in 2D fsi mode , i cant define "contact pair" ?

Please login with a confirmed email address before reporting spam

Dear Dr. Ivar,

I am trying to simulate natural heart valve in 2D fsi mode. when leaflets contact an error occurred.

Repeated error test failures. May have reached a singularity.
Time : 0.002592892726514386
Last time step is not converged.

When I define “contact pair” in definition and add “contact 1” in fsi node , I get error:

Failed to find consistent initial values.
Last time step is not converged.

How can I use contact pair? Or is there another way to modeling this example?

Please help me

Thank you so much!
