Hey Coros: That's like I did it in the evening. But I was forced to leave the room and therefore could not give my actual status. That far it also works, problem: The expansion is 0 for 0 Kelvin, but not for my reference Temperatur (given in Material constants). Normally the movement of the...

So my problem is: how can I include in the same simulation from my heat transfer the expansion?

ok, but if I have already heat-transfer steps, I cannot build up any static step...?

by the way: I use a heat-transfer step.

Hello! I have following problem: I simulated the temp. behavior of a satellite (time dependent). Now I want to visualize also the expansion/deformation due to temp-differences. Therefore I defined for my material also expansion coefficient. But I do not succeed in showing any...

nobody has got any idea? Also tips where to find further information would be very helpful. Thanks a lot

oh, the caption has a spelling mistake

Hello, since I am able to implement cavity radiation I have some questions concerning the physical model used by Abaqus to solve cavities: In the Therory manual I read that Abaqus only uses one Factor (Epsilon for emissivity) to simulate the material behavior. You can make it time dependent...

ok, thanks for your help. I solved the cavity problem, it was a version of Abaqus problem. In 6.8 you can use CAE to include cavity radiation. Thanks a lot!

Hey! We have some problems on our Abaqus Version and have to use 6.8 (we'll install tomorrow). I am a little bit afraid of not finding the interaction. Has anybody a little example file, where he Used AbaqusCAE to define a cavity definition. Just for me to look, if it is included in Abaqus 6.8...

Thanks a lot for your first steps. I just realized that at our institut there is 6.5 Version installed. Since which version exists this possibility under Interactions? thanks again christian

Hello Abaqus users, I have to do some "first principal" radiation Simulations with Abaqus on a satellite. I already included radiation from space to the space-craft and radiation to the ambient. What is more important is thermal radiation inside the space-craft. My first try would be to do it...
