60. CFD Inputs and Boundary Conditions

The CFD Inputs page is a practical helper for preparing solver-side freestream and near-wall inputs. It does not write solver configuration files directly, but it calculates the values you typically need when setting up a case.

CFD Inputs page with freestream, turbulence, and wall-distance helpers.

61. Inputs

The page takes:

  • Reynolds number

  • chord length

  • angle-of-attack range and step

  • turbulence intensity

  • turbulence length scale

  • static pressure

  • temperature

  • target flat-plate y+

62. Calculated Outputs

From these inputs, PyAero derives:

  • density

  • dynamic viscosity

  • kinematic viscosity

  • freestream velocity

  • u and v velocity components over the selected angle-of-attack range

  • target first-cell wall distance for the selected y+

  • turbulence kinetic energy

This is especially useful when you are trying to align the near-wall mesh size with a target solver setup.

63. Copy Workflow

The results are shown in a text panel and can be copied to the clipboard. This makes the page convenient as a solver-prep scratchpad even though PyAero itself is not the CFD solver.

64. Typical Use

Use this page when:

  • you want a rough first-cell estimate before meshing

  • you want to translate a Reynolds target into a physical freestream velocity

  • you need quick u and v components for a sweep of angles of attack

  • you want a convenient copyable summary for a solver case setup
