Qtvlm stops simulation stating aground. When depth is 25 mts?

Hi, I have run many simulations and Qtvlm stops simulation stating aground. When depth is 25 mtrs?

The boats depth is not 25 mtrs?

Hi,
Which version are you using? The one released today (5.10.9) has many changes concerning depth and simulation mode.

What are the values you have set in Charts->Rasters and Vectors for Shallow Contour, Safety Contour, etc ?

I have used new version today and also went back to older version.

I changed the depths to around 2 5 and 8 for deep

The rule is that whatever has a depth equals or less than shallow contour will be an obstacle and therefore will make simulation to run aground, and whatever is between shallow and safety will only be a danger and will trigger an alarm. Whatever can be rock, wreck, sounding, obstruction, depth area and depth contour.
