Checking concave faces

Hi, I I have been wondering if there is a way to check this kind of problem in meshes. I use MeshLint to check a lot of problems but this kind of problem is missing in this addon. In my work I have to be very carefull with this and checking it manually could take me quite some time. Is it posible to check it?

Not sure what you mean by concave faces but if you want to show non planar faces you can use the Mesh Analysis options in the properties panel (shortcut N) in edit mode, set to’Distortion’.

Concave faces are quads that have this kind of shape.
I already checked with mesh analysis and none of the options seems to detect this error.
