I had gcc and gfortran installed already.<br class="">
<br class="" /><br class="">
I have installed open-mpi<br class="">
<br class="" /><br class="">
It still does not work.<br class="">
<br class="" /><br class="">
I have followed the instructions, however I had to change the second line dragging the tar file from the desktop to the terminal otherwise I would have got the following error:<br class="">
tar: Error opening archive: Failed to open ‘Nek5000_X.Y.tar.gz'<br class="">
<br class="" /><br class="">
Is the software supposed to open after the line run?<br class="">
<br class="" /><br class="">
Kind regards <br class="">

No I haven't installed the software below but I will do. I have tried to install it using the terminal but unsuccessfully, I do not have a great knowledge of it, I have tried with Homebrew.On-line I found a sequence of instructions about installation on ubuntu.<br class="">
Something like that would be really useful. <br class="" /><br class="">
Thank you for your replies.<br class="" /><br class="">
