However, it is not\nstringently following conventional multi-grid methods as we simply want\na reasonable guess for the Poisson solution.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fzerothi%2Fmultigrid","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fzerothi%2Fmultigrid","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fzerothi%2Fmultigrid/lists"}
