7.21. triqfm: Calculate forces and moments on a .triq file

Calculate the integrated forces and moments on a triangulated surface. This can calculate the forces and moments on one or many subcomponents of the annotated surface triangulation and write all the results to parametrically named files.

Usage:
$ triqfm TRIQ COMP1 COMP2 [...] [OPTIONS]
$ triqfm -h
Inputs:

  • TRIQ: Name of annotated triangulation (TRIQ) file

  • COMP1: Name or 1-based index of first component to analyze

  • COMP2: Name or 1-based index of second component to analyze

Examples:

Calculate the forces and moments on the full geometry in "grid.i.triq", which is a solution calculated at Mach 0.75.

$ triqfm grid.i.triq --mach 0.75
$ triqfm -m 0.75
Options:
-h, --help

Display this help message and exit

--json JSON

Read options from commented JSON file called JSON

--triq TRIQ

Use TRIQ as unmapped input file {“grid.i.triq”}

--comps COMPS

List of components to analyze separated by commas

--tri TRI, --map TRI

Use a separate triangulation (Cart3D tri, UH3D, AFLR3 surf, IDEAS unv, or other TRIQ format) as a map for which triangles to extract; if used, the component list COMPS and config file CONFIG apply to this file

--momentum

Include momentum forces in total

-m MACH, --mach MACH

Use MACH as the freestream Mach number {1.0}

--Re REY, --Rey REY

Reynolds number per grid unit {1.0}

--Aref AREF, --RefArea AREF

Reference area for coefficient computation {1.0}

--Lref LREF, --RefLength LREF

Reference length for coefficient computation {1.0}

--bref BREF, --RefSpan BREF

Reference span for coefficient computation {LREF}

--xMRP XMRP

Set x-coordinate of moment reference point {0.0}

--yMRP YMRP

Set y-coordinate of moment reference point {0.0}

--zMRP ZMRP

Set z-coordinate of moment reference point {0.0}

--MRP MRP

Moment reference point {”XMRP, YMRP, ZMRP”}
