intyp

The intyp command chooses the interpolation James uses where a script has not asked for one.

Syntax

intyp <option>

option is 1 for linear interpolation or 2 for transfinite interpolation. The default is 1.

What it does

Where no lin or tf command reaches a face or a block, James fills in its interior by the default. Option 1 uses linear interpolation, the kind lin asks for. Option 2 uses transfinite interpolation, the kind tf asks for, for faces and blocks. Edges are linear under either option.

When James applies it

When the part is meshed. James records the value in force when the part ends, and the setting stays for later parts until you change it. It is legal in any phase: Control, Part or Merge.

Rules James adds

Under intyp 2 a tf on a single region does nothing, because transfinite interpolation is already the default there. A single-region lin does change the result, because it forces the linear family onto a region that would otherwise be transfinite.
A missing value is E0220 reported at the intyp keyword.

Diagnostics

E0220: the option is not 1 or 2, or is missing.

Example

The script tests/corpus/112-mxp-intyp-syntax/input.tg, which make test runs:

mxp 2
intyp 2
block 1 2;1 2;1 2;0 1;0 1;0 1;
endpart

The IR holds intyp 2 on the part. An intyp 2 set inside the second of three parts gives that part and the third intyp 2 and leaves the first at intyp 1.
