Source Code:

• tec_write.f90, the source code.

Examples and Tests:

• tec_write_test.f90, a sample problem.
• mydata.txt, a data file to be used.
• tec_write_test.txt, sample problem output.

One example shows how to read a data file that represents a slice of cylindrically symmetric data, and write it out in TECPLOT format:

• mydata.txt, a data file to be used.
• cylinder_3d.dat, the data, reformatted for TECPLOT as a 3D cylinder, made by making many copies of the plane.
• plane_slice.dat, the data, reformatted as a plane slice for TECPLOT.

Data files created by the sample problem include:

• cylinder.dat, a 3D cylinder version of the data.
• cylinder_slice.dat, the data, treated as a 2D slice.
• channel.dat, a 2D channel flow, one time step.

List of Routines:

• GET_UNIT returns a free FORTRAN unit number.
• R8VEC_EVEN returns N real values, evenly spaced between ALO and AHI.
• TEC_WRITE_OPEN opens a TECPLOT output file.
• TEC_WRITE_CLOSE closes a TECPLOT output file.
• TEC_WRITE_HEADER writes the two line TECPLOT header.
• TEC_WRITE_XY_LINE writes out line data in XY geometry for use by TECPLOT.
• TEC_WRITE_XY_PUV writes out PUV data in XY geometry for use by TECPLOT.
• TEC_WRITE_T3 writes data defining 3 node triangular elements.
• TEC_WRITE_T6 rewrites 6 node triangular elements as 3 node triangles.
• TEC_WRITE_XY_UV writes out UV data in XY geometry for TECPLOT.
• TEC_WRITE_XY_PRUV writes out PRUV data in XY geometry for TECPLOT.
• TEC_WRITE_XY_UVW writes out UVW data in XY geometry for TECPLOT.
• TEC_WRITE_CYL_V writes out V data in cylindrical geometry for TECPLOT.
• TIMESTAMP prints the current YMDHMS date as a time stamp.
• TVEC_EVEN3 computes an evenly spaced set of angles between 0 and 2*PI.
