Soft body simulations
Soft body simulations
(OP)
Dear co-pro!
I need some help simulating a air ballon that is filling with air. Is this possible in I-deas?
Does I-deas have soft body simulation capabilities?
Anyone with experience in this area please leave an input.
Thanks!
Cheers

RE: Soft body simulations
Although I have not much experience with such an analysis, I think that I-DEAS is not capable of it. I assume that you want to simulate how the empty balloon is filled with gas and subsequently gets larger until it is completely filled. I see the following obstacles for I-DEAS:
1. You'll probably have to consider special material laws for the balloon skin, they're probably not available in I-DEAS
2. I-DEAS cannot cover large displacements which occur during the inflation of the balloon
3. Depending on what you want to analyse, you'll have to perform a CFD study in order to determine the velocity/pressure field of the gas filling. In the worst, You end up with a coupled flow+structural analysis (gas + ballon skin)
However, you could use I-DEAS as preprocessor, i.e. generate geometry, mesh the whole thing, apply boundary conditions and export the FE-model to your chosen analysis tool. If you're concerned with 1. and 2., one of the "big players" in FE analysis (ANSYS, NASTRAN, ABAQUS) should do.

RE: Soft body simulations
Thats what i though!
Is there any CAD software that allow soft body simulation and also being user friendly. It is not as much of a FEA as it is suposed to be an animation with real and natural forces and patameters.
I mean, here we are in a world full of soft bodies and we only are able to work with a fraction of those that are so called solids..!!!! I think thats strange. Engineerign science, with all its complexity is looking pretty primitive considering the previously mentioned things.
Thinks about it...:)
Cheers you all
