Dear OpenFOAM users,

I will try to be as detailed as possible.

I have OpenFOAM 5.x installed and running fine. I tried installing foam-extend-3.1 by downloading and running binary:
$ sudo dpkg -i foam-extend-3.1_amd64.deb

Before running dpkg, I followed Ubuntu prep work:
sudo apt-get install git-core build-essential binutils-dev cmake flex bison zlib1g-dev qt4-dev-tools libqt4-dev libncurses5-dev libiberty-dev libxt-dev rpm mercurial graphviz

======= FYI +++=====
Linux core on Win10:
lsb_release -a

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.5 LTS
Release: 14.04
Codename: trusty

After trying to install binary with dpkg, the shell returns error:

Selecting previously unselected package foam-extend-3.1.
(Reading database ... 117165 files and directories currently installed.)
Preparing to unpack foam-extend-3.1_amd64.deb ...
Unpacking foam-extend-3.1 (3.1-1) ...
dpkg: dependency problems prevent configuration of foam-extend-3.1:

foam-extend-3.1 depends on hwloc; however:
Package hwloc is not installed.

dpkg: error processing package foam-extend-3.1 (--install):

Errors were encountered while processing:

Even though there was error, foam-extend-3.1 has been installed into

OpenFOAM 5x is installed into /opt
So, the current content of /opt directory is

username:/opt$ ls
foam openfoam5 paraviewopenfoam54

I tested fe31 works fine and calculates the icoFoam case. However, paraview does not work. Then, I reloaded the environment with of5x and ran parafoam. It worked (ParaView 5.4.0 64-bit Legacy Rendering Backend).

My questions are:

1) Should I worry about installing paraview, python-paraview, hwloc ?
I assume OpenFOAM 5.x. has this packages already.

2) Do I need to / How to fix dependencies error described above (namely, paraview, python-paraview, hwloc) ?

3) (Optional) Can someone briefly clarify why such issue arise in the .deb ?

4) Is there a binary for foam-extend-4.0 on Ubuntu 14.04 ? or I need to build it from source ?

5) What is the elegant way to have parafoam work when fe31 environment is loaded? Could someone please point me in the right direction ?

6) Do you think fe31 has been installed fully ?

Thank you in advance,

Quick answers:
  1. If foam-extend is working and if OpenFOAM 5 is working with ParaView, then there is no reason for concern, but to keep things somewhat simple, you should then have 2 terminals open on the same folder: one with foam-extend and another with OpenFOAM, so that you can use paraFoam on the OpenFOAM terminal whenever you need to.
  2. You can install the missing packages by running:
    sudo apt-get install paraview python-paraview hwloc
  3. See #2.
  4. AFAIK, you must build from source code.
  5. There was a thread where I wrote about this... OK, see the following threads:
  6. I don't know what are the final configuration steps that foam-extend 3.1 Deb package has, but if you want it to properly finish configuring, you need to first install the packages in #2 and then re-install the foam-extend 3.1 Deb package.
