ReadSubzoneTecplot

read SZL (Sub-Zone Load-on-demand) Tecplot data

Purpose

The ReadSubzoneTecplot module reads Tecplot 360 Sub-Zone Load-on-demand (*.szplt) data from a directory. Only structured (ordered) zones are supported. All .szplt files found in the input directory are considered according to the selected time-step range and step increment.

Ports

ReadSubzoneTecplot grid_out grid or geometry (grid_out) field_out_0 data field (field_out_0) field_out_1 data field (field_out_1) field_out_2 data field (field_out_2) field_out_3 data field (field_out_3) field_out_4 data field (field_out_4)

  • grid_out — structured grid (all subzones)

  • field_out_0 .. field_out_4 — data fields chosen by the user (up to five).

The first output port (grid_out) provides the structured geometry. The remaining ports provide solution fields selected via the module parameters.

Parameters

name

type

file_dir

name of szTecplot files directory

String

static_geometry

Freeze blade geometry (0 = dynamic, 1 = static from reference timestep)

Int

static_ref_timestep

Timestep index to take the static geometry from (0-based)

Int

tecplotfield_0

This data field from the tecplot file will be added to output port field_out_0.)

String

tecplotfield_1

This data field from the tecplot file will be added to output port field_out_1.)

String

tecplotfield_2

This data field from the tecplot file will be added to output port field_out_2.)

String

tecplotfield_3

This data field from the tecplot file will be added to output port field_out_3.)

String

tecplotfield_4

This data field from the tecplot file will be added to output port field_out_4.)

String

Supported Reader Parameters

name

Supported System Parameters

name

description

type

_openmp_threads

number of OpenMP threads (0: system default)

Int

_benchmark

show timing information

Int

_concurrency

number of tasks to keep in flight per MPI rank (-1: #cores/2)

Int

_prioritize_visible

Int

_validate_objects

Int

The meaning of these parameters is described in more detail in the System Parameters documentation.

Behavior

  • If static_geometry is enabled, the grid is loaded once from the specified reference time step (static_ref_timestep) and reused for all output timesteps.

  • If static_geometry is disabled, the geometry is reloaded for each requested timestep.

  • Data fields are attached to the corresponding field_out_* ports only if the selected field exists in the file/zone; missing fields are skipped.
