Hi everyone,

I'd like to create a rigid beam/link between to H Beam in workbench.

 So I created 3 lines in SpaceClaim :

Hi,nnDid you make the additional line a line body? You can use comand object to change the element type in Workbench.nnRegards,nAshish Khemkan

Hi Akheamka,nnThanks for your answer. I'm very new to Ansys I'm not sure what you mean. All my lines are created in SpaceClaim (lines supposed to be rigid beam too). Then I choose sections for each line (I choose none for my rigid beams). And when I save my geometry and go to Model in mechanical prepost, only the lines with sections stay. My lines which I want to assign beam184 dissapear, I suppose it's because they have no section assign ?.i've tried to assign a random section to the lines supposed to be rigid beams and when I swap to mechanical prepost they stay and I can add some APDL command for thoses lines :et,matid,184nkeyopt,matid,1,1nkeyopt,matid,2,1nnMaybe I can assign them random section in spaceclaim and then in mechanical prepost when I add BEAM184 to those element I can cancel the section ?.I hope it's clear and not to fuzzy.nnThanks again for your time !

I suggest you insert a Fixed Joint, and set the Behavior to Rigid. Joints are found under the Connection folder in Mechanical.nThe Mobile side of the Joint will be one vertex, the Reference side of the joint will be the other vertex.n

Hi,nnThanks for the answer it's perfect Just one thing, will I be able to extract the efforts passing trought this joints between my two beams for my load case ?.Thanks again !n

Yes, under the Solution branch, insert a Probe, Joint and you can request the Reaction Forces and Moments going through the Joint Coordinate System.nIf you pick both vertices then create the joint, the Joint Coordinate System will be created halfway between the two vertices. You can then edit the Mobile and Reference scoping to put one vertex in each one since one of them will initially have two vertices.nThe origin of the Joint Coordinate System can be edited, but the method I described above finds the midpoint automatically.n
