LPP released - parallel VTK converter based on pizza

Dear all,

I have installed OpenFoam 2.1, LIGGGHTS 1.5, CFDEM 2.3.0 succesfully.

At the meantime, I am tring to install LPP.

By the following comand in terminal window bashrc was opened : gedit /home/sderakhshani/.bashrc &

Then I added these lines to bashrc:

CFDEM_lppPath=/home/sderakhshani/mylpp
alias lpp="python $CFDEM_lppPath/src/lpp.py"
alias pizza="python $CFDEM_lppPath/src/pizza.py"

Question 1:
I can see also these lines in the bashrc :
#- pizza
alias pizza="python -i $HOME/LIGGGHTS/PIZZA/pizza_17Aug10/src/pizza.py"

Should I comment this line?

Question 2:
After changing bashrc, should I activate new env vars by ". ~/.bashrc" or not ?

Question 3:
In the new terminal I checked aliases with these commands:

which pizza
which lpp
which liggghts

And saw these results:
sderakhshani@ubuntu:~$ which pizza
sderakhshani@ubuntu:~$ which lpp
sderakhshani@ubuntu:~$ which liggghts
/usr/bin/liggghts
sderakhshani@ubuntu:~$

I think here is problem regarding to pizza & LPP !!!

I do appreciate to help me.

Thanks in advance.

Cheers,
Ebrahim
