Description
Technical field
The present invention relates to a kind of file leading-in techniques, more particularly to one kind annulus cylindricality geometry mould in Tecplot softwares
The introduction method of type, belongs to computer software technical field.
Background technology
The Tecplot groupwares are the powerful data analyses and visualization released by Tecplot companies of the U.S.
Software is managed, in engineering and scientific research, the application of the Tecplot groupwares is increasingly extensive, and user is throughout aerospace, state
The scientific research institutions such as the industry such as anti-, automobile, oil and hydrodynamics, thermal conduction study, geoscience.It is aobvious as powerful data
Show that tool, Tecplot provide abundant drawing format.Tecplot is by drawing x-y curve graphs, the 2-D of multiple format
It draws and 3-D volume renderings with the faces 3-D, to show engineering and science data.
In general, business numerical simulation software has the interface to match with Tecplot softwares, as Fluent, CFX,
Numeca etc. need to only export the file format with Tecplot Software matchs, in Tecplot softwares just after the completion of calculating
It can realize the post-processing of result of calculation.But business numerical simulation software has limitation, for the simulation essence of certain problems
Spend poor, result of calculation confidence level is not high, therefore many times needs to write calculation procedure, using suitable for this problem and precision
Higher numerical algorithm calculates to realize to simulate.In this case, result of calculation is only write on into file according to ad hoc fashion
In, it could successfully import in Tecplot softwares and be post-processed.
For the computational domain of rectangular parallelepiped form, realize that post-processing is relatively simple in Tecplot softwares, and for it
His irregular geometry realizes that process is more difficult.
Invention content
The purpose of the method for the present invention is to solve the interface problem of annulus cylindricality geometrical model and Tecplot softwares, carry
A kind of method that annulus cylindricality geometrical model imports Tecplot is gone out.This method will directly calculate space coordinate and variable output,
The coordinate system conversion that physical space is carried out after importing in Tecplot, to realize the post-processing of annulus cylindricality computational domain.
Steps are as follows for the realization of this method：
A method of annulus cylindricality geometrical model data file is imported into Tecplot softwares, is included the following steps：

After calculating completion, simulation result is exported with document form data, the document form data
Including .plt and .dat etc..It is as follows that file data exports processing mode：
If computational domain shares N grid nodes, N is positive integer.If (x, y, z) is the calculating space of an independent grid node
Coordinate.If it is corresponding variate-value at each grid node u, v ..., can be needed that relevant variable is arranged according to target problem.Its
In, variable x, y, z is positive integer, and u, v ... they are real number.
Mesh point coordinate and corresponding variate-value are arranged according to particular order：Using variable x as document format data
One row, variable y are arranged as document format data secondary series, variable z as document format data third, and variable u is as data text
Part format the 4th arranges, and so on.In first three columns, variable x changes first as interior cycle；Variable y is recycled as secondary,
Second changes；Variable z finally changes as outer circulation.
Later, the data file of generation is imported into Tecplot softwares, space coordinate (x, y, z) will be calculated and be converted to annulus
Column physical space coordinates (θ, r, ζ), wherein θ is azimuth, r is radial distance, ζ is height, to realize that annulus cylindricality calculates
The post-processing in domain.When carrying out coordinate system conversion, azimuth angle theta is corresponding with variable x, and radial distance r is corresponding with variable y, height ζ with
Variable z is corresponded to.
Advantageous effect
The method of the present invention is exported by will calculate space coordinate according to particular order and is imported into Tecplot, in conjunction with
The function that coordinate system is converted in Tecplot carries out coordinate conversion, to realize that the result of calculation of annulus cylindricality computational domain imports, is
