defining a crack front in the "From Geometry" or "Symmetric" surface definition

Hello,
I want to analyze the crack growth rate in a steel machine part. When adding the crack node in COMSOL, you must define the crack surface as either "Slit" "From Geometry" or "Symmetric".
Since my geometry doesn’t allow me to use a symmetric feature where the crack is simulated, I need to use either the "From Geometry" or "Symmetric" surface definition. In both of these modes, I’m unable to define a crack front. As a result, I also can’t add a crack front in the Virtual Crack Extension node.
Does anyone know how to define a crack front using the "From Geometry" or "Symmetric" crack definitions?
I am only able to work in the Solid Mechanics Module, as my university’s version does not include the Fatigue Module.

I guess you mean "From Geometry" or "Slit".
I think you would have to provide an example where you cannot define the crack front. It should work.
