CFD Studies

I offer the completion of any step of your CFD process, that is:

  • ✓ Geometry simplification and repair.
  • ✓ Design of domain boundaries and refinement areas.
  • ✓ Generation of meshes, that can:
     
    • - be in 2D or 3D.
    • - contain prismatic layers.
    • - be tria/tetra, quad/hexa, cartesian or hybrid.
    • - have periodic conditions.
  • ✓ Computation of CFD cases.
  • ✓ Post-processing of CFD results.

To complete CFD studies, the following computational power is available:

  • - CPUs: 8 × 3.4 GHz
  • - Memory: 32 GB

Tools to perform such things can be:

How it works:

It's enough to give me the input data by mail or by any other way:

  • ➡ Geometry:
     
    • - CAD models (STEP, IGES, CATPart, SLDPRT, X_T, ...).
    • - For simple 2D geometries, text files containing point coordinates is enough.
  • ➡ Mesh specification:
     
    • - Type of mesh (tetra, hexa, hybrid).
    • - Maximum number of cells you want.
    • - Area of interest (so as to refine it).
    • - Viscous layer specifications.
    • - Desired constrains (eg. periodic boundary condition).
  • ➡ Case description:
     
    • - Fluid type.
    • - Physical entities to simulate (velocity, pressure, temperature, etc.).
    • - Input/output conditions.
    • - Desired constrains (eg. periodic boundary condition).
  • ➡ Description of data to extract:
     
    • - Pictures.
    • - CSV files.
    • - Integrated values.
    • - etc.

Automation

In case you plan to make a large amount of similar CFD computations, for example in the context of an optimization study, I offer the automation of any step of your CFD process, from geometry generation to post-processing.

The most typical case is the use of a configuration text file that you can adapt to your everyday needs along with a bash script to be launch on Linux, launching itself successively suitable softwares for each step (geometry, meshing, solving, post-processing) and transmitting data between them.

Such scripts can even take into account post-processing data to automatically adjust either the geometry or the CFD boundary conditions over an optimization loop.

Tools to perform such things can be:

How it works:

There are two options:

  • ➡ Use the scripts on your computers or servers.
  • ➡ Let me use the scripts.

In the first case, you have to install Linux first. Always choose the last Long Time Support (LTS) version if existing. Recommended distributions are:

  • ➡ On severs:
     
    • - CentOS
  • ➡ On personal computers:
     
    • - Linux Mint
    • - Ubuntu

I personnaly use Linux Mint 64bit, so installing the same distribution on your computer will reduce to zero the risk of differences during script executions.

The second step is to install the open-source software which will be used by scripts. The list of them depends on the tasks the script will have to complete.

Of course, I can help you make the installation of Linux as well as of necessary open-source softwares.

Development

For specific cases that you will face in the long-term, I can develop for you made-to-measure interactive programs, be it in command line or working through a graphical user interface, to view or manipulate any kind of data.

Tools to perform such things can be:
