Hi, I am pretty new to gmsh, trying to learn now to use sizing field. I created a poisson solution with getDP on a coarse mesh which I'd like to use as a starting point for a sizing function through mathematical manipulations.
I encountered the following problem: 1. I can load the pos file and modify the view via Plugin(ModifyComponents).Expression0 = "v0+1"; for example, but I could not find a way how to obtain Max/Min of the pos-field to normalize the sizing field range to say [1 2]. Also I could not find a complete list of which mathematical functions gmsh actually supports. 2. How can I convert a view to a field, which then can be used to create background fields as described in example t10.geo. I tried Field[0] = PostView; which gives me a segmentation fault when applying "mesh2d". Finally when applying the Lloyd smoother in the geo file the Recombine command seems to be ignored. Doing so in the graphical interface however seems to work. Thanks a lot, hj
