RE: ansys workbench help urgent

I looked your model. I could not understand your question. could you show the position that you want to fix it in a picture.   

RE: ansys workbench help urgent

Create the area that you want to fix it as a separate area (you have to divide your area).

RE: ansys workbench help urgent

Hi, you can fix a face (it is not possible to fix just a part of face). The face that you have is in 360 degree; therefore you have to divide this face to have a separate part with 120 degree.    

RE: ansys workbench help urgent

kkk it means in proe i have to change the face and how can i apply bolt pretension

RE: ansys workbench help urgent

yes, you have to do that in proe or in Ansys  design modeler. If you search "bolt pretension"in workbench help, you will find an example about that.
 
 

RE: ansys workbench help urgent

actually you can do that 120 degrees thing in ansys. At desing modeler you need to skecth your area for 120 degrees after that extrude it, at "operation" tab choose "imprint", and you now seperated your face. you can apply now fixed support to area of 120 degrees.  

RE: ansys workbench help urgent

You know if there are no side forces why not do symmetry? That takes care of a lot of the problem unless you are looking at buckling.
