Hello, I am simulating a 3D FSI model of an aortic valve inside a fluid domain. The valve consist of 3 leaflets which deform symmetricaly but i am simulating only the one of them. Since normally the leaflets are very close to each other, the deformation of the one leaflet i am modeling has to be so such the leaflet does not penetrate the other two hypothetical adjacent leaflets. How can i make this restriction? In other words i dont want the leaflet to deform in the direction where the other hypothetical leaflets are, but start from its initial position demorming to the outward direction radially. Can anyone suggest me an option? I attached some photos of my model to be helpful. Thankyou
