Is Static Analysis applicable to Functional Molded Part?

Hi Everyone,

I have a Funtional Moled Part and have tried to apply static analysis on it, but the part has only one big surface available for the restrains and the loads definition, making the analysis unapplicable.

I tried to deform the surface to meshes and do analysis again, but it failed. Can somebody give me a hand?

I noticed that in the sample01.CATAnalysis the part is Part Designed.

Thanks,

If I understand you correctly you can't apply boundary conditions because when you try to add loads, or restraints or .... the whole surface\volume gets pick.
Or am I totally of?
Try splitting the surface into areas where you want to apply your BCs. When you do the Split, select the Datum icon first so that split surfaces created will be isolated. Use the option Keep both sides. Then Join the surfaces together. This will give you the same volume you started with but now you can select the areas that were split to apply your BCs to.
This is similar to the method of splitting and sewing a surface onto a part body.
 
You shouldn't need to select the Datum icon first. If you leave your split associated to the original surface and the split curves, you can easily modify them if you find that you need to change something.
 
I tried that but once in the GPS workbench CATIA sees the split surfaces as individual surfaces (not joined). In the first example I tried I took a rectangular surface and split a circle in the center (without using the Datum icon). When meshing I had to mesh each surface individually. Next I restrained two edges and applied a load to the circular surface created in the previous step. When I ran the analysis it failed because the circular surface was not restrained.
So in my second example I used the Datum icon when splitting then joined the two surfaces. When meshing all I had to do was mesh the joined surface. I applied my BCs the same way and the analysis ran.
 
Thanks Everyone For Your Replies.
