* katsmeow-afk is looking for opinions: what does the prefix "epi" mean in here?00:18
willPow3rtop, outermost00:19
willPow3ror before00:19
katsmeow-afkas in epistemology or epidermis, and it is the real prefix (if any) in epistemology ?00:20
katsmeow-afknot "root of branching structure" ?00:20
kanzuresounds right to me00:20
kanzurefor epistemology, I mean.00:20
* katsmeow-afk hmms over it a bit00:21
kanzurehm, 60 MB results file for 2 seconds of a simulation00:22
kanzureyeah, I'm going to need the visualization lab for this00:22
* kanzure cackles00:22
gene_really?00:24
gene_or can your super box do it?00:25
kanzuresuper box froze trying to do it00:25
kanzurebut it worked for a while, and I didn't actually see anything that looked like useful results00:25
gene_reallly?00:25
kanzureso I'm going to try running a reduced model just to make sure it's doing its thing00:25
kanzurelike a 20-point model or something :p00:25
kanzurehuh, but it runs on the laptop under ElmerPost00:36
kanzurejust no data was generated. hrm.00:36
kanzureok, will have to run the reduced model00:36
kanzureis it ok if the spiral suddenly becomes approximated by a square? 00:36
gene_is a spiral a square?00:37
gene_if it is then yes00:38
kanzureno?00:38
kanzurehrm.00:38
gene_is just the spiral channel being simulated?00:39
kanzuredo you know how this works?00:40
gene_or are you simulating the block the spiral is in00:40
kanzurewell, the mesher includes the block, but the simulation doesn't bother with points in the model that nothing is happening at00:40
gene_are you sure?00:40
kanzureno00:40
kanzureit certainly takes up memory, if that's what you're wondering00:41
kanzureanyway, just generated the 130-coordinate version of the spiral (hah)00:41
gene_then lets find a way to reduce it00:41
kanzurethis is it. no way to make this smaller.00:41
* kanzure tries running it now00:41
* kanzure runs ElmerSolver again00:41
kanzureyep, much faster00:42
kanzureamazing00:42
gene_cool00:42
gene_visuallize it00:43
kanzurehrm, elmergui isn't showing it (which is the important part- it's through elmer that we can set the boundaries and initial conditions)00:43
kanzuremaybe I should run it through gmsh again just to be sure00:43
kanzuresegmentation fault. blah. I like how it doesn't say what's wrong.00:46
gene_wait a minute00:47
gene_you can simulate the fluid flow in pictures00:48
kanzureElmerFront still works though. just don't know how to select the right locations with a mouse.00:48
kanzureyes00:48
kanzurebut I have the model working now00:48
gene_I need to send you some pictures00:48
kanzureI recompiled gmsh with OpenCASCADE support00:48
kanzureso that it can open up the IGES/STEP files, and that's what I'm generating the mesh from00:48
kanzureand once the mesh is generated, it's passed to ElmerGrid, and then from there I can open it up with ElmerFront (and theoretically ElmerGUI, but that doesn't seem to be the case)00:48
kanzureyesterday I figured out how to select "inlets" (boundaries) with ElmerFront in some obscure menu, but when I checked back today, it no longer exists there00:49
gene_sent00:50
kanzureaha, found it00:53
kanzurebitches.00:53
kanzuregene_: this is what I mean by boundaries: http://heybryan.org/bioreactor/membraneless_filtration/2009-03-30_boundaries.png00:57
gene_is that an outlet?00:57
kanzureyes00:57
gene_ummmm...00:58
kanzuresshh, I was just randomly clicking00:58
gene_I don't like the way that you are still simulating much of the block00:58
gene_oh and how do i boot into ubuntu?00:58
kanzuredid you install it?00:58
gene_yeah00:58
kanzurehave you rebooted since then?00:58
gene_yeah00:59
kanzurewere you looking at the screen the entire time?00:59
gene_no00:59
kanzurewell there's your problem :)00:59
gene_I'm going to restart00:59
kanzureit's an option menu when you're booting up00:59

kanzurecan't use empty string as operand of "!" why not? the problemed line is "if { ![Boundary::readDiscretationData] }"01:10
kanzurewhat's so wrong about asking about !"" ?01:10
kanzurethat should evaluate to true01:10

gene_ok kanzure01:12
gene_I get a command line01:12
gene_initramfs or something01:12
gene_how do I get to the cool GUI?01:13
fennyou broke it!01:17
kanzuredid you try pressing ALT+F7 ?01:21
gene_no01:21
gene_what does that do?01:21
kanzureinitramfs is usually where it is doing the mount process01:21
kanzuredid you wait?01:21
kanzureALT+F7 switches to tty7 which is usually reserved for "cool GUI stuff"01:21
gene_it said loading01:21
kanzureso obviously you had to turn it off01:21
ybitjust wondering, what's with the windows styling? is it a win machine?01:22
gene_there was a flashing command line 01:22
gene_it is01:22
kanzureybit: what's with the what?01:22
gene_a win machine01:22
ybitfrom your linked image above01:22
kanzureKDE01:22
ybitah, good man01:22
kanzureheh, clicking "cancel" on the boundaries window (which was producing that error) and then checking back on the same menu shows that its error wasn't actually an error and it was just complaining to be an attention whore.01:23
kanzureoh wells.01:23
gene_ok so try alt+f7 then01:26

* kanzure qmake&makes elmergui01:36
fennlooks like it01:39
fennit's ctrl-alt-f7 btw01:39
kanzureonly when you're in an x session01:40
kanzurein which case you're already there01:40
kanzureelmergui failed "with too recent version of Qt Designer (4.0 vs 3.3.8b)"01:41
kanzureyou've got to be kidding me. Qt Designer? sigh01:42
kanzurewell, at least I can apt-get install qt3-designer01:42
kanzureapt-get remove qt4-designer worked, but then it still complains that I have 4.0.01:43
kanzuremaybe I'll make clean.01:44

gene_but I forgot the username I gave it when I installed it01:45
gene_I fail it01:45
fenni'm disappointed in you gene_ 01:47
ybit:P01:47
ybityou are trying though01:47
gene_I guess I'll just brute force it with all possible passwords I could have typed01:48
fennubuntu is probably the easiest thing to install ever01:48
ybithehe01:48
gene_yeah01:48
gene_it was easy to install01:48
kanzureit should still have the user name in wubi01:48
gene_where is wubi?01:49
kanzuredidn't you use wubi?01:49
gene_yes01:49
kanzureI'm confused.01:49
gene_I used wubi01:50
gene_what sort of file should I look for?01:50
kanzurethen go use it again01:50
kanzurejust don't install ubuntu01:50
kanzureit will still have the username written down in one of the fields01:51
gene_ok01:51
fennoh i thought he already installed ubuntu01:51
kanzureI think he did01:51
kanzurehe forgot the username01:51
kanzureit's specified in the wubi gui wizard thing01:51
kanzureI remember this because I had a corrupt ubuntu install (I know, gay) on a recent windows box01:51
gene_wubi wants to uninstall ubuntu01:52
gene_I installed ubuntu01:52
kanzurehrm.01:52
kanzurewell, don't do that01:52
kanzurejust remember the username and password?01:52
