ansys.mapdl.core.Mapdl.nwrite

Mapdl.nwrite(fname='', ext='', kappnd='', **kwargs)

Writes nodes to a file.

Mechanical APDL Command: NWRITE

Parameters:

fnamestr

File name and directory path (248 characters maximum, including the characters needed for the directory path). An unspecified directory path defaults to the working directory; in this case, you can use all 248 characters for the file name. The file name defaults to Jobname.

extstr

Filename extension (eight-character maximum). The extension defaults to NODE if Fname is blank.

kappndint or str

Append key:

• 0 - Rewind file before the write operation.

• 1 - Append data to the end of the existing file.

Notes

Writes selected nodes ( nsel ]) to a file. The write operation is not necessary in a standard Mechanical APDL run but is provided as a convenience to those who want coded node file.

Data are written in a coded format. The format used is (I9, 6G21.13E3) to write out NODE, X, Y, Z, THXY, THYZ, THZX. If the last number is zero ( THZX = 0), or the last set of numbers are zero, they are not written but are left blank. Therefore, use a formatted read to process this file.

Coordinate values are in the global Cartesian system.
