Unknown Error Occurred During Solution
I am running a static structural simulation of an animal's upper airway. I am applying a pressure on the airway walls and I am checking at which pressure the walls come into contact using the Contact Tool (Gap) in the solution. For more details about the model please refer to the discussion below.
I have added more bodies to the geometry shown in the previous discussion and I need to increase the number of substeps to 1000 because I need 4 digits of precision to determine an accurate pressure value. For a low number of substeps (15) the model is solving but when I increase the number of substeps I am getting an error ("Unknown Error has occurred").
I've attached the content of the Solver Output.
Could you please help me understand the reason behind this error and if it can be solved by using a different, more powerful computer.
Thank you for your help.
