I have modeled a bottle with varying thickness along the length. I have considered the shell elements and the thickness is given in the input file that is different thickness at different nodes , actually it is an output of another software. What I have to do is increase the wall thickness and check the performance. I have copied all the nodes and corresponding thickness values in excel and increased the thickness values by 0.3 mm and copied it again in the input file with node numbers and increased thickness values the model was working fine and I got the results as expected. But, I did the same thing increasing the thickness by 0.1 mm and another by reducing 0.5 mm now the model itself is not openening leave alone the thicknesses It is a wiered problem I am facing. what might be the reason? It should atleast open the model I suppose because I am just changing the thickness values more over it worked well with increase in 0.3 mm.
Please help me regarding this.
Thanks in advance
