    Parts going through eachother when load is applied

    It's also giving me an over constraint check, all the interactions I have I personally think are important to establish boundaries and contact so parts don't run into eachother. Do you mind looking at it and seeing what interactions are redundant? I've attached the file...

    Parts going through eachother when load is applied

    I tried using the refinement rules to make the necessary parts more refined than others. I'm getting a "displacement increment for contact is too big" error and I have been getting it for a while. What can I do to fix this?

    Parts going through eachother when load is applied

    I tried fixing this issue but the problem is still arising that the part isn't acknowledging the neighboring part and is just moving right through it. General contact was also tried previously but wasn't successful because even though there was a load applied (a significant one too so no risk of...

    Parts going through eachother when load is applied

    What about contact between two non rigid bodies

    Parts going through eachother when load is applied

    I tried using a displacement on the top of the part I want loaded but that is doing the same thing as if I applied the body load. When creating the mesh originally we created a tet mesh for all of our individual parts. What do you suggest we do to make sure our master-slave assignment is done...

    Parts going through eachother when load is applied

    I've attached pictures of the progression of what is happening to help describe what I mean. https://files.engineering.com/getfile.aspx?folder=f02366ee-a05e-4f3e-b4d0-5afc80ecadbf&file=Abaqus_Files.zip

    Parts going through eachother when load is applied

    Hello, I'm having an issue where I'm applying a body load on one part and expecting it to compress the part it is touching but instead of compressing the nearby part it is simply going through it without applying any stress on the touching part. Right now, I have surface to surface contact...

    Too many attempts made for this increment

    We tried displacement load under boundary conditions instead of the concentrated force under loads. With this we got the error "THE ANALYSIS HAS BEEN TERMINATED DUE TO PREVIOUS ERRORS. ALL OUTPUT REQUESTS HAVE BEEN WRITTEN FOR THE LAST CONVERGED INCREMENT" Is there a way to find out what the...

    What do you mean by make use of symmetry. Also fyi if it makes a difference our part files originated from solidworks not abaqus I know sometimes that limits changes to the assembly you can make.

    Too many attempts made for this increment

    We just made all the rigid bodies fixed with exception of the rigid that experiences the load which we made fixed in all directions except for the y direction. Because of this should we no longer have a risk of RBM? We also got the file to run with everything defined in this file EXCEPT the...

    Too many attempts made for this increment

    Where is the option to run this model/how do you. Also what kind of boundary conditions or contact should we apply to our two non-rigid parts? I've attached an updated file with the additional fixed rigid body. The third rigid body with the load applied should compress the two non rigid...

    Too many attempts made for this increment

    I changed the encastre BC to the reference point but it still gave the too many attempts error. Automatic stabilization I believe was already on in the step settings. We did consider the displacement option under loads however this option in our case isn't ideal since the criteria given to us...

    Too many attempts made for this increment

    Okay, now we're back to the too many attempts made even with your initial comments added in.

    Too many attempts made for this increment

    Here's what we have so far with the added suggestions you made. Still getting the license error and are pretty sure that the only thing user defined we could potentially have is with our materials we added. Could you take a look? Thanks so much for your...

    Too many attempts made for this increment

    We did that previously, we used a penalty global property with friction factor .577. Is that fine or do you think that's where our error is?

    Too many attempts made for this increment

    What kind of load should we use in order to apply to a reference point? We've tried concentrated force. How do we avoid calling for subroutines if we just want to use a general contact condition?

    Too many attempts made for this increment

    After adding a general contact and running a job it gives the error, "The user parameter is not available for the current license type". Is there a way to go about this error? I also added the load to a reference point on the ourside of the surface I initially wanted to the same job but I'm...

    Too many attempts made for this increment

    Thanks for the response! How do we apply the boundary condition to a reference point if we want the force applied to the entire surface? What would be a good contact definition?

    Too many attempts made for this increment

    Hello! Trying to model compression tube fittings but keep coming across the error of "too many attempts made for this increment" Our load is a uniform load applied to the surface as pictured in the attached file at about 4600 lbs. We've already looked at comments to try to fix this by changing...
