1. A computer-implemented method for predicting airflow within a data center using a potential flow technique, the method comprising: automatically generating, by a computer, an unstructured grid, the unstructured grid comprising a plurality of unstructured grid cells, each unstructured grid cell having a size; dividing, by the computer, a representation of the data center into the plurality of unstructured grid cells; determining, by the computer, airflow velocity values for each of the plurality of unstructured grid cells using airflow velocity potentials; determining, by the computer, a temperature value for each one of the plurality of the unstructured grid cells using the airflow velocity values; determining, by the computer, a concentration value for each of the plurality of the unstructured grid cells using the airflow velocity values; and calculating, by the computer, a comparison result indicating whether the concentration values, the airflow velocity values and the temperature values for the plurality of the unstructured grid cells satisfy convergence criteria.
