Quasistatic Simualtions

[jiangr100]

Hello, I've seen in this page here https://polyfem.github.io/json_defaults_and_spec/ that quasistatic simulation is a possible feature, but i get "warning: Inconsistent specifications: /time/quasistatic is neither an optional or a mandatory field." when adding it to my json file. Is there any way to run quasistatic simulation in PolyFEM or this is not supported? thank you!

Can you post the JSON file you are using? Are you doing something like

"time": {
"dt": 0.01,
"tend": 1,
"quasistatic": true
}

I believe you might need the dt and tend parameters explicitly to tell it what the quasi-static steps should be. Otherwise if you want a one-step static simulation then you can achieve this by omitting the time field completely.

sorry for the late reply, yes I've done exactly that and it showed me the error message. And I do need multiple steps of quasi-static simulations. Did you successfully reproduce the problem?
