Hi, Thanks to you all for the feedback. The ANS paper and the plans for sophisticated quadrature are great. One further point of clarification: I am new to XFEM, but have been interested in level sets for a while, in particular in the distributed parallel context. Do I understand correctly

Hello, What's a good way to integrate a quantity in the vertical direction? For example, how do I find the weight of water above a point (assuming variable density, so that the integration is necessary)? In a structured regular mesh, I would fix the x and y coordinates of the grid and iterate

Dear dealii community, I am interested in solving a nonlinear problem with Newton's method. I would describe it as a heat equation with a nonlinear diffusion coefficient, thus building on step-15, 25 and 26. I've found step-15, step-25 and step-57 very helpful for understanding how to set up

Hi Simone, Were you able to successfully compile one of the "step" programs? https://www.dealii.org/developer/doxygen/deal.II/step_1.html does a nice job describing the approach using cmake. Modifying the CMakeLists.txt of one of the step tutorials for your own user code is common. Best,

Hi Jane, Hi Wolfgang, The case that I was looking at was to solve for a velocity field variable. As Wolfgang nicely describes, the power of the idea is to take a line integral equation and by operating on the equality, to formulate it as a PDE. So, if you are interested in a displacement
