There are two ways to output the mpio format from Ansa, with or without GUI.
|
|
|
|
Ansa2mpio is a python script which allows to write meshes from Ansa to the binary mpiio Alya format. There are two ways to output the grids: with or without GUI.

This option is much more tedious because every time you start a session in Ansa you have to reload it. That is why I discourage it. In any case, it is explained what to do if you want to use this route.
