Unwanted Constraint?

Hi! I am new to COMSOL and I am having an issue with my model's behaviour that I could use some help with. I have attached a screenshot of my model and circled the area of interest. My goal is to achieve a bowl-like figure as a result of stress, but due to an unknown constraint it seems the leftmost point is unable to move, which is unrealistic. I have included the toolbar in the screenshot to show what I currently have implimented, I believe the issues lies in the Rigid Motion Suppression Domain. If anyone has any advice/knows what might be causing this behaviour please let me know!

Hello Emily,
See this old thread. If you want to control the resulting shape, you need to specify the constraints yourself, as opposed to relying on rigid motion suppression.
Best,
Jeff
