About launch pad installation for totally clean Ubuntu

Postby Estiivan » 05 Dec 2016, 13:49

Hello all,

Thanx for annier and rest. After facing troubles without a known cause (for me), I decided to install Ubuntu 16.04 LTS anew to my computer in order for sure to be free from previous Elmer installation tries. I followed this time launchpad instructions given in https://www.csc.fi/web/elmer/binaries

$ sudo apt-add-repository ppa:elmer-csc-ubuntu/elmer-csc-ppa
$ sudo apt-get update
$ sudo apt-get install elmerfem-csc

And at least ElmerGUI starts without problems. However, there are no Elmer folders to be found. If I search with locate for elmer* nothing is found. Where does the launchpad put Elmer?

I would like to do tutorial examples given in ftp://nic.funet.fi/index/elmer/doc/ElmerTutorials.pdf but I think files related to examples (like geoslab.grd) were not installed by launchpad. Or? Can I still get them?

With regards and happy ID for all,
Estiivan

Hi Estiivan,
1. Launchpad will install the Elmer libraries into different places of the computer system such as /usr/local/share or something like that as root folders. So, you can perform every command of Elmers without difficulty as it is distributed along the related directories . So, you can search in the folders /usr/... of your computer system. This is useful especially for ElmerGUI xml libraries for which you need to transfer edf extra to edf files as suggested before and getting the samples installed with ElmerGUI. Any persons installing Elmer via launchpad can guide you with where these things are installed.

2. Yes, you can get these examples in the installed location of ElmerGUI samples (/usr/local/share/.. or /usr/share/... or any other - I could not remember the exact location as i had done it quite a long while ago and now in my ubuntu system I have the cmake based installation.). For your ease, you can copy these samples to your home directory. Or, you can download Elmer latest version from https://github.com/ElmerCSC/elmerfem into your home directory in the folder or directory name myfolder. The tests and samples from there can be run (without installation as u have already installed Elmer via other way) with ElmerSolver and ElmerGUI command .
I. Type ElmerGUI command in terminal -->> Open /HOME/myfolder/elmerfem/ElmerGUI/samples/grd/geoslab.grd and run in accordance to the tutorial.
II. Open /HOME/myfolder/elmerfem/fem/tests/anytest and run in accordance to the nonGUI tutorial -->> Type ElmerSolver command in terminal


Summary,
1. Installation via launchpad will allow you to open Elmer libraries by typing command in to the terminal. It will disperse the installed libraries into your root directories in accordance to the path suitability for access.

2. For learning how to run tutorials, you can download Elmer from github and you can run the examples of this downloaded Elmer in uninstalled form by using the Elmer commands from your installed libraries. After a while, you will know by yourself where these all libraries of Elmer are installed in the root system of Ubuntu.


Yours Sincerely,
Anil Kunwar

Thanx Annier,

samples seemed to be under /usr/share/ElmerGUI/samples/grd. So I was quite positive that now everything would work but still first example of tutorial fails when I hit solver button:

ELMER SOLVER (v 8.2) STARTED AT: 2016/12/05 16:07:24

Sigh... What is it now? ... I tried to browse forum but did not find any definite answer how to get rid of this problem.

I have in .bashrc three lines as instructed:

export ELMER_HOME=$HOME/elmer/install/
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ELMER_HOME/lib
export PATH=$PATH:$ELMER_HOME/bin

I am using geoslab.grd file from /usr/share/ElmerGUI/samples/grd. Model summary:

Clearly, the elmer installation directory is not Home when you install elmer via launchpad.
So, in your bashfile:
#export ELMER_HOME=$HOME/elmer/install/
#export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ELMER_HOME/lib
#export PATH=$PATH:$ELMER_HOME/bin

But I think the above error is not related to this.

This is related to the mesh path or mesh definition or pointing to the mesh or mesh initialization which you have not completed before you run ElmerSolver in GUI.

Hello Annier,

Seems to work now (at least solver starts and does something). I uncommented export lines .bashrc

#export ELMER_HOME=$HOME/elmer/install/
#export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ELMER_HOME/lib
#export PATH=$PATH:$ELMER_HOME/bin

and now ElmerGUI seems to work. I added those export lines after first run crashed and thought reason was that I had forgotten to add them to .bashrc. But I guess problem was that I had not saved the project before hitting solver button.

Many thanx!
