ANSYS ICEM CFD™ OCTREE Tetra Mesher Parameters

tetra parameter_file [ -basic ] [ -nproc nprocessors ] [ -test_memory ]

The contents of  parameter_file are described below.
 

Command line options

-nproc nprocessors
    Tells tetra to use nprocessor processors.

-test_memory
    Tell tetra to allocate memory 1 megabyte at a time, printing messages as it does, until it can no longer allocate memory. With this option the mesher does no meshing. This is only to diagnose memory allocation problems.

Parameter file contents

Required

SurfaceFile tetin_file
    Tetin_file is the pathname to the file that has the description of the CAD model to be meshed.

DomainOutputFile domain_file
    Domain_file is the pathname to the domain file that will have the output tetra mesh.
 

Optional Tasks

    By default the tetra mesher reads the tetin file; creates an octtree mesh satisifying the size requirements in the tetin file; then moves nodes, and splits and swaps edges until the mesh represents the geometry and then writes the mesh to the domain file.

OnlySubdivide 0|1

    If this is specified with the value of 1 then the mesher will skip the step of moving nodes, and spliting and swapping edges. Default is 0

run_cutter 0|1

    If this is specified with the value of 1 then then after the mesher has completed meshing the geometry it will determine which elements are outside the object and for the elements inside the object it will determine the correct family of the element. Cutter also determines which faces should be represented by shell elements and for those shell elements which family they should be in. Cutter also determines which edges should be represented by bar elements and which family they should be in.
This is only available in releases >= 4.2. Default is 0

run_smoother 0|1

    If this is specified with the value of 1 then after meshing the object and possibly running the cutter,  the unstructured smoother will be run. This is only available in releases >= 4.2. Default is 0.

smoother_aspect value
    If run_smoother is 1 (see above) then this value is used to determine which elements should be smoothed. Only elements with quality below this value will be smoothed. Default is .3 .

smoother_n_iter value
    If run_smoother is 1 (see above) then the smoother is run for this number of iterations. Default is 10.
  

Parallel Processing

n_processors n_processors
    On shared memeory multiprocessors this value determines how many processors to use. If not specified all of the processors on a machine will be used.

    At this time distributed memory processing is not available.

Debug

InteractiveSplit 0|1

    If a value of 1 is specified the tetra mesher will stop periodically and present the user with a command prompt that allows the user to interorgate the mesh being created. Default 0 .

RemoteHost host_name

    If InteractiveSplit is set to 1 then host_name can be set to the name of the machine where the debug graphics display list will reside. The best choice is the machine where the graphics will be displayed.

WindowSize percent_of_window

    If InteractiveSplit is 1 percent_of_window is the size of the debug graphics window as a fraction of the screen. Value should be between 0 and 1. Default .5.

Misc.

OverwriteBoco 0|1

    If the value specifed is 1 and no boco was specified in the input tetin file, the tetra will make a boco file from the family_boco file specified.

CacheIntersections 0|1
    Obsolete. Default 0
 

binary
    Obsolete.
