I am trying to run a material non-linear analysis on my sample, but I keep getting *** ERROR # 4966 *** Minimum time increment reached, analysis aborted.
Hello! For context, I am making a simulation of a 3-D tensile sample. The sample is compromised of a PETG base with carbon fiber filaments implemented inside the base. I am trying to run a material non-linear analysis and I keep recieving *** ERROR # 4966 *** Minimum time increment reached, analysis aborted.
I have an idea that it might have to do with the auto contact setting I implemented or how the sets I created for the pulling load and boundary condition were made but I could be wrong. Please let me know if I need to clarify any information.
Attached is my hm file.

Hi
I did add a RBE2 to the left side holding the specimen and then added a rbe3 for loading on the right side!
Updated the BC and force set to just include 1 single node each
Model runs fine now.

Hi
regarding the loads, is supposed to have FORCES on all nodes in you force set?
A good start would be to apply displacement control on the "right side" instead of forces.
Regarding time step min you can control this with the nladapt card
$HMNAME LOADSTEPINPUT 3"nladapt"
NLADAPT 3DTMAX 0.1DTMIN 0.0001
Kind regards

/johanHello!
Thank you so much! I'm very new to Hyperworks so I am trying my best to learn as much as I can. The reason why I wanted to make a set is because it was my understanding that doing so for a force for example would mean that the end would have a uniform pulling load. But it turns out I had a multiple amount of loads.
I've never had to use the rigid body command but looking into it, it just seems like a better way to run the simulation. I should have looked into this before.
Again, thank you for your help!
