Modeling and reconstruction of Temperature, Wind, and Atmospheric Pressure fields in a 2D area from the information provided by the cartography of the interested region.

Abstract

[Abstract] In the present work, the temperature, wind, and atmospheric pressure elds were calculated in a two- dimensional area by using a model for laminar and incompressible ow with heat transfer. The Navier- Stokes and energy equations were numerically solved by using nite element methods with Fenics, which is an open-source computing platform for solving partial di erential equations. The computational domains were generated with Gmsh; an open-source nite element mesh generator with a built-in CAD engine and post-processor. The code was validated by comparing the nite element solutions with known problems studied by other authors. More complex domains were generated from a topography dataset provided by OpenTopography and the code was run imposing more realistic boundary conditions, such as velocity and temperature pro les. A work ow was developed to show the steps to generate the physical domain from a dataset since, together with a Python script, it solves the model for laminar and incompressible

ow with heat transfer in the selected area.
