Hello All, I have to do a transient analysis of thin composite film. Following are the requirements: 1. Time t=0 to t=0.01, Initial condition of Temperature=300 K. 2. Time t=0.01 to t=0.05, Temperature=505 K. 3. Run the analysis from t=0.05 until a stable solution is obtained. I tried...

Hello, In DM, how can I create two separate bodies which are connected to each other? Apprently, ANSYS would merge them as one body by default. I've checked the manual and put one of them into frozen body, they did separate as two. However, I can't transfer the model to Mechanical, I...

Hello, I have a quick question. I created some models on Ansys Workbench 13, but when I tried to open them in Ansys Workbench 12.1, I couldn't. It said that I cannot open a file created in a newer version! Is there a way to save it in a different format in Ansys 13 , so it'd work in Ansys...

Hello, I am used to use Ansys classic in my work. I just started to learn Ansys Workbench. I am modeling a copper jacketed lead bullet. I modeled the copper case the internal lead part. Now I have two solids. Is there a way to mate them, and use them as one assembly, of solids? Thanks

I am new to Ansys and I wish to model 3 very thin layers of different materials bonded to each other. Can someone please reply back. Thank you

Hello all! I'm modeling with ANSYS 12 (workbench) an assembly made up by components which are initially in "gap" condition, going in contact after deformation due to the applied pressure load. I tried in a "static structural" analysis by settings the manual contact regions type "frictionless"...

Hello all, I use ANSYS at work quite a bit and I know others in the forum propably do also. I mainly model thermal, stress, and combined thermal-stress interactions on all sorts of geometries. I have noticed a lot of the questions asked in here on ANSYS are very simplistic and probably deal...

Hi, what sort of elements would you use on a tensioned cable, pinned at either end, that is to have a uniform load across it ? a single link8/10 element can't work because you can't put a UDL on it, only 2 nodes...Mulitple link elements won't work because there is no stiffness at each node...
