I got the solver to converge with the surface consisting of nodes and the yellow reference node in the middle.
Would you suggest using the distributing coupling element with 1D -> RBE3 method instead, and if so - why?
Or are both methods for tracking and obtaining the centroid...
I thank you, dear Sir.
With regard to the coupling method - I'd guess that when I use shells, that structural is the way to go, as the shells I use have rotational D.O.F's.
With regard to the two coupling methods (structural and continuum) - it seems that continuum is default. I use shells and...
Hi again FEA way. I am using the Abaqus solver, so everything should be the same. HyperMesh is just an excellent tool for pre-processing and mesh-control. I am using the Abaqus user-profile so it should be the same in the input file.
The inp file:
I just created a node in the middle - it's...
Ok, I can't seem to get Abaqus to even solve this.
What I have done is:
With the following card:
I have tried both with and without the coupling and weighted option enabled.
I am using HyperWorks - do you have any suggestions?
mgriebel - thank you. I am not familiar with Nastran, but I will look into the manual and read about the RBE3 element. As I wrote in my second post I was actually looking into the coupling of kinematic and distributing, but I understood it solely as imposing kinematic constraints and...
Hi mgriebel - is this possible? I think I want the reversed result - instead of imposing a load/moment/displacement I want to register the displacement of a reference node.
Hi again and thanks for listening. I am currently looking into coupling kinematic/distributing. But I guess I have to use a script somehow as both of you have suggested. Maybe if I get time I'll try and compare the coord results to the results gained using the soft spring.
The component I am...
Hi all, I am currently looking into the matter of applying some loads to a large structure consisting of many components.
To make it all simpler I have added a picture to resemble my problem.
I'd like to somehow track the displacement of the pipe center as shown:
It'd be awesome, if I...
Hi FEA way, thanks for your reply. I have tried out the matter, that you have described and it seems to be running - but not converging as it is down in incredibly small time steps/increments.
Hi everyone.
What I am trying to achieve is pre-tension of some supportive tubes. The reason is that the tubes support a pipe, which is experiencing thermal expansion. To level out the displacement due to heat-transfer, then the tubes are moved a given displacement as a pre-tension.
In first...
