isosurface plot for transient data
 
Hi All,

Is it possible show a example code of iso-surface from the transient data (*ccmt), such as temperature, species concentration (CO2, OH, etc)? It will be great, if you could add some explanation of the commands.

Also, how to know the which number indicates the piston surface, if I would like to show the concentration only on piston surface? refer to the following code.

!Collect the piston surface data into a cell set
ctable, 502, fluid
vset, newset, edge
cset, newset, surface, 263919
cmodify, cset
..
..
..
..
!Plot cell-averaged fuel scalar data on the piston surface
getcell, conc, 1
cset, newset, type, 502
caverage, cset
poption, cont
cplot


Thank you in advance.

you can try these commands,
bset newset region 6 ! see Define boundary|Define boundary region panel
vset newset bset
getw,...
cset newset vset all
cset subset shell
caverage, cset
poption, cont
wplot
...
OR
bset newset name region1_piston_crown
vset newset bset
getw,...
cset newset vset all
cset subset shell
caverage, cset
poption, cont
wplot

Thank you very much for the help. It works perfectly.

Any idea about the iso_surface plot???:D

popt, isos, value

where value is the numeric value for the isosurface

lunar1984 May 15, 2013 20:16

I am new in STARCD. In order to understand the command efficiently, any example you can offer?

Good to see both of you guys here. I believe you guys are the most active and experienced.:)

Enter the command "help popt" & read the results.

popt sets the plotting option
isos reguests an iso-surface
value is the vaule of the iso-surface

I believe you need to have vertex data loaded before you create an iso-surface. If you don't understand what I mean by vertex data, read more of the manual. Then use the getv command to load the data you want to view. So:

getv vmag
popt isos 40
cplo

would give you an iso-surface for velocity magnitude 40.

Or you can click a bunch of stuff in the Nav-Center....

Thank you very much for the explanation. :)
btw, what is the nav-center?? research institute?? company? or cfd group?

Sorry, the Nav-Center is the old name for what is now labeled pro-Star Model Guide.
