I want to use convolution in CF，but I cannot find function that computing convolution in documentation
depends on …
How do you want to realize the convolution operators on unstructured grids on bounded domains ? do you have references ?
Hi Joachim,
In terms of numerical implementation, I have not found any reference materials. Currently, I am reading a paper on shape optimization. In the paper, a Gaussian convolution kernel is used to perform a convolution operation on the characteristic function of a set (∫𝐺𝑡(𝑥−𝑦)𝑋(𝑦)𝑑𝑦). I would like to inquire if there is a built-in convolution function in ngsolve. If not, I am considering writing one myself.
Best,
Yuanda Ye
