Too much time for my simulation

Alaa Habrah
Hello everyone,

I am trying to solve an RC frame with infill steel late. when I solve the frame without the steel plate, I had no issue, but with the steel plate on, initially, the job run good untill it reached time of 3.3 where it started to have increments in the order of 10-6. now it is more than three days and the file size already passed 32 GB with the time still at 3.7. Please check my input file and tell me if there is a way to reduce the time of the simulation.

Change Viscosity parameter from smaller to larger for CDP.

Re: Too much time for my simulation

Jordy Sosa
I cant see your file because it is not attached , but I think the problem
has to do with material constitutive model, specially CDP, or maybe with
interaction between materials or at support.
