"Put your background field on a 3 grid that covers your surface" My background field is a 2-dimension field on the surface, how to put it on a 3 grid? ________________________________ 发件人: Christophe Geuzaine <[email protected]> 发送时间: 2017年6月7日 7:42 收件人: Jin Yao 抄送: [email protected] 主题: Re: [Gmsh] apply background mesh to non-planar surface > On 4 Jun 2017, at 20:06, Jin Yao <[email protected]> wrote: > > Hi experts, > > Is it feasible to generate background mesh to non-planar surface, such as the > surface of a sphere? > > For planar surface, it is easy to generate a background mesh, which consists > of scalar triangles.
