  1. Hi, Thank you for your replies. Interesting Nguyen, I have never seen this kind of method. Actually I am using 2D shell elements- linear static analysis, how appropriate is this method? How does it affect the results? Probably it is advisable to do this outside your critical area? Actually I have been told that "TIED INTERFACE" is the feature I am looking for. Does anyone know, it this method possible in HyperMesh- RADIOSS Bulk Data Format?
  2. Hi all, I would like to make fine mesh in the critical area of the model and coarse mesh in general areas. I have seen one model how this was done using method I would like to get to know- see the attached figure. It seems that on the shared edge 2 surfaces are connected but with each second node unconnected. Does anyone know how to do this? It is important that 2 surfaces remains connected. I have read about mesh transition techniques in Hyperworks Student Guide but it does not say anything about this method. Thanks.
