Layered Mesh

Hello everybody,

 

I have to mesh a sheet structure with Hypermesh. I know with Simlab it's relatively simple to create a layered mesh for thin walled structures that are meshed with 3D-Solid elements (See pink mesh screenshot). It's even possible to define the number of layers. Could please someone tell me if it's also possible to create a layered mesh in Hypermesh?

I tried to create a 2D mesh with 3 layers on sheet side faces. When creating the 3D-Mesh from 2D Hypermesh still creates large elements resulting in a single layer inside of the sheet structure (See green mesh screenshot). I tried it with different settings of 3D -->tetramesh --> 'Tetra mesh' but also 'Volume tetra' where I defined a element size that I thought should do the job but it didn't. Hope anybody knows what to do.

Is the only way to create a midsurface and divide the structure or are the better/faster ways?

 

Thank you.

    If you are using HyperMesh 2019 or 2019.1.1 latest release, then you could find option to define no of layer under tetramesh parameter and accomplish final terahedral mesh with tetramesh(first subpanel).This should generate layered element on thin region.
