This is more a note to the universe than a question.

I have recently got a new machine with Ubuntu 20.04 on it, and I installed a couple of OpenFOAM versions on it.
For some stuff I needed an OpenFOAM-6 installation, hence I compiled one from source code.
With OpenFOAM itself, I encountered no problems, however, ParaView had some issues.


It turned out, that I needed to apply the changes described in this post, which are some changes to support Qt-5.11. On my machine (pretty vanilla Ubuntu 20.04 there is Qt 5.12.8).

Furthermore, I needed to install the qtxmlpatterns5-dev-tools package, since compiling ParaView stopped with an error.

Another change that was necessary, was this one.

Hi Gerhard,
I'm curious about why you need to compile paraview from source at all. I've generally found that a precompiled paraview binary v5.6.3 or newer works quite well. The only thing might be if you need the catalyst insitu as well, in which case you can't avoid it.

I think habit is the correct answer. I have always installed OpenFOAM from source, hence this is what I do by default.

Hi Gerhard,
I'm trying to install OpenFOAM 6 on ubuntu 20.04, but It's the first time I compile OpenFOAM from suorce code, and I'm not very expert.
Is possible to compile OpenFOAM without compile Paraview?

This would be my standard answer regarding paraview :

Of course, if you have Ubuntu 20.04, I would probably go for a precompiled binary:

This use the repository from openfoam.com, I need the version of the openfoam foundation, do you know if is possible install the binary of openfoam 6 in ubuntu focal?

I'ved found the binary, and resolved my problem.
Mark thankyou for your help

I'm trying to make PV work with OF6 on Ubuntu 20.04 LTS. After some troubles as described in this thread, I decided to go as you (sort of) suggest with the PV package available from the package manager (5.7.0), but what I've found is that PV fails to launch if I source the OF6 environment.
The error it gives is related to OpenMPI:

--------------------------------------------------------------------------
It looks like opal_init failed for some reason; your parallel process is
likely to abort.  There are many reasons that a parallel process can
fail during opal_init; some of which are due to configuration or
environment problems.  This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):

  opal_shmem_base_select failed
  --> Returned value -1 instead of OPAL_SUCCESS
--------------------------------------------------------------------------
--------------------------------------------------------------------------
It looks like orte_init failed for some reason; your parallel process is
likely to abort.  There are many reasons that a parallel process can
fail during orte_init; some of which are due to configuration or

here's some additional information (which may only be relevant to an

  opal_init failed
  --> Returned value Error (-1) instead of ORTE_SUCCESS

additional information (which may only be relevant to an Open MPI

  ompi_mpi_init: ompi_rte_init failed

--------------------------------------------------------------------------
*** An error occurred in MPI_Init
*** on a NULL communicator
*** MPI_ERRORS_ARE_FATAL (processes in this communicator will now abort,
***    and potentially your MPI job)

I believe it probably depends on the fact that I compiled OF6 against the usual ThirdParty OpenMPI 2.1.1 (not being able to compile against the system OpenMPI 4.0.3).

So, just to provide a broader view, it seems that integrating a pre-compiled PV in a OF6 environment is not that straightforward. Of course I can launch PV in a separate terminal, but it's far from ideal so I think I'll try to give the shipped PV another try.
