I made the changes as you said and the simulation is running. But, with 12 cores itself, it took 14 hrs to calculate just 3 seconds (still ansys need to calculate creep for 597 seconds), and it has generated almost 40 GB of data for those 3 seconds. I am not sure why it is like that. is there anything i am doing wrong. I have following settings.
I am using 'direct solver'.
weak springs 'on'
creep limit ratio is ' 100' . (any value below 100 is not making the simulation to run)
Initial time step : 1s
Min time step : 1e-4s (simulation is not running for )
Max time step: 40s
Environment temperature : 280c
Will be waiting for your reply.
