Elmer Discussion Forum

I wanted to learn more about Elmer and attempted an installation on my MacBook Pro running OS X 10.11.3. The installation went smoothly with several warning message but received some ctest errors as given below. Given the names of the failed tests I wonder if there is some commonality that one could point to as the culprit. I would appreciate comments to help me obtain an failure free installation.

96% tests passed, 16 tests failed out of 361

Errors while running CTest

Hi

Almost all seem to involve complex valued linear systems. Two of the cases have a senstive norm which seem to cause problems in some other platforms as well.

You could print out the output of "linearsolver_cmplx".

Peter,
Thanks for the feedback. As I am new to Elmer I will first need to learn how to "print out the output of linearsolver_cmplx". But your suggestion seems well founded.

Hi!

In my experience the OS X's Accelerate framework does not work with elmer. Instead I'd suggest using OpenBLAS (www.openblas.net) or reference blas/lapack for blas and lapack library. OpenBLAS installed with homebrew should work so long as you provide cmake with variables "BLAS_LIBRARIES" and "LAPACK_LIBRARIES" that point to the correct files.

Cheers,
Juhani

Hi Juhani,
Thank you for your thoughtful suggestion. I'll give this a try.

Hi there. This procedure seemed to install elmer jsut fine on my mac (hopefully I did not just glimpsed over errors):

Here's a series of videos on how to install Elmer on macOS.

The first one shows how to use Homebrew's gcc compiler and the second one how to install a full fledge version of Elmer with MPI and ElmeGUI
