There are a few things to put into your study to make it, foremost, stable but not overly restrained. Over-restrained setups impact the validity of your results and under-restrained setups may not solve at all.
In your setup you would want to start by creating the fixture that represent actual objects in your analysis. The first fixtures you would make would be "Use Reference Geometry" (SOLIDWORKS Help - Simulation: Using a Reference Axis) fixtures using the sketch elements for your top cables as reference geometry. In this way you are retraining just the movement axially along the top cables.
The next real object you wish to represent is your load as it will provide additional stability to the setup. You would use a "Remote Load/Mass (rigid Connection)" (SOLIDWORKS Help - Simulation: Remote Load (Rigid Connection)) on the 4 holes to apply the 15000 lb downward force. The use of the "Rigid Connection" is so that the two beam members are rigidly connected to each other to keep them from collapsing together. The load itself becomes a sort of "virtual" beam member between the two.
These definitions do not provide the setup with full stability though. One rigid body translation remains unrestrained. To fix this a split line curve would be applied along the symmetry plane of the beam members to create an edge along the plane of symmetry. This edge would then have its own fixture applied to keep the movement normal to the symmetry plane restrained. This fixture's real life analog is whatever you do to keep the load from swinging on the cables.
With that all in place. You should get some results to look at.
Attached is an example of the setup that made these results.
Dear Ryan Dark
Thank you very much for answering my question and helping me with this problem I am very appreciated for your support
I did create fixture for bottom and on top as you instructed to keep the angle from moving but I don't know the ring move out
I did make contact set and it gives me warning
I made 2 studies one I fixed the bottom and pull and other I fixed the ring and pulled from bottom
could you kindly one more time look at my assembly and tell me what am I doing wrong
again thank you very much for helping us

Looking at your setup, the fixtures and load seem to be fine. Whether you place the load pulling up from the top or down from the bottom should not make much difference. Your own study seems to go a step further adding bolted connections and the lifting lugs which will give a better representation of the real life scenario than directly applied fixtures and loads.
Hi Dear Ryan
Can you tell me GoEngineer offer Simulation training class on-site or online
and which one you recommend I am located in Toronto Canada and I don't mind traveling to your city
to learn Simulation software
It was my lucky day that you helped me with this problem I keep watching the youtube video from GoEngineer and it is amazing
I'm glad that post helped. Our offices are in the western and southern USA mainly in California and Texas. Our full training schedule for all offices can be found here (GoEngineer SOLIDWORKS/Simulation Training Calendar). We are adding online training classes but I am unsure if any are scheduled for Simulation so I will check and get back to you on that.
EDIT: Our full online training course list can be found here (GoEngineer - GoLive Online SOLIDWORKS Training). There are a couple courses offered (SOLIDWORKS Simulation and SOLIDWORK Simulation Pro) and scheduled course dates are in March and June.
