Fluid simulation: Why does water come out of domain?

I created the character M and then I converted it into mesh. This is the domain of the fluid simulation. I created a sphere and placed it inside the M character and it is the inflow object. The water leakes as if the M character has a hole :smile: Would you tell me how to solve this? I tried to make it an obstacle but it didn’t work form me too.

You got the idea wrong for the domain, Domain is the space that lets the fluid run the simulation. so create a box around M and make it the domain

Increase the water flow by adding velocity in “inflow”

And make the M an obstacle and choose Volume initialization to shell.

Thank you so much for this great answer. It’s short and contains a lot of info :wink:
