# AcuSolve Input File Structure

AcuConsole is the graphical user interface (GUI) wrapper for the AcuSolve solver.

After launching AcuSolve a folder is written out named MESH.DIR containing mesh files and an input file containing the solver commands. This input file can be edited directly for any appropriate changes in the problem. The commands have the following general syntax.
COMMAND (qualifier){
Parameter1=value1
….
parameterN = valueN
}
Where COMMAND is the name of the command, such as ANALYSIS or MATERIAL_MODEL, qualifier is a mandatory qualifier of the command, parameter1 to parameter are the optional parameters of the command and value1 to valueN are the corresponding values of the parameters. Below is the description of a simple pipe flow with the comparison between GUI and input file commands.
