NUMECA Fine / Marine 9.1 | 1.5 GbNUMECA International is delighted to announce the official release new version of FINE / Marine simulation software. Release 9.1 - the faster convergence, same accuracy - and plenty of other improvements. New in FINE / Marine 9.1
Dynamic evolution of non-linear iterations and under relaxation coefficients during the acceleration phase of the boat has been implemented to get 25% of speedup, without any penalty on accuracy.
Convergence checker now interfaced
To avoid useless CPU time when the computation is already converged, the solver automatically stops the simulations when the physical quantities are converged. This interesting tool is now interfaced with smart default values to save time.
4 new demo cases have been added to the documentation package to illustrate the maneuvring operations: roll damping, zig-zag, turning circle, and course keeping are now part of the standard simulations of FINE/Marine. Also, 1 democase for seakeeping based on the Tokyo Workshop 2015 has been added.
Extension of the self-propulsion plugin to double screwed ships
The plugin dedicated to self-propulsion with modeled propellers in sliding grids has been extended to double screwed ships.
Several C-Wizard improvements
- Impose vertical center of gravity and let the C-Wizard calculate the longitudinal one
- Successive restarts now handled with relative time
- Convergence checker incorporated to save CPU time
- Seakeeping improvements to decrease number of cells and use ITTC inertia matrix
That’s not all!
- A new time step law to automatically define the time step in case of sliding or overset grids
- The possibility to handle ducted propellers from our Rhino3D plugin
- The improvement of the forces by section plugin in CFView to handle radial, tangential and axial forces distribution like for instance on propellers.FINE / Marine , The Leading CFD Software for Naval Architects and Marine Engineers – FINE / Marine is a unique integrated CFD software environment for the simulation of mono-fluid and multi-fluid flows around any kind of ships, boats or yacht including various types of appendages.

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:
The use of minimum 2GB of RAM is mandatory, but the installation of 8 GB is recommended. As a general guideline, about 2 GB RAM is generally required to run a one million nodes project. The suggested swap space should be equivalent to at least three times the RAM installed. For parallel computations, a multi-processors environment with 2GB of RAM per core is recommended. In such case the suggested swap space should be equivalent to at least one time the RAM installed.
Mesh conversion and partitioning for multi-processor calculations requires about 1 GB per million cells. Since mesh partitioning cannot be performed taking benefit of multi-processor environments, access to nodes allowing large RAM (from 4 to 16 GB) may be mandatory during mesh partitioning.
As a general guideline, about 1.6 GB is required to store a one million nodes mesh, with flow solution on disk. The minimum storage is fixed as 400 MB per million cells, but this only guarantees proper restart procedures without direct possibilities for the visualization of the flow solution.
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.
