User manual Version 10.0, June 2011 D3PLOT Testing for the presence of a given data component. One problem when post-processing data is that you cannot assume that a given data component will be present in a model database, as most output is switchable. The GetData() function will return values of zero for components that are not present, but will not issue any warning messages in the process. So in order to write robust scripts that will work with databases of unknown origin it is wise to use QueryDataPresent() to interrogate the database before attempting to extract data from components known to be optional. Special considerations when working with adaptively remeshed analyses When working with adaptively remeshed analyses you should bear in mind that each file family will almost certainly have a different number of nodes and elements, and that it is therefore extremely important to ensure that the item indices you are extracting are valid for the current state. To be on the safe side it is best to obtain the "number of" items every time you change state numbers. In addition there is no guarantee that node or element <i> in family #1 will be the same in family #2. Exercise great care when extracting data from multiple families! Page A.39
