DMAP Module Features
DMAP is a capability of MSC.NASTRAN that enables you to alter and create your own solution sequences.

DMAP stands for Direct Matrix Abstraction Program. DMAP is a high-level language with its own compiler and grammatical rules. DMAP statements contain data blocks and parameters, and operate on them in a specified manner. For example, the DMAP statement

• ADD U1,U2/U3 $
  adds matrices U1 and U2, and calls the output U3, or

• MATPRN U3// $
  prints the matrix U3.

• Add, subtract, multiply, and transpose
• Solve simultaneous equations (decomposition and forward-backward substitution)
• Merge and partition
• Compute eigenvalues

• Finite element postprocessors
• Kinematics programs
• Test-analysis correlation programs

• Matrix arithmetic
• Database operations
  • Store to the database
  • Fetch from the database
• Data flow via structured programming
  • IF-THEN-ELSE
  • Jumps, loops

• Coupled dynamic analysis
• Cross-orthogonality between test and analysis eigenvectors
• Propeller whirl analysis
• Frequency-dependent impedance
• Dynamic model checkout
• Analysis of rotating structures (including gyroscopic effects)
• Dynamic analysis method of shipboard equipment (DDAM)

• Because the solution sequences are written as a series of DMAP statements, some errors can be corrected by modifying the solution sequences with DMAP statements provided by MSC in the Current Error List.
