Re: [Gmsh] Boolean Fragments. Créate 3d mesh from surfaces. Surface Loop creates aditional surfaces

Perfect. The problem was related with the previous builds.Now is totally solved. Thank you very much for your time. Best Regards Jacob Enviado desde Correo para Windows 10 De: Christophe Geuzaine Enviado: miércoles, 7

Re: [Gmsh] Missing surfaces in mesh when using Boolean operators

Hi Isabela, You may use BooleanFragments instead of BooleanDifference. That seems to work: Try the following at the end of your file: /* voxcyl() = BooleanDifference{Volume{v};}{Volume{union19()}; Delete;}; //Physical Volume(0) = {voxcyl()}; */ // --- Definition of Final Volume

[Gmsh] Non constant element sizes on a BSpline

Hello dear Gmsh users, I would like to mesh a BSpline using non constant element sizes. Here is a MWE: Point(1) = {0 , 0 , 0, 0.2}; Point(2) = {-0.1, 0.5, 0, 0.2}; Point(3) = {-0.1, 0.8, 0, 0.1}; Point(4) = {0 , 1 , 0, 0.1}; Point(5) = {1 , 1 , 0, 0.2}; Point(6) = {1 , 0 , 0, 0.2};

Re: [Gmsh] Boolean Fragments. Créate 3d mesh from surfaces. Surface Loop creates aditional surfaces

Is thiis would be related to the normals of the surfaces?. I noticed that the normals is oriented outward. So i tried to invert the normals but i cannt find a way to do this. I attach a figure below. Best Regards Jacob[cid:image002.png@01D39FEA.A3D5FC70] Enviado desde
