This function object calculates the value and location of scalar minimim and maximum for a list of user-specified fields. For variables with a rank greater than zero, either the min/max of a component value or the magnitude is reported. When operating in parallel, the processor owning the value is also given. More...

Detailed Description

This function object calculates the value and location of scalar minimim and maximum for a list of user-specified fields. For variables with a rank greater than zero, either the min/max of a component value or the magnitude is reported. When operating in parallel, the processor owning the value is also given.

Example of function object specification:

fieldMinMax1
{
    type        fieldMinMax;
    libs ("libfieldFunctionObjects.so");
    ...
    write       yes;
    log         yes;
    location    yes;
    mode        magnitude;
    fields
    (
        U
        p
    );
}

Usage

Property	Description	Required	Default value
`type`	type name: fieldMinMax	yes
`write`	write min/max data to file	no	yes
`log`	write min/max data to standard output	no	no
`location`	write location of the min/max value	no	yes
`mode`	calculation mode: magnitude or component	no	magnitude

Output data is written to the file <timeDir>/fieldMinMax.dat
