Hi Stéphane,
Is it possible to use two overlapping meshes and to project information from one mesh to the other one ? Since this question is unclear, here is an example: 1) Suppose I have two meshes: - a first one covering a certain volume, - a second identical to the first but with an extension so that it covers a bigger volume. In the common region, element, nodes positions and numbering are identical. 2) I would like to solve a physical problem on the first mesh and use the results as data for the second physical problem (solved on the second mesh). I think it would involve somesthing like this : mesh M1 = read(gmsh,"small mesh.msh"); mesh M2 = read(gmsh,"large mesh.msh"); // Initial values femfunction t1(M1)=0; femfunction t2(M2)=0; //.. solve a first problem on M1 to get t1 //then t2=t1; //Projection of t1 on t2 on the common part //.. solve a second problem using t2 as property One of the problem, I think is to define the value on the non-common region (a constant value would be OK). Is it possible with ff3d? Thanks, Dominique. Créez votre adresse électronique [EMAIL PROTECTED] 1 Go d'espace de stockage, anti-spam et anti-virus intégrés.
