Hii,

I am trying to model RC Concrete columns with different materials. I used MW model to define UHPC, ECC, and Normal concrete with exponential softening. For mild steel, I used the reinforcement option with the bi-linear model. The boundary conditions are well defined. Anyway, the model has problem with converging from the beginning with indicating that material solution has failed for some elements at a very small displacement. Can anyone please help me with this issue?

That is my email in case: husam.farghal1@gmail.com

Hi,

Please see if the answer on your earlier thread helps: Reinforced Concrete (ansys.com)

Hi,

Thank you for your response. I watched this video many times and I do not think it can be help for my case. I am using exponential MW and he used linear trend. Sorry, I was not able to see your response before.

I still was not able to fix the issue. Can anyone help me through this matter?

I already learned abaqus and I will run the analysis in there. I do not want my work on Ansys to be a waste of time and I need help because I am out of any option. I want to validate my result using both software.
