Compilation

type >> make -j 16, in order to compile the code both in your workstation or Supercomputing Wales (hereafter SCW). To recompile type >> make clean, and then >> make -j 16. To add/remove compilation flags, see “makefile” file.

Source code

Some important source files:

  • fdstag.for (i.e. Finite Differences Stages) and flosol.for (Flow Solver) indicate the sequence followed by Hydro3D to allocate variables, advance the Navier-Stokes equations in time, etc.
  • imb.for computes the immersed boundary method subroutine,
  • DeltaF_MLS.for computes shape functions
  • shapes.for generates the geometries and also computes the new coordinates when the solid moves.
  • roughness_function.for generates rough bed.

Hydro3D in Supercomputing Wales

There are two modules that need to be loaded in order to compile Hydro3D:

  • module load compiler/intel/15.0/3.187
  • module load mpi/intel/5.1/3.210

Tecplot

Output files are in tec360 format. In order to get the license, once you install tec360, select “Network license” and type: 10.74.7.131 and 27100 in the IP and Port numbers respectively. This has to be done at School of Engineering connected to internet. If you are going to use tec360 away from the University, once you activate the license, select in Help>Roaming the latest day available. This option will give you access to tec360 without internet connection.

Acknowledging Supercomputing Wales in academic papers

It is vital to add a sentence on the support we receive when running in SCW. Please, add the following sentence in the Acknowledgements section of your journal/conference paper:

We acknowledge the support of the Supercomputing Wales project, which is part-funded by the European Regional Development Fund (ERDF) via Welsh Government.
