Main Analysis Header

These commands define the type of analysis (FEA or MPM) and make a few other settings.

These commands are used the annotate the output results:

XML Commands

Two developer options can be added to the main header using an XMLData command block:

XMLData "Header"
  <RandSeed>5739<RandSeed>
  <DevelFlag Number='4'>1<DevelFlag>
EndXMLData

If RandSeed is greater than zero, it seeds the random number generator with that constant. This change makes stochastic modeling reproducible (each run gets the same random numbers). It is helpful when setting up stochastic simulations, but must be removed when ready to get stochastic results. DevelFlag sets a developer flag (by number) that is only useful if working with source code and you want to temporarily activate some different option. The flag values must be integers.
