Hello I would like to project an arbitrary domain defined by piecewise functions in inequalities into a uniform quadrangular mesh. I will basically loop over the elements over the uniform mesh, calculate its centroid and check if it is inside the domain by satisfying the multiple inequalities given by the piecewise functions that define the domain. For instance, if such domain is a rectangle of length “L”, width “d”, with its bottom left vertex anchored to the (0,0) point and its longest side parallel to the X axis, the inequalities would be something like:
x > 0 && x < L && y > 0 && y < d I wonder if there are functions within libMesh that can make my life easier and if this has done before. I think I could use a ParsedFunction for this simple example, but I want more complicated geometries. I would like that rectangle to have a circular notch on the top side, for instance.
