iscrete blocks when exporting the model to Ansys software.
The process of launching the simulation in the Solution section depends on the
computer configuration, for low-configuration machines it will run the simulation with a

longer time and give inaccurate results, so this leads to asynchrony. in exporting results
among group members.
The research team has several recommendations:
Research on thermal comfort factors will improve the distribution of the temperature
field in the conditioned room. Rearrange the sitting position of the worker. Indoor
environment conditions need to be care more, especially the amount of CO2 and moisture.
In addition, although simulation is a very useful method, it is still necessary to
realistic and experimental models to get the best results.
