Catchwords

transformation of coordinates
FE mesh
structure information and polygones

Short Description of Functionality

The program DREHE2D transformes coordinates of FE meshes, structure files, polygone files and sounding files by application of translation, rotation and (optional) mirror. A reverse transformation is possible too.

Input-Files

1. file of type gitter05.dat/bin or
2. file of type insel.dat or
3. file of type digi.gkk or
4. file of type nodes.save or
5. file of type poly.dat or
6. file of type frames.dat or
7. file of type rgz.dat
8. file of type geom.dat

with original coordinates.

Output-Files

1. file of type gitter05.dat/bin or
2. file of type insel.dat or
3. file of type digi.gkk or
4. file of type nodes.save or
5. file of type poly.dat or
6. file of type frames.dat or
7. file of type rgz.dat
8. file of type geom.dat

with transformed coordinates, a printerfile drehe2d.sdr and optional a terminal protocol of type gkslog.dat.

Methodology

The program reads the point (0,0) of the new coordinate system and the rotation angle from the terminal. If the coordinates shall be mirrored, a mirror axis is read, defined by an angle and a point of this axis. Then coordinate information of specified files is transformed to the new systemby translation, rotation and (optional) mirroring.

Remarks: If filetype frames.dat is transformed, only the center is transformed. Then a new frame of the given width and height is created. The new frame is not identical to the old one but can still be used as an orientation to find the old areas again in the new coordinate system.
The program session can be rerun a second time by using the terminal protocol.
