AcuSolve Command Reference Manual
AcuSolve command descriptions and corresponding examples.
- Command Format
  The commands have the following general syntax.
- Command Qualifier
  Some commands require a qualifier. The qualifier is used to distinguish one use of the command from another.
- Parameter Format
  Each command may have zero or more parameters. Most command parameters have default values.
- Parameter Operators and Functions
  Parameter types of integer, real, and array may be any valid arithmetic expression. Valid expressions consist of the operators +, -, *, /, ^ (for power), parentheses, a set of built-in functions and a set of built-in or user-assigned variables, specified by the ASSIGN command.
- File and Data Format/Reading Data From Files
  AcuSolve input file supports two mechanisms for entering list and array data.
- Alternative Command Organization
  In the rest of this manual the commands are grouped into general categories and placed into chapters. In order to make a particular command functionality easier to find, an alternative categorization is presented. Each command may appear in more than one category.
- Global Commands
  This section contains the commands that define the global description of a problem or provide data that can be used globally.
- Solution Strategy Commands
  The solution strategy of a problem is specified by the commands in this section.
  - ALGEBRAIC_MULTIGRID_PARAMETERS
    Specifies parameters for the algebraic multigrid algorithm.
  - AUTO_SOLUTION_STRATEGY
    Automatically creates the solution strategy by issuing all the other commands in this chapter.
  - CONVERGENCE_CHECK_PARAMETERS
    Specifies the parameters for fine tuning convergence checking.
  - LINEAR_SOLVER_PARAMETERS
    Specifies the parameters for fine tuning the linear equation solver.

Solution Strategy Commands

The solution strategy of a problem is specified by the commands in this section.

Either use the AUTO_SOLUTION_STRATEGY command which issues all the other commands in this section or use those commands individually. If the AUTO_SOLUTION_STRATEGY command is not used then the TIME_SEQUENCE and STAGGER commands must be explicitly given in an input file. All others are optional; if they are not given, their default values are used. Explanations of the relationships between these commands and the overall time stepping and nonlinear iterative strategies are given in the TIME_SEQUENCE command.
