I installed Elmer on the virtual machine following the steps of this document.
https://www.nic.funet.fi/index/elmer/do ... dElmer.pdf
Afterwards I tried to conduct the steps described in the video of Elmer Command-Line Workflow (see the link below).

Unfortunately, I fail to run the simulation described at min 4.58.
I get the Solver output depicted below.
