Hi,

I am performing on sloshing inside a deformable fuel tank.

Do I have to define an interface between water and tank ?  If yes, Do you please suggest card image for step ' create > set ' ?

When I would create 'contact' for water and tank, I should select card Image is ' Type 18' or ' Type 1' ? and there is any difference in final output ?

Thanks.

    Hi Duong,

    You have to define an interface between the fluid and the tank. Please try with creating Type 7 interface (Select type as Type 7). Type 7 is a multipurpose interface.

    Hi Duong,

    IOFlags are input-output flags. If Ipri is set to 5, part mass, inertia, nodal masses, initial velocities,interfaces, node coordinates,  deactivated elements from rigid bodies..etc details output will be given. Similarly OUTyy is also for the output format.
