File Relations
Below a reminder of the relation between the filetypes used by both dolfyn and its preprocessor.
The demo file(s) can be found under .\dolfyn\demo. You can also download them seperately from our Downloads page.
Unpack the *.gz files belonging to the case you wish to run, in our case:
demo.bnd.gzdemo.cel.gzdemo.vrt.gz
Create Geometry File
Create a geometry file using the preprocessor and the following inputs:
dolgeo
Dolfyn PreProcessor
Input casename:
demo
Using demo as input
Opening vertex file
.
.
.
Enter scaling factor (1.0):
1.0
Using: 1.00000000
Enter format of geometry file (bin|ascii):
bin
Dump binary geometry file
Done
The result is the geometry input file for dolfyn demo.geo.
Editing Inputs
Optionally, the input file demo.din may be edited, with your preferred text-editor.
This file contains all control parameters, material properties, and boundary conditions for the simulation.
Run dolfyn
Now start dolfyn and select the demo case:
dolfyn demo
This is dolfyn version 0.607

Done demo
Bye!
The results are stored in demo.odx and in demo.vtk.
