ANSYS Fluent UDF Code Refinement

This UDF (User Defined Function) is designed to model the transpiration phenomena of tomato plants in a simulated environment using ANSYS Fluent. The UDF calculates thermal and moisture exchanges based on environmental parameters such as ambient temperature and relative humidity, considering the plants as porous parallelepiped blocks. The objective is to understand and simulate the impact of climatic conditions on the internal dynamics of the plants. The code initializes the internal temperature and water fraction within the domain's cells. It employs empirical and physical relations to estimate stomatal and aerodynamic resistances, heat flux, vapor pressure difference (DPV), and convection properties based on flow regimes (natural, mixed, or forced convection). The UDF also computes radiative absorption and total resistance to model the internal temperature and humidity of the plants. Thermal and water vapor sources are incorporated into the transport equations to capture energy and mass exchanges, while indices such as LAIV and the thermal properties of air are considered to describe the complex interactions between the plant and its environment.

He contractor will be responsible for correcting the UDF code I have written for Ansys Fluent 19.2. They will help me position each part of the code correctly within Fluent and ensure proper integration into the model. Additionally, they will need to add the necessary commands to enable the code to run in parallel, utilizing 8 processors. Currently, my UDF works only in serial mode (with a single processor).

Once the correction is made, the contractor will provide me with the corrected UDF code, ready to be used in parallel. They will also assist me in setting up the simulation and ensure everything works properly with the parallel code.
