Thanks Barry for quick reply. After I type ./ex5 -help | grep view, it comes out a list of options related to _view, all of which have the tag <FALSE>, what does this mean?<br>

<div>The <FALSE> is the current value. They are all false because you have not turned them on. IF you are using the release version,</div>
<div>the viewing option is -da_view. The -dm_view is the new version which we are about to release.</div>

Run as./ex5 -help | grep view to see the possibilities. It depends on PETSc version number. When using the graphics want you generally want a -draw_pause -1 to stop that program at the graphic otherwise it pops up and disappears immediately.<br>

> Hello, I'm new to PETSc. I'm reading a tutorial slide given in Imperial College from this site: Slides. In slide page 28, there is description of viewing the DA. I'm testing from my MAC the same commands listed on that page, for example, ex5 -dm_view, nothing
interesting happen except the Number of Newton iterations is outputted. I'm expecting that the PETSc numbering would show up as a graphic window or something. Can anyone tell me what's missing here? Thank you! ( Hui )<br>
