Error in plotting the mesh file generated from gmsh

Hello,

I have created an airfoil geometry in SolidWorks and meshed it in gmsh. When I tried to plot in FreeFEM++4.12 version (Later i will solve for 3D elasticity problem), it is showing Error. Code is written below:

load “msh3”

string meshFileName = “snlwindpact_testn.mesh”;
mesh3 Mesh = readmesh3(meshFileName);
plot(Mesh, wait=1);

Output log file is below:

read mesh ok 0Mesh3, num Tetra:= 0, num Vertice:= 9047 num boundary Triangles:=
18096
– Mesh3 : snlwindpact_testn.mesh, space dimension 3, num Tetrahedron elts 0,
num Vertice 9047 num Bordary elts 18096
ERROR!!! The old SURFACE mesh3 is obsolete, please use meshS type

According to your output there are zero tetrahedra in your mesh. That’s probably not what you intended, right? Check your mesh generation.

Thank you henkel. I will recreate the mesh.
