Hi everyone. 

I am trying to do a simulation on a battery pack As I finished all my physical setup in fluent and try to initialize it, it gives me "Error floating point exception Error Object: #f" error. As I checked in some other threads it might be due to the mesh, i made it refine and I had like 13 million faces which it said couldn't be solved. So, I am not sure this is happening for rough mesh or due to some other reason?

Anyone can suggest me to sort this problem? Thanks

Please add some more details? Are you working with Student license? The error message might have several reasons.

I think I got a little idea that I might be able to solve it. Can you please let me know how can I hide those faces so I can select parts to name which can be used later on in meshing and fluent solver? When I select and try to hide them it hide the whole thing? I was watching a video in ANSYS version 19 in which option of faces comes and you can simply hide them from there?

I am using the actual version and there is an option to hide faces. RMB then face then hide face

This is what I am getting. I am using ANSYS version 18.2. I even checked in help but no luck

You need to update.

That's a great suggestion but unfortunately with the student version I can only have 512K cells/nodes so I am not sure once I uninstall this the new version is going to help me to achieve what I am aiming for. Is there no other way to hide a face in ANSYS version 18.2?

use ctrl to select more than one face.
