windows error message.
Hardware requirements
Next to the standard hardware (monitor, keyboard and mouse), some specific recommendations apply in the use of NUMECA software:
- a mouse with scroll wheel is strongly recommended.
- the monitor should support 24-bit color graphics and have a 1280 x 1024 pixel resolution for adequate visualization.
- an Ethernet card should be installed and properly configured.
- NUMECA Software does not support CXFS (Clustered XFS) and IBRIX disk file systems.
Memory and disk space requirements
The Random Access Memory (RAM) required to run NUMECA software depends upon several factors, in particular including the number of grid points inserted in the grid, the physical models selected (turbulence, adaptation,…), the introduction of non-matching boundary conditions and the selected calculation mode (mixed or double precision).
Similarly, a minimum disk space is required on the hard disk to allow the storage of the project files. The size of these files largely depends upon the number of grid points generated.
More product specific details
HEXPRESS
The use of minimum 1 GB RAM is strongly recommended. As a general guideline, about 0.5 to 0.7 GB RAM are required to run a one million nodes project. The suggested swap space should be equivalent to at least 3 times the RAM installed.
As a general guideline, a minimum of 300 MB is required to store the project files (provided that the geometry is not defined by Parasolid™ or CATIA files) for a one million nodes project.
HEXPRESS/Hybrid
The Random Access Memory (RAM) required to run HEXPRESS™/Hybrid depends upon several factors. In particular, the complexity of geometries and the settings of the CONF file. As a general guideline, the Random Access Memory (RAM) required to run HEXPRESS™/Hybrid are:
- for mesh without viscous layers - between 500 MB and 700 MB RAM per million of cells
- for mesh with viscous layers - between 700 MB and 900 MB RAM per million of cells
The use of minimum 4 GB RAM is mandatory, but the installation of 8 GB is recommended. The suggested swap space should be equivalent to at least three times the RAM installed.
About 1 GB is required to store a two million nodes mesh in SPH format.
OpenFINE/Open with OpenLabs
The use of minimum 1 GB RAM is mandatory, but the installation of 2 GB is recommended. As a general guideline, about 1.5 GB RAM is generally required to run a one million nodes project in double precision mode. The suggested swap space should be equivalent to at least 3 times the RAM installed.
Mesh partitioning for parallel computations requires about 1 GB memory per million cells. When using serial partitioner, the user must ensure that the memory on the head node is sufficient, because the partitioning is performed only on the head node in case of serial partitioning.
As a general guideline, a minimum 1.4 GB is required to store the mesh and solution files (one file, no full non-matching connections, solution stored after one iteration) when running a one million nodes project.
CFView
The use of minimum 1 GB RAM is strongly recommended. As a general guideline, about 250 MB RAM are required to visualize a one million nodes project. The suggested swap space should be equivalent to at least 3 times the RAM installed.
No specific disk space is required on the hard disk for CFView except if images or data files are saved or if the meridional average is created in CFView (turbomachinery application).
Graphics requirements
NVidia graphics cards are fully supported, installed together with the latest drivers.
NUMECA software makes use of the advantages of the available Graphics Card. Some trouble may however come up with the default driver OPENGL since it may not be supported by the user host computer and machine display. In order to set the system compatible with a more portable driver, typically MSW driver is used under Windows instead. Note however that the proposed drivers are usually less efficient in terms of graphical speed than the default driver.
Compilation requirements for OpenLabs
Customization of the CFD models using OpenLabs requires the possibility for compilation.
On Windows 64 bit, Microsoft Visual C++ Build Tools 2015 must be installed: make sure to select the component Windows 10 SDK 10.0.10240 during the installation.
