Multilateral well simulation

[arm]

Hi everybody
I have simulation model with multilateral wells. In schedule part of data file the wells defined as below.

as you can see multilateral well cuts the gird several times. Is it logic to have well connection like this. The well is openhole.

your grid resolution may be too big. you may try local refined grid around the laterals.
