In this case, a 2D planar mesh should be displayed without displaying the surface hatchings.
How can the default hatching in the surface display be suppressed?
This hatching also gets displayed on postscript outputs of ICEM, where it is even less desirable.

The lighter lines in this image are the meshing lines. The darker lines are the surface hatching lines. How can these hatching lines be eliminated?

In the display tree (left side of the ICEM CFD window), you can right click on surfaces to change its display between wireframe, solid, transparent, etc.

You could also just left click to turn off surfaces.

This sort of thing is covered by the basic training and pretty much every tutorial. If you are having trouble here, I really suggest you hit a few tutorials or you will run into bigger difficulties later.

Thank you.
I do most of my ICEMing via scripts, (I am a Gambit refugee), and so was wondering how to accomplish just what you mentioned, though using script commands.
Also, is it possible to obtain postscript output while using ICEM in batch mode? Or are all display options ignored when running ICEM via its GUI?

Yes, I think it can be done, although I have not done it myself.

I did an earlier post about tdv commands (as opposed to the ic_commands you may be used to). Do a search for it.

Thank you.

I just did a search on your posts containing "tdv" but came up empty handed. However, I am quite curious as to what is possible with tdv commands.

Referring to the earlier reply, the tutorials are unavailable to me because these are only available on ANSYS's website with a login and password, not from within the program. I will ask my customer about whether he has the login and password requested there.

Replay control - save picture

I found this one. There may be others, but yes, the search on CFD-Online is pretty bad.

This is the kind of thing that support could help with. Perhaps email "techsupp@ansys.com", but they would also want a customer number.

Good luck with this and I hope you post what you learn.

My solution was to meticulously capture all of the maneuvering/experimenting with the geometry in ICEM's tree using a series of replay command recordings (selecting the box "all commands" in the replay control window, which captures everything, even inadvertent flyovers of the mouse!). I then concatenated all of my attempts into a single script. Unfortunately it won't run in batch mode, so the GUI opens and closes. The result was the desired black lines on white background postscript, without the surface faceting, blocking, etc. This jpeg doesn't really do justice.

I attach here the entirety of the commands which I used to switch off the various views and visibilities. Trimming down this monster code segment to the essential is an exercise which I leave to the reader :-)
