Detailed Description

Executes system calls, entered in the form of a string lists.

Calls can be made at the following points in the calculation:

every time step
every output time
end of the calculation

Example of function object specification:

systemCall1
{
    type        systemCall;
    libs        ("libutilityFunctionObjects.so");
    ...
    executeCalls
    (
        "echo execute"
    );
    writeCalls
    (
        "echo \*\*\* writing data \*\*\*"
    );
    endCalls
    (
        "echo \*\*\* writing .bashrc \*\*\*"
        "cat ~/.bashrc"
        "echo \*\*\* done \*\*\*"
    );
}

Usage

Property	Description	Required
`type`	type name: systemCall	yes
`executeCalls`	list of calls on execute	yes
`writeCalls`	list of calls on write	yes
`endCalls`	list of calls on end	yes

Note: Since this function object executes system calls, there is a potential security risk. In order to use the systemCall function object, the allowSystemOperations must be set to '1'; otherwise, system calls will not be allowed.
