<div dir="ltr">Dear all,<div><br></div><div>Firstly, let me preface this post by apologising if this is not an appropriate place to make this post. If this is the case, please would someone let me know a more appropriate location.</div><div><br></div><div>I have included below a brief for a VTK software development project that we wish to contract a developer to work on.</div><div><br></div><div><div># Introduction</div><div><br></div><div>We would like a particle tracker developed in VTK (C++). The code must be very documented/commented and tested. The work will involve the development of a simple filter, and construction of a VTK pipeline with pre-defined inputs and outputs. The particle tracker must have a parallel processing implementation.</div><div><br></div><div># Project details</div><div><br></div><div>The particle tracker must:</div><div><br></div><div>* Be built using the latest repository version of VTK.</div><div>* Implement multithreaded parallel processing, dividing the work amongst CPU cores running on the same machine. The parallelisation should occur across particles, rather than across the Eulerian space.</div><div>* The implementation must use the new `LagrangianParticleTracker` filter, offering a completely configurable implementation of the Lagrangian Particle Tracking (LPT) algorithm, and creating a subclass of the `vtkLagrangianBasicIntegrationModel`.</div><div>* The `FunctionValues` method, at this stage, will simply move the particle position based on the underlying velocity field.</div><div>* The input velocity field should be read either from both an OpenFOAM (<a href="https://openfoam.org/">https://openfoam.org/</a>) dataset, using the `vtkOpenFOAMReader`, and also a `.vtk` file using the `vtkDataSetReader`. Example files will be supplied.</div><div>* The input velocity field will be split into three domains and how the particle moves will depend on the domain that the particle is in. Therefore, the `vtkLagrangianBasicIntegrationModel` subclass should take into account the current domain of the particle (this will be extended by us, so this functionality must be in place).</div><div>* The input particles will be evenly distributed over a circular plane.</div><div>* The `vtkRungeKutta45` class must be used in the integration model.</div><div>* Particle integration will terminate if exiting the flow domain.</div><div><br></div><div>The outputs of the code should be:</div><div><br></div><div>* The particle positions at every *n* milliseconds of the integration.</div><div>* Which domain the particle is in at each of these times.</div><div>* Whether the particle is 'live' or has been terminated by exiting the flow domain.</div><div><br></div><div># Contact</div><div><br></div><div>Submissions of quotes and direct enquiries should be made to:</div><div><br></div><div>Tom Hampshire (<a href="mailto:tom.hampshire@goldstandardphantoms.com">tom.hampshire@goldstandardphantoms.com</a>)</div><div><br></div>-- <br><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr">Tom Hampshire, PhD<div>Chief Information Officer</div></div></div></div></div>
