Hello, I am using gmsh for modelling 2D components and I am trying to find out how I can set a thickness to the plate/shell elements. First I was thinking about assigning regions of different thicknesses to different physical groups but by this approach I can specify only a constant value which is not what I need.
According to this conversation from the mailing list it should be possible. > > Hi Mathieu, > Have a look at the Gmsh Tutorial 7: > http://geuz.org/gmsh/doc/texinfo/gmsh.html#t7_002egeo > HTH > Ruth > Dr. Ir.

In my opionion this examples controls the size of the elements by using a *.pos file and not controlling the thickness. So my question is how I can assign a thickness for example to a rectangle area as a linear function from 1 to 10 in x-direction and constant in y-direction? Best regards Julian
