Hello George, I have the same issue. I would like to fold and inflate a long 20 mm diameter tube, 3.5 meter long, made of airtight nylon. Due to lack of information, manuals and tutorials, I'm really upset and do not know how to make it. What have to be done first and what is next... Is there anywhere a full step-by-step tutorial, how to create and simulate an average airbag (incl. properties, material, cards assignment etc.)? What shall be done first: meshing, folding with Airbag folder, unfolded model, etc.? As I understood, there are different methods of simulation of the inflatable structures. Which one do I need? How to make an gas inlet hole and flow direction? What do you mean with "simulation method". Is it "Folding pre-simulation with Radioss"? Is there a manual how to perform it? Is there anywhere a tutorial, how "Example 4 Airbag" was made? Such questions I'm getting very often, due to lack of information. I have seen a lot of tutorials in Altair help, different presentations, but they are all imperfect, only providing basic information, without describing the process. I really have no imagination what I have to begin with. There are lot of separately described steps no correlating each with other in independent tutorials, but nowhere stays the full sequence of creating and simulation of an airbag Could you please suggest me a full manual (video, PDF, lecture) on how to create and simulate an airbag from scratch? Or maybe write an step-by-step list, what i need to do? I will really appreciate it! Thank you in advance!
Hello, I wanted to know how Radioss calculates at every time step the volume of a monitored volume, i did not find the answer in the theory manual. I'm using four monitored volumes type COMMU1, comunicated by dummy surfaces, but the geometriy is a little bit complex and during the simulation, the common surfaces are sometimes outside the monitored volumes as you can see in the image, the green surface on the top. How this impact What would be the difference between using multiple monitored volumes COMMU1 and only one monitored volume type AIRBAG? Thank you
