full screen ubuntu in an oracle vm

Day 1: Sort it.  A search, a line in the terminal, done.

Day 2:  New VM.  A search.  NO JOY.

Day 3:  New searches.  I find it again.

How can it be so damn hard?!

Anyway, in the VM: 

sudo apt-get install virtualbox-guest-dkms virtualbox-guest-utils virtualbox-guest-x11

Thank you. No big deal. No freaking mouse clicks. No idiocy.

Earth provides enough to satisfy every man's need, but not every man's greed.  Mohandas Gandhi.

If slaughterhouses had glass walls, everyone would be a vegetarian.  Paul McCartney.

Flesh eating is unprovoked murder.  Benjamin Franklin.

A man can live and be healthy without killing animals for food; therefore, if he eats meat, he participates in taking animal life merely for the sake of his appetite.  And to act so is immoral.  Leo Tolstoy.

My body will not be a tomb for other creatures.  Leonardo Da Vinci.

However scrupulously the slaughterhouse is concealed in the graceful distance of miles, there is complicity.  Ralph Waldo Emerson.

There is no fundamental difference between man and animals in the their ability to feel pleasure and pain, happiness, and misery.  Charles Darwin.

Nothing will benefit human health and increase the chances of survival of life on earth as much as the evolution to a vegetarian diet.  Albert Einstein.

Need a quote incriminating all those who argue against it, too.....  Idiots.  Assholes.

OpenFOAM: negative volumes on good looking mesh. Empty sample results.

blockMesh defined with incorrect topology:


Far nodes:


4   5
0   1


Near nodes:

7  6
3  2


I used topo 0 1 2 3 4 5 6 7 and the mesh created okay, with warnings during blockMesh:

 Creating block mesh topology
--> FOAM Warning :
    From function cellModel::mag(const labelList&, const pointField&)
    in file meshes/meshShapes/cellModel/cellModel.C at line 128
    zero or negative pyramid volume: -1.66667e-05 for face 0



(ignored, obviously).  On sample, tets could not be created.  checkMesh showed all cells to be stretched and negative volume; paraFoam showed them as okay.

Anyway, using the (correct) topo  : 3 2 1 0 7 6 5 4

fixed all this.

From the terminal running paraFoam:

--> FOAM FATAL IO ERROR:
Please supply the offsetMode as one of

(

This was from using Paraview 3.12.0 with openFoam 2.3.

Installing updated foam and paraview (well, parafoam) fixed this.  The same directory now works fine.

openFoam wisdom

Specify velocity AND pressure at a boundary and expect continuity errors.  Set zero gradient (not non-zero gradient) and velocity.

------------------

Calculate initial k and epsilon values with this script:

#!/bin/sh 
echo ' ===========================================' 
echo ' give me Uref, Turbulent Intensity and L' 
echo ' I will give you TKE and epsilon for inlet' 
echo ' ===========================================' 
### 
Uref=$1 
ti=$2 
L=$3 
tke=$(echo "scale=4;1.5 *($Uref * $ti)^2"|bc -l ) 
epsilon=$(echo "scale=4;0.09^(3/4)*$tke^(3/2)/$L"|bc -l) 
echo 'tke =' $tke 
echo 'eps =' $epsilon
