hm_diffencodings

Calculates the distance between two lists of encoded strings representing shapes of geometries.

Syntax

hm_diffencodings encodings1 encodings2 ?<option1>=<value1>? ?<option2>=<value2>? ... ?<optionN>=<valueN>?

Type

HyperMesh Tcl Query Command

Description

Calculates the distance between two encoded lists representing shapes of geometries. The geometries can be CAD, FE or a mixture. Typically this is the Euclidean distance normalized by the number of entries in the encoding. The encodings are generated by hm_encodeshape.

Inputs

encodings1: The first list of encodings generated by hm_encodeshape.
encodings2: The second list of encodings generated by hm_encodeshape.

encoding_algorithm: The optional encoding algorithm to use. Valid values are:; 0 - Spherical harmonics (default)

sphhar_bandwidth: Optional, valid for encoding_algorithm 0, default 16.

sphhar_fallof: Optional, valid for encoding_algorithm 0, default 2.828427.

sphhar_radii: Optional, valid for encoding_algorithm 0, default 32.

sphhar_resolution: Optional, valid for encoding_algorithm 0, default 64.

Examples

To calculate and diff the encodings from all surfaces against all elements:

*createmark surfs 1 all
set x [hm_encodeshape surfs 1]
*createmark elems 1 all
set y [hm_encodeshape elems 1]
hm_diffencodings $x $y

Errors

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:

if { [ catch {command_name...} ] } {
   # Handle error
}
