Hi Elan,Elanid wrote: I have the 32bit version of Ubuntu 14.04, the gcc and the gfortran versions are 4.8.2. I've tried installing the new version of elmer, from git, and used cmake-gui to have elmer without any bells and whistles, just with the MPI. The configuration and generation did not display any errors or warnings, so I used make and make install.
My Ubuntu 14.04 bit is 64 bit.
The difference in test results might be due to the bit size. Nowadays, most of the softwares are built for 64 bits.
However, if configuration and generation (build), make and make install proceeded successfully, Elmer has been successfully installed in your machine. the ctest (test) might have some components which might be sensitive to the bit size and showed some errors.
can you get the ElmerSolver result for the Lid Cavity test as mentioned in the first post?
Also, as mentioned by Peter, you can try to check the working of ElmerSolver through some examples. If ElmerSolver works, then your Elmer is installed successfully for numerical calculation.
The test is related with the integration and interaction of every components during installation via Cmake.
