Programming DMAP in MSC.Nastran™ Direct Matrix Abstract Programming will teach you from the ground up how to write programs in the native language of MSC.Nastran™. DMAP is an acronym for Direct Matrix Abstract Program, a symbolic, macro-like programming language used to control the way in which problems are solved in the MSC.Nastran™ finite element solver. You will learn how the solution sequences carry out the series of steps executed when solving a finite element problem. You will learn the language of the MSC.Nastran™ database, as well as carry out customised operations in a matrix toolbox designed for handling huge data structures. You will learn how to manipulate data in OUTPUT2 and OUTPUT4 files as well as discover the NDDL, the Nastran Data Definition Language. Assuming little or no programming experience, the rich features of the DMAP language are illustrated with numerous examples of DMAP code.

Anyone working with DMAP should have this book. In fact if you’re not working with DMAP, but just figuring out how to read and write OUTPUT2 and OUTPUT4 files it would easily be worth its price. This is by no means a replacement for the DMAP Programmer’s Guide, and has almost no coverage of individual DMAP modules. What it does very well is to explain the concepts behind DMAP. I’ve been writing DMAP alters for 25 years, and there’s a lot in this book about the internal data structures in Nastran that I didn’t know and would have done well to have known. The only additional comment that I’d make is that there’s very little about this book that’s exclusive to MSC.Nastran as opposed to NX Nastran. The only thing that I saw was the UDMSRV module, which was added in MD Nastran V2010 and does not exist in NX Nastran. Otherwise, someone programming in NX Nastran DMAP would find this book equally useful. I will purchase a 2nd copy to ensure that I always have mine close at hand ;-). Thank you...

REVIEW OF MARK ROBINSON'S DMAP BOOK I will give this an almost unqualified recommendation. The one glaring omission is a link to the web site that supports DMAPers, http://tech.groups.yahoo.com/group/nastrandmap/ I'll write a full review in August, after I return from vacation and use the book on some DMAP that I'm developing. I'll publish the review at the web site above.
