Ways to optimize my model

[DoraFitch]

Hello STKO Team, I'm modeling a four-span masonry arch bridge in 3D, consisting of three layers and materials. My analysis includes gravitational analysis for self-weight and applying an edge force on one arch. However, the self-weight analysis is quite time-consuming. Is this normal, or are there ways to optimize my model for faster analysis? Appreciate any tips you might have.

Hi, You can provide more details to help your out. Does it have solid elements?
Generally, the first stage gravity analysis should not take much time, however it depends on the number of elements in your model and analysis settings.
