about fiber section

[mojtaba_khodayari]

hi,
i use fiber section in my work, changing the number of fiber in cocncrete patch affected the pushover analysis, when i use a mesh with 2 cm my analysis done but when i change it to 3 cm , my result faild.
i want to know is there any suggestion about number of dividing patch of concrete in buildrcsection.
with best wishes

you might want to research the topic.
yes, the finer the mesh, the better the results.
if you have a large model, you have to balance that with the computational expense.
