Reply To: Ansys mechanical slow on startup

This seems similar to a known bug in 2024R1. 
There is a Service Pack for 2024R1 (SP3) that may help, although I would use 2024R2. 
Note: Even with the 2024R1 (SP3) / 2024R2, it will take time to open the Mechancial the first time. 
Allow Mechanical to open the analysis, then make a small change (rename a branch, add a coordinate system etc) then Save, Close and reopen.
Resuming thereafter should then be normal.
