# Solve

The solve command is used to solve the problem after reading the data and initializing the variables.

Syntax

solve "solver"

Valid entries for solver are: GMRES and Sparse

Sparse |
A direct solver used for solving smaller problems |

GMRES |
An iterative solver mainly used for solving large problems (degrees of freedom > 1 000 000). |

Comments

When invoking the solve command for the first time, you have the option to initialize the flow field. This can be done by adding extra options to the solve command. The following table gives the syntax for each option.

## Initial Guess Type |
Syntax |

## Inflow (default) |
pset GuessType Inflow solve "solver" |

## Constant |
pset GuessType Constant pset InitialGuess {U_vel V_vel W_vel Pressure Temperature Strain} solve "solver" |

## Compute |
pset GuessType Compute solve "solver" |

## None |
solve "solver" This uses zero for initial guess |
