Thank you so much for the reply. I've deactivated "auto mass scaling" and put "section" with hourglass coefficient 0.005. Tried to hex element but it didn't work but I've got better mesh after I had simplified the geometry. With "section", I've selected ALE and started to run. I'll let you know if it runs without error. Also, I'm trying to solve the analysis with FSI. Thank you so much again for your advice.
