To use FEMAP to post-process Fastflo results, an interface
program called ff2femap.exe is provided with Fastflo.
This utility converts Fastflo results into a FEMAP neutral
file, and needs two input files: mesh.dat and rhs.out.
mesh.dat is the mesh input file for Fastflo, while
rhs.out is the file produced by the command store V* (where
V* indicates the name of a vector). The command store
can also save data into other named files as directed (see the on-line
Reference Manual for details). As an example, the Fasttalk
command store V200 stores the values of V200 in the file
rhs.out.
With mesh.dat and rhs.out as the required input files, you
can now run the executable ff2femap.exe. This produces a single
output file, result.neu, in FEMAP neutral format.
result.neu contains both mesh information and vector data, and it can
be read directly by FEMAP for visualisation.
The steps below show how to obtain arrow plots and contours in
FEMAP.
save vector V* into the file rhs.out by the Fastflo
command store V*
run the executable ff2femap.exe using rhs.out and
mesh.dat as the necessary two input files; the output file is
called result.neu and is in FEMAP neutral format
start up the FEMAP window and pick the New Model button
at the prompt; a blank FEMAP environment now appears in the
FEMAP window
choose the File pull-down menu of the main tool bar and push
the Translate button
choose the FEMAP neutral format and click on the Read
button
at the prompt for file name, pick the result.neu file
FEMAP now reads in the mesh information and solution results
of the vector V* of Fastflo; vector V* is regarded
as Output Vector Data in FEMAP
choose the Create menu on the main tool bar and push the
Output button
select the Set pull-down button of Output and pick the
set for which vector data is to be plotted. (Fastflo data in
rhs.out is stored in one or two vector sets and
ff2femap.exe places this data into one vector set.)
push the OK button on the Set pull-down menu
within the Output menu, pick the Vector button and push
OK
choose the View menu under the main tool bar and click on
Select
pick the Vector option of the Deformed Style pane
pick the Contour option of the Contour Style pane
push the Deformed and Contour Data button
in the Output Set pane, choose the name of the data set
in the Output Vectors Deformation pane, write the component of
the vector in the set (for example 3 will display 3D arrow plots)
in the Output Vectors Contour pane, write the component of the
vector in the set (for example 4 will display pressure in a 3D
calculation)
push the OK button of the Deformed and Contour Data menu
vector arrows and contour surfaces will appear together on screen
For more information on vector data, users of FEMAP are referred to
the List menu under the main tool bar.
