Hi!
I have a similar problem, with error:

Error: CAR: invalid argument [1]: wrong type [not a pair]
Error Object:
It occur when i open Fluent, after the creation of volume mesh and have no idea how to fix the problem.

The CAR errors are typically associated with a missing setting that Fluent is expecting. If it's a mesh that triggers the problem check the Named Selections in the meshing tool. Where did the mesh come from?

Hi Rob! Thank you in advance for your answer.

So the problem born because in my office i used Fluent into my workstation that has 4 cores and i use Ansys 2020 R1.
When i export the mesh and send it towards another Pc that has more performance than mine (32 cores and has the same Ansys 2020 R1) the problem occur when i import mesh and go to setup of simulation.
I've tried also to transfer all the case study, but when i go to open only fluent the problem occur.

More cores won't cause this, it's something in the set up that's not correct. What happens when you initialise & try and run the model?

[Zordiak]

After some attempts to load and settings it seems to have recognized the mesh and fixed the problem and i can lunch the simulations.
However when the error occurred the toolbar was not work, i had to exit and try again because the toolbar didin't work

That sounds more like an interface problem so could be graphics related. Glad to hear it's working as I suspect we'll struggle to diagnose on here.

Thank you very much for your time Rob!
Have a nice day!
