PhD Thesis by John Ewer.can be determined for the experimental set-up and so it is useful if this data can also be used inthe CFD code to accurately represent the fire. Again the policy with the prototype CFD systemis to limit the need for the user to write source code to extend the CFD capabilities so a generaltable file handling volume source has been defined which allows the simple use of time varyingtabular source data to be read in from a file.4.3.14 Run-time modification of volume source application regionA recent idea has been to allow the user to simulate fire spread by extending the volume overwhich the fire load is applied. At present there is no automated means to spread the fire withinthe prototype system however the first step is to provide a manual method of enlarging the firevolume so that a reliable automated methodology can be found.4.4 Summary of chapterThis chapter has described the considerations and implementation details that were used totransform the re-engineered CFD framework into a vehicle for interactive control research. Oncethe new interactive CFD system had been completed it was necessary to verify that the reengineeringprocess and subsequent prototype developments had left the original functionalbehaviour, of the legacy CFD system, unchanged. The following chapter (See Chapter 5)describes a sufficiently wide coverage of test cases, and their results, that were used to verifythat the whole of the new software framework was consistent with the original legacy software.4-84
