Have a look at size "Fields" (e.g. tutorial/t10.geo). > -- > Best wishes! > > Sincerely yours, > Liu Xiaoyu > > <problem1.geo><problem2.geo>_______________________________________________ > gmsh mailing list > [email protected] > http://www.geuz.org/mailman/listinfo/gmsh -- Prof. Christophe Geuzaine University of Liege, Electrical Engineering and Computer Science http://www.montefiore.ulg.ac.be/~geuzaine _______________________________________________ gmsh mailing list [email protected] http://www.geuz.org/mailman/listinfo/gmsh
